Location: San Francisco, CA | New York City, NY | Seattle, WA About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the role Claude Science is an AI workbench that gives researchers a single environment for work that today spans dozens of disconnected tools — literature, specialized databases, scientific computing, analysis, and publication-ready outputs. Claude Science already renders protein structures, genome tracks, and chemical structures natively, and coordinates multi-agent workflows with built-in review for citation and calculation errors — and we're just getting started. Much of this is being built 0→1 right now, in a category no one has defined yet. We're growing the Claude Science product team. As a Product Manager on Claude Science, you will own a major area of the roadmap end to end — think expanding into new scientific fields, landing new model capabilities with researchers, or making the workbench ready for enterprise R&D teams — and help shape the overall product direction alongside the rest of the team. You'll spend real time with researchers in academic labs, biotech and pharma R&D, and research institutes to understand how science actually gets done — from hypothesis to analysis to publication and beyond— and turn what you learn into shipped product. You'll partner directly with our research teams to make the models better at science, help decide which fields and workflows we go after next, and shape what it takes for Claude Science to be trusted in enterprise and regulated research environments. We're looking for experienced product managers and founders with technical depth: people who can learn the unique needs of a structural biologist or a computational chemist, get in the weeds of model transcripts and evals, and still zoom out to help define a product category. We're open to deeply technical product experts who are excited to support scientific discovery; expertise in a scientific field is not required, but the ability to ramp in a new domain quickly is paramount.You thrive in ambiguity, uncover non-obvious use cases for nascent capabilities, and bring those insights back to research. Our north star is for Claude Science to accelerate scientific progress — across biology, chemistry, physics, and beyond — from early discovery through real-world application, by an order of magnitude. Key responsibilities Own vision, strategy, roadmap, and execution for a major area of Claude Science, and contribute to overall product direction in a category that is still being defined Spend meaningful time with working scientists — in interviews, working sessions, and key customer conversations — and synthesize what you learn into clear priorities, requirements, and success metrics Partner with research to make Claude better at science: define target behaviors, build and shape evals grounded in real scientific workflows, surface failure modes from real usage, and feed them back into model development Drive model and feature launches in your area end to end: define readiness criteria, coordinate across research, engineering, design, and go-to-market, run early access programs, and make sure launches land well with researchers Identify which scientific domains, data sources, tools, and integrations Claude Science should support next, and build the case with evidence from users, usage data, and the broader landscape Prototype ideas yourself with Claude to validate them before committing engineering time Work with safeguards, policy, security, and go-to-market partners so that powerful scientific capabilities reach trusted researchers responsibly, including in enterprise and regulated research settings Drive enterprise readiness  — security and compliance reviews, admin and deployment controls, and the procurement realities of pharma and biotech — so large organizations can adopt it with confidence Prioritize ruthlessly across a broad surface — scientific domains, customer segments, and competing workflows — and make clear calls on what our products serve deeply first, holding the line on MVP versus ideal state Define how success is measured for AI research and development products — adoption and retention among working scientists and operators, time-to-result on real analyses, trust in outputs — and use those measures to steer planning Maintain an objective, current view of the AI-for-science ecosystem — models, tools, benchmarks, and competitors — and of where Claude Science stands within it Minimum qualifications You might be a good fit if you: Have product management experience shipping technical products in close partnership with engineering and design, or equivalent experience driving product direction as a founder, engineer, or scientist Have a deeply technical background — enough to reason with domain experts about their workflows and to diagnose where and why a model is falling short on a scientific task Have a strong grasp of AI and LLM concepts, use AI tools daily, and are comfortable going deep on model behavior, prompting, and evaluation methodology Are data-driven: you ground prioritization in usage data, eval results, and evidence from users rather than intuition alone Have strong user empathy and can synthesize vague or contradictory feedback from expert users into actionable priorities Navigate and execute amid ambiguity as a first-principles thinker, flexing across scientific domains based on the problem at hand and finding simple, easy-to-understand solutions Communicate clearly in writing and can align research, engineering, and go-to-market stakeholders through influence rather than authority Think carefully and creatively about the risks and benefits of putting frontier scientific capabilities into the world, beyond past checklists and playbooks Preferred qualifications 8+ years in product management or equivalent product leadership, including taking products from 0 to 1 and scaling them; founder experience is a plus An advanced degree or hands-on research experience in biology, chemistry, physics, materials science, or a related field — or experience building software for scientists (e.g., computational biology, cheminformatics, lab informatics, simulation, or scientific data platforms) Have personally built evals or benchmarks for model capabilities, ideally agentic or scientific ones Experience shipping products into life sciences, pharma, or other regulated research environments, including familiarity with their data governance and compliance expectations A track record of launching ambitious products that found distribution or commercial success Experience designing trusted-access or staged-rollout programs for sensitive capabilities A creative, hacker spirit and a love of solving hard puzzles The annual compensation range for this role is listed below. For sales roles, the range provided is the role’s On Target Earnings ("OTE") range, meaning that the range includes both the sales commissions/sales bonuses target and annual base salary for the role. Annual Salary: $305,000 — $385,000 USD Logistics Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience Minimum years of experience: Years of experience required will correlate with the internal job level requirements for the position Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices. Visa sponsorship: We do sponsor visas! However, we aren't able to successfully sponsor visas for every role and every candidate. But if we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this. For roles performing work in California: We will consider for employment all qualified applicants, including those with arrest or conviction records or criminal histories, in a manner consistent with the requirements of applicable state and local laws, including the San Francisco Fair Chance Ordinance, the City of Los Angeles’ Fair Chance Initiative for Hiring Ordinance, the Los Angeles County Fair Chance Ordinance for Employers, and the California Fair Chance Act. We encourage you to apply even if you do not believe you meet every single qualification. Not all strong candidates will meet every single qualification as listed.  Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you're interested in this work. We think AI systems like the ones we're building have enormous social and ethical implications. We think this makes representation even more important, and we strive to include a range of diverse perspectives on our team. Your safety matters to us. To protect yourself from potential scams, remember that Anthropic recruiters only contact you from @anthropic.com email addresses. In some cases, we may partner with vetted recruiting agencies who will identify themselves as working on behalf of Anthropic. Be cautious of emails from other domains. Legitimate Anthropic recruiters will never ask for money, fees, or banking information before your first day. If you're ever unsure about a communication, don't click any links—visit anthropic.com/careers directly for confirmed position openings. How we're different We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills. The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences. Come work with us! Anthropic is a public benefit corporation headquartered in San Francisco. We offer competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.

To find out more, visit our LinkedIn https://www.linkedin.com/company/halter-limited & Instagram https://www.instagram.com/lifeathalter/. ABOUT THE ROLE Halter's component suppliers are predominantly based across Asia. The components they produce have to be right before they ever reach our contract manufacturers. When something is wrong, we need someone on the ground who can get to the root cause fast, push through to a real fix, and prevent it from happening again. The Supplier Quality Principal is Halter's senior technical authority embedded in Asia. You'll lead highly technical supplier audits, own complex quality problem-solving at our suppliers, and work directly with both suppliers and Halter's design teams to ensure that what comes off a supplier's production line meets the standard we set. You'll operate with a high degree of autonomy, covering a portfolio of suppliers across the region and acting as the technical bridge between our Asia supply base and the Halter team in Auckland. This is not a compliance role. Ticking audit checkboxes and filing reports is not what this job is about. The best person for this role is someone who goes deep: who can walk a production line and immediately identify what's controlling quality and what isn't, who can sit with a supplier's engineers and work through a failure mode from first principles, and who knows the difference between a corrective action that actually solves a problem and one that just looks good on paper. You'll report to the Head of Supplier Quality and work closely with Halter's hardware design and operations teams. When there's a quality issue in Asia that needs solving, you're the person we call. You'll be measured on the technical quality of audits, the speed and effectiveness of issue resolution at suppliers, and your ability to build supplier capability over time. WHAT YOU'LL DO TECHNICAL SUPPLIER AUDITING - Lead technically rigorous audits of Halter's component suppliers across Asia, going well beyond system compliance to assess process control, measurement capability, and the reliability of how suppliers actually build and inspect parts. - Identify the real drivers of quality performance at a supplier, not just the documented procedures, and develop clear, prioritised findings that distinguish between critical risks and cosmetic gaps. - Conduct pre-qualification audits of new suppliers, assessing their technical capability and readiness to meet Halter's design and quality requirements before commitments are made. - Run periodic surveillance audits to verify that corrective actions have been implemented effectively and that quality performance is being sustained. - Develop and continuously improve Halter's audit methodology and supplier assessment criteria, ensuring audits capture what actually matters for component quality. TECHNICAL PROBLEM SOLVING - Own the resolution of complex quality issues at suppliers, using first-principles analysis to identify root cause and drive effective corrective actions rather than superficial fixes. - When a production failure or OQC rejection occurs, lead rapid on-site analysis with supplier engineers and Halter's design team to understand the failure mode, assess risk to in-flight inventory, and define the fastest path to resolution. - Work with suppliers to improve their process controls, measurement systems, and inspection methods so that quality issues are caught and corrected at source, not downstream. - Coach supplier engineering teams to develop their own capability for root cause analysis and corrective action, building their ability to self-solve rather than depend on Halter for every issue. - Escalate issues clearly and early when resolution is taking too long, a supplier is not engaging in good faith, or a quality risk to production is emerging. QUALITY ASSURANCE SPECIFICATIONS - Implement and maintain Halter's quality assurance specifications at suppliers, ensuring specifications are understood, accepted, and consistently applied across the production process. - Work with Halter's hardware design team and the Head of Supplier Quality to refine QA specifications where field experience, audit findings, or supplier feedback reveals gaps or ambiguity. - Ensure that when designs evolve, updated specifications are communicated to suppliers, implemented correctly, and re-validated before affected parts re-enter supply. - Challenge specifications that are unclear, unmeasurable, or misaligned with what suppliers can realistically control, bringing engineering and operations teams to a better standard. PART APPROVAL AND ONGOING COMPLIANCE - Support supplier-side part approval activities, ensuring new and revised components are formally validated against Halter's specifications before production release. - Maintain a clear picture of approval status and open quality issues across the suppliers in your portfolio, tracking corrective actions to closure and flagging risks to supply continuity. - Collaborate with the Head of Contract Manufacturing Quality when parts that pass supplier OQC fail IQC at our contract manufacturers, working to determine whether root cause sits with the supplier process, the OQC criteria, or the incoming inspection. SUPPLIER DEVELOPMENT - Build genuine working relationships with quality and engineering counterparts at key suppliers, creating the trust and technical credibility that allows hard conversations to happen fast. - Identify where suppliers have systemic capability gaps and develop structured improvement plans that address root cause, not symptoms. - Share Halter's standards, expectations, and technical knowledge with suppliers in a way that builds their capability over time rather than creating dependency.   WHAT YOU BRING - 15 or more years of experience in supplier quality or manufacturing quality for complex electromechanical hardware, with a proven track record of solving technically difficult quality problems at suppliers. - Deep manufacturing and process engineering knowledge. You understand how parts are made, what drives process variation, and how to identify whether a supplier's process is actually in control. - Exceptional audit capability. You conduct audits that go beneath the surface, uncover the real quality risks, and produce findings that drive meaningful improvement. - Strong first-principles thinking. When you see a quality failure, you work back to the actual root cause, not the nearest plausible explanation. - Experience with QA specification development and the ability to assess whether a specification is clear, measurable, and correctly implemented at a supplier. - High proficiency in both English and Mandarin (written, verbal, and reading). You can work directly with Chinese engineers and leadership without translation. - Comfortable operating autonomously across a portfolio of suppliers. You manage your own priorities, escalate the right things at the right time, and don't need close supervision to stay effective. - Firm, fair, and direct with suppliers. You hold a high standard, push back on inadequate corrective actions, and maintain a relationship that is professional and productive even when conversations are hard. - Willing to travel regularly across APAC. A significant portion of your time will be on-site at suppliers. - A Master's degree in Engineering or a related technical discipline is preferred.   JOIN OUR TEAM Halter is committed to promoting a diverse and inclusive workplace — a place where we can each be ourselves and do the best work of our lives. Research shows that while men apply to jobs when they meet an average of 60% of the requirements, women and under-represented groups of candidates tend to only apply when they meet every requirement.

Location: Remote-Friendly, United States About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the role Anthropic is building AI compute at a scale and pace that outruns what off-the-shelf data center equipment was designed for. Much of the power and cooling equipment behind our next campuses — battery energy storage systems (BESS), grid-forming and grid-following inverters, solid-state transformers (SST), E-STATCOM and other power-quality devices, medium-voltage switchgear, UPS, and liquid-cooling systems — is either new to the market, new to the supplier, or being built at a volume the supplier has never shipped before. The NPI Engineer owns the path from "the supplier has a design" to "the equipment is qualified, manufacturable at rate, and running reliably on site." You sit between our electrical and mechanical design teams, our supply chain and quality teams, and the supplier's engineering and factory organizations, and you make sure every new product or major variant clears the gates — EVT, DVT, PVT, FAT, SAT — before it is trusted with production load. This is a hands-on role: you will spend real time on supplier factory floors, in test labs, and at site commissioning. What you'll do Own the NPI program for each new power or cooling product (BESS, inverters, SST, E-STATCOM, MV switchgear, UPS, CDUs, chillers) from concept selection through ramp, including the gate schedule, exit criteria, and risk register. Drive early supplier design engagement: translate our site requirements (fault current, grid interconnection, harmonic and ride-through requirements, thermal envelopes, footprint, serviceability) into product requirements and specifications the supplier can build to, and negotiate trade-offs with their engineering teams. Lead DFM/DFT/DFx reviews with suppliers so designs are manufacturable at the rate we need, testable in the factory, and serviceable in the field. Plan and run prototype and pilot builds: define EVT/DVT/PVT scope and sample counts, witness builds, own test plans (type testing, HALT/HASS, thermal, EMC, protection coordination, functional and integration tests), and drive root cause and corrective action on every failure. Qualify the product for deployment: define and execute first-article inspection, factory acceptance testing (FAT), site acceptance testing (SAT), and integrated system testing with the rest of the electrical and cooling chain, and sign off on production readiness. Hand off to steady state: transfer qualified products, control plans, test procedures, and known-issue lists to the Manufacturing Quality and Supply Chain Delivery teams, and support them through the first production ramps. Build the reliability picture: run FMEA/DFMEA with suppliers, define reliability targets and burn-in requirements, and feed field failure data back into the next revision. Coordinate cross-functionally with design engineering, construction, commissioning, utilities/interconnection, safety, and sourcing so NPI schedules are integrated with campus delivery schedules. Keep suppliers honest: track readiness and risk with clear metrics, escalate early, and hold technical reviews that resolve issues rather than admire them. You may be a good fit if you have 8+ years of engineering experience in power electronics, electrical equipment, or industrial energy systems, with at least 4 years in an NPI, product development, or product engineering role that owned a product from prototype through production ramp. Direct, hands-on experience with at least two of: BESS, utility- or data-center-scale inverters, medium-voltage transformers or switchgear, UPS, STATCOM/power-quality equipment, or liquid cooling systems (CDUs, chillers, hydronics). Working knowledge of the relevant standards and how they get applied in qualification: UL 9540/9540A, UL 1741 and IEEE 1547, IEEE 2800, IEC 62477 / IEC 62909, IEEE C37 and C57 series, NFPA 70/855, UL 1778, and comparable IEC equivalents. Experience defining and executing structured qualification programs (EVT/DVT/PVT, FAT/SAT, type testing, reliability testing) and closing failures with disciplined root cause analysis and CAPA. Familiarity with supplier factory environments — production lines, test bays, quality systems — and the ability to assess a supplier's real readiness to ship at rate. Fluency in design-for-manufacturing and design-for-test principles and the supplier ECO/change-control process. Strong systems thinking: you can reason about how an inverter, a battery, a transformer, and a cooling loop behave together at a site, not just in isolation. Clear written and verbal communication, and comfort driving decisions across engineering, supply chain, and executive audiences. A bachelor's degree in electrical, mechanical, or power engineering, or equivalent experience. Willingness to travel 30–40% to supplier factories and data center sites, including internationally. Strong candidates may also have Experience with solid-state transformers, grid-forming inverters, E-STATCOM, or other emerging power-conversion equipment being introduced to data center or utility applications for the first time. NPI or product engineering experience at a hyperscaler, a large utility-scale developer, or a Tier-1 power equipment OEM. Background in grid interconnection studies, protection coordination, or power-system modeling (PSCAD, ETAP, PSS/E, or similar). Liquid cooling product introduction experience — CDU, rear-door heat exchanger, direct-to-chip, or immersion systems. Reliability engineering credentials (CRE, Six Sigma) or experience running HALT/HASS programs. Firmware and controls validation experience for power conversion equipment (inverter control loops, BMS, EMS, PLC/SCADA integration). Experience standing up or scaling new supplier manufacturing lines, including contract manufacturing and international sites. The annual compensation range for this role is listed below. For sales roles, the range provided is the role’s On Target Earnings ("OTE") range, meaning that the range includes both the sales commissions/sales bonuses target and annual base salary for the role. Annual Salary: $320,000 — $405,000 USD Logistics Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience Minimum years of experience: Years of experience required will correlate with the internal job level requirements for the position Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time.

How we're different We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills. The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences. Come work with us! Anthropic is a public benefit corporation headquartered in San Francisco. We offer competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.

Location: London & San Francisco Workplace: onsite THE OPPORTUNITY Apollo Research works with most frontier AI companies (OpenAI, Anthropic, Google, Meta, Thinking Machines and others) to test their models before deployment and collaborate on fundamental scheming research. Our coding agent security product, Watcher, is deployed in production and monitors billions of agent tokens per month across engineering teams at agent-building scale-ups and enterprises.  Security exists at Apollo to safeguard the trust our lab partners place in us and to enable that research. Our own team runs around 400 billion tokens a month through AI agents, which makes Apollo both a target and a testbed. We’re hiring Security Engineers to join the Infra & Security Team.  In this role, you will design, implement, and deploy the security controls that keep Apollo secure, and make the secure path the default path for everyone. You will build the security layer for a novel insider risk that didn't exist before. RESPONSIBILITIES Design, build, and operate Apollo's core security controls: identity and access management, infrastructure and cloud security, endpoint management, and incident response. Build paved roads that make the secure path the default, easy path Establish and advocate for security practices across Apollo, and build the organizational trust needed for people to adopt them, communicating security decisions and tradeoffs clearly along the way. Evaluate vendors and tooling, make build-vs-buy calls on security infrastructure, and assess vendor security posture before adoption. Lead major security projects end to end, from ideation through implementation and rollout. Collaboratively define and shape the security roadmap and priorities. KEY REQUIREMENTS Must-haves 5+ years in security roles in a hands-on technical capacity (not purely GRC/compliance). You'd need to be able to think structurally about threat modeling and failure modes. You need to be able to read code, understand infrastructure, and evaluate technical controls. Engineering mindset. You treat security as an engineering problem. You are capable of, and willing to, build custom solutions when the task demands it, rather than relying on 'glueing' together off-the-shelf tools. You prioritize automation and systems-level thinking to scale security, and you are comfortable leveraging AI to accelerate development. Direct experience with application security, cloud security, or product security. Ideally you’ve owned or significantly contributed to the security posture of an organisation that handles sensitive customer data. Influence without authority. You have a track record of building buy-in for security practices and being trusted by non-security people. Startup pace. You are excited about a fast-moving environment, comfortable with ambiguity and changing priorities, and willing to grind when it matters. Nice-to-haves Software engineering experience We would be excited to have candidates who have the one or more of these specialisations: Zero-trust architectures Sandboxing Detection engineering GRC engineering Incident response Endpoint management (Kandji, Jamf, or similar) Identity/access management Explicitly not required Deep AI/ML security or LLM-specific expertise Formal AI safety research background. We need security practitioners who can learn the AI safety context, not AI safety researchers who need to learn security. We want to emphasize that people who feel they don’t fulfill all of these characteristics but think they would be a good fit for the position, nonetheless, are strongly encouraged to apply. REPRESENTATIVE PROJECTS Zero trust migration: Design and deliver an incremental path from Apollo's current cloud architecture toward zero trust, including hands-on implementation and deployment reducing the blast radius if any single credential, device, or agent is compromised. Agentic SOC: Design and build an internal agentic SOC from scratch; automate triage and investigation of security alerts so detection coverage scales with Apollo's growing use of AI agents. Sandbox hardening: Review Apollo's sandboxing infrastructure; propose and implement changes that improve security while minimizing impact on researcher productivity. Third-party access review: Implement a lean, streamlined access review process for third-party software that people will actually use. Incident response: Lead an incident response effort end to end: containment, root cause, and the post-mortem that turns it into a durable fix. Pentesting tooling: Decide which agentic pentesting solution Apollo will use, and whether to build or buy. BENEFITS This role offers market competitive salary, equity, and competitive benefits. Salary: San Francisco : $214,000 – $280,000; London : £144,000 – £189,000. We will be looking to meaningfully raise salaries soon. Our engineers effectively have an unlimited token budget.

ABOUT THE TEAM The Infra and Security team is currently led by Rusheb Shah and consists of Glen Rodgers and Steven Lee. You will work closely with Security Researchers we’re hiring for as well as technical staff from the Scheming Research and Product team. You can find our full team here. ABOUT APOLLO RESEARCH The rapid rise in AI capabilities offers tremendous opportunities, but also presents significant risks. At Apollo Research, we're primarily concerned with risks from Loss of Control, i.e. risks coming from the model itself rather than e.g. humans misusing the AI. We're particularly concerned with deceptive alignment / scheming, a phenomenon where a model appears to be aligned but is, in fact, misaligned and capable of evading human oversight.  We work on the science of scheming, detection of scheming (e.g. building evaluations), and scheming mitigations (e.g. anti-scheming). We also work on control and monitoring research (see our scalable monitoring agenda). We work closely with many frontier AI companies, such as OpenAI, Anthropic, Google, Meta, Thinking Machines and others, e.g. to test their models and collaborate on the science of scheming. At Apollo, we aim for a culture that emphasizes truth-seeking, being goal-oriented, giving and receiving constructive feedback, and being friendly and helpful. If you're interested in more details about what it's like working at Apollo, you can find more information here. We also build a coding agent security product called Watcher that secures agent deployments in companies. Our goal is to reduce the probability of catastrophic incidents by securing coding agents, learning about their real-world risks, and publishing our research on how to build these control systems most effectively. Equality Statement: Apollo Research is an Equal Opportunity Employer. We value diversity and are committed to providing equal opportunities to all, regardless of age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex, or sexual orientation.

Location: London & San Francisco Workplace: onsite THE OPPORTUNITY We are building Watcher, a coding agent security product. Watcher is deployed in production and monitors billions of agent tokens per month across engineering teams at agent-building scale-ups and multinational enterprises. Every one of those deployments involves custom engineering: integrating with the customer's coding agents and security stack, running in their cloud or on-prem environment, and tuning monitors to their workflows. We are looking for a Forward Deployed Engineer to own that work end to end. You will be the technical face of Watcher to customers across the entire lifecycle: running technical evaluations and POCs with prospects, deploying Watcher into customer environments, building the integrations and custom capabilities they need, and providing white-glove support that turns early customers into long-term partners. You are an engineer first. When a customer needs something, your default is to build it, and then to work with the product team to decide what becomes part of the core product. This is truly a "start-up role." You will be one of the first dedicated customer-facing engineers, you will have significant say in shaping how Apollo deploys and supports Watcher, and you can earn more responsibility quickly. As we grow, this role can develop toward leading forward-deployed engineering, solutions architecture, or core product engineering, depending on your interests. KEY RESPONSIBILITIES Deployment and integration engineering (~40%) Own customer deployments end to end: cloud, on-prem, and self-hosted backends, from architecture discussion through production rollout. Build integrations between Watcher and customer environments: coding agent setups (Claude Code, Codex, Cursor), SIEM and security operations tooling, identity and access systems, CI/CD pipelines. Configure and tune monitors, policies, and permissions for each customer's workflows, and validate that monitoring quality holds on their real traffic. Debug issues in environments you don't control, often under time pressure, and drive them to resolution with the product team. Pre-sales and technical evaluation (~30%) Run technical evaluations and POCs with prospects: scope the pilot, deploy Watcher on their agent traffic, and demonstrate concrete value (caught failures, security coverage, developer experience). Serve as the technical counterpart to security and engineering leaders during evaluations: answer architecture and security questions, run demos on the prospect's actual use cases rather than canned examples. Work with our AI Security & Control Engineer on security questionnaires, architecture reviews, and customer pen-test support during procurement. Feed honest signal back into the team about why deals progress or stall technically. White-glove support and product feedback (~30%) Be the named technical contact for key customers. Own their escalations, incident communication, and feature requests. Build customer-specific capabilities where warranted, and drive the "should this be product?" conversation with the Engineering Manager and product engineers so one-off work compounds into the roadmap. Turn deployment experience into leverage: documentation, deployment tooling, and runbooks that make every subsequent deployment faster and less bespoke. Represent the voice of the customer in planning: you will know better than anyone what real security and platform teams need from Watcher. REPRESENTATIVE PROJECTS Land a lighthouse enterprise: Run a POC for a large enterprise with a strict security posture: scope the pilot with their security team, stand up a self-hosted backend inside their infrastructure, integrate with their SIEM, tune monitors on their traffic, and present results that convert the pilot into a production contract. Build a reusable deployment path: After your first several deployments, turn the bespoke steps into a repeatable, documented, partially automated deployment package (infrastructure templates, integration modules, validation checks) that cuts time-to-production for new customers by more than half. Ship a customer-driven capability into the product: Take a recurring customer request (e.g. a custom alert routing scheme or a new agent integration), build it for the customer who needs it, generalize it with the product team, and ship it as a core Watcher feature. Rescue a wobbly account: A customer's monitors are noisy, their engineers are annoyed, and their security lead is questioning the renewal. Diagnose the root causes of their traffic, retune the configuration, fix the underlying issues with the product team, and win back their confidence. JOB REQUIREMENTS Must-haves Strong engineering foundation. 3+ years building and shipping production software. You can work across the stack (Python and TypeScript primarily), read unfamiliar code fast, and are comfortable with cloud infrastructure, networking basics, and deployment tooling. You will regularly build under constraints you don't choose, in environments you don't control. Genuinely good with customers. You communicate clearly with both hands-on engineers and security leadership, you stay calm and constructive when something is on fire, and customers come away trusting you. This is not a tolerance requirement; you should like this part of the job. High agency and ownership. When a customer is blocked, you don't wait for a ticket to be routed. You find the problem, fix it or escalate it with a proposed solution, and follow through until it's resolved. Startup pace. You are excited about a fast-moving environment, comfortable with ambiguity and changing priorities, and willing to grind when it matters, including occasionally at customer-driven hours. Judgment on custom vs. core. You can tell the difference between a request worth building bespoke, a request that should become a product, and a request to push back on, and you can deliver that pushback to a customer gracefully. Strong written communication. Deployment docs, incident updates, and POC reports need to be clear and precise. Comfortable leveraging AI heavily for engineering and customer work, while holding the output to a high standard. Strong nice-to-haves Prior FDE, solutions engineering, or professional services experience, especially at a developer-tools, security, or infrastructure company. Experience deploying software into enterprise environments: on-prem, VPC deployments, SSO/identity integration, security reviews, procurement processes. Familiarity with the enterprise security stack (SIEM, DLP, endpoint tooling) and with how security teams evaluate vendors. Experience with coding agents as a power user or builder. You have used Claude Code, Codex, Cursor, or similar tools heavily, or built agent tooling yourself. Pre-sales exposure: you have run POCs or technical evaluations and know how to demonstrate value on a prospect's terms. Willingness to travel occasionally to customer sites. Explicitly not required Formal AI safety background. We need excellent customer-facing engineers who can learn the AI safety context. Sales experience or quota history.

ABOUT APOLLO RESEARCH The rapid rise in AI capabilities offers tremendous opportunities, but also presents significant risks. At Apollo Research, we're primarily concerned with risks from Loss of Control, i.e. risks coming from the model itself rather than e.g. humans misusing the AI. We're particularly concerned with deceptive alignment / scheming, a phenomenon where a model appears to be aligned but is, in fact, misaligned and capable of evading human oversight.  We work on the science of scheming, detection of scheming (e.g. building evaluations), and scheming mitigations (e.g. anti-scheming). We also work on control and monitoring research (see our scalable monitoring agenda). We work closely with many frontier AI companies, such as OpenAI, Anthropic, Google, Meta, Thinking Machines and others, e.g. to test their models and collaborate on the science of scheming. At Apollo, we aim for a culture that emphasizes truth-seeking, being goal-oriented, giving and receiving constructive feedback, and being friendly and helpful. If you're interested in more details about what it's like working at Apollo, you can find more information here. We also build a coding agent security product called Watcher that secures agent deployments in companies. Our goal is to reduce the probability of catastrophic incidents by securing coding agents, learning about their real-world risks, and publishing our research on how to build these control systems most effectively. Equality Statement: Apollo Research is an Equal Opportunity Employer.

Available Locations: Austin, TX Atlanta, GA Denver, CO Seattle, WA Washington, DC Application Deadline: December 16, 2026 Position Overview Cloudflare is looking for an Automation Specialist to transform how our global Data Center Security Compliance (DCSC) team operates. This critical role is part of the Infrastructure Operations organization, which is responsible for building, scaling, and running Cloudflare's data center and network infrastructure across 700+ sites worldwide. The DCSC team manages physical access control and compliance auditing across one of the most complex and distributed infrastructure footprints in the industry, spanning more than 105 vendor portals, hundreds of non-portal carrier-neutral and edge partner sites, and multiple regulatory frameworks including SOC 2, ISO 27001, FedRAMP, ISMAP, and IRAP. The operational burden of this work is substantial and largely manual: user lists are pulled by hand, access control lists are reconciled by eye, evidence packages are assembled ticket by ticket, and attestation cycles consume weeks of coordinator time every quarter. This role exists to change that. The DCSC Automation -Specialist will design, build, and operate AI-assisted and automated workflows that eliminate the most time-consuming manual work in the DCSC operating model, freeing compliance coordinators to focus on exception handling, stakeholder relationships, and regulatory judgment rather than data gathering and reconciliation. This is a builder role. You will interview the team to understand each workflow, identify the highest-leverage automation targets, and ship tooling that demonstrably reduces the time it takes to close a QAR cycle, produce an audit evidence package, or manage a batch of access provisioning requests. You will work in close partnership with the DCSC coordinators, and existing automation developers, and will own the DCSC operational tooling roadmap. Key Responsibilities Portal Automation & User List Extraction Browser Automation: Design and maintain automated scripts (Playwright, Puppeteer, or equivalent) that log into vendor data center portals, extract user access lists, and feed structured output into the DCSC Portal and comparison pipelines replacing manual portal-by-portal data collection across 105+ portals covering 338+ sites. Resilience & Coverage: Build fallback handling for portals that block or rate-limit automated access; document exceptions and maintain a coverage registry tracking automation status per portal. Scheduled Execution: Operationalize extraction jobs on a recurring cadence aligned to QAR and MAR cycles, with alerting for failures and drift. ACL Reconciliation & Diff Engine Automated Comparison: Build tooling that ingests portal-extracted user lists and compares them against the master Access Control List (ACL), automatically surfacing discrepancies: users present in a portal but absent from the ACL, users on the ACL without active portal access, and role or access-level mismatches. Exception-Only Output: Route confirmed discrepancies directly to pre-populated Jira tickets for human review and action, eliminating the need for coordinators to perform full manual review of every user record each quarter. Audit Trail: Ensure all comparison runs produce immutable, timestamped records suitable for SOC 2, ISO 27001, and FedRAMP evidence requirements. Attestation & Evidence Automation Attestation Module: Own and extend the attestation workflow within the DCSC Portal, including automated cycle triggering, manager notification, time-stamped confirmation capture, and exception escalation, replacing manual screenshot-based evidence gathering. Evidence Package Builder: Build automated pipelines that compile audit-ready evidence packages for SOC 2, ISO 27001, FedRAMP, ISMAP, and IRAP control cycles, pulling attestation logs, portal extraction results, diff reports, and correspondence into structured packages keyed to specific control IDs. GRC Alignment: Work directly with GRC counterparts to validate that automated evidence formats meet auditor and regulatory requirements before deployment. AI-Assisted Anomaly Detection & Triage Access Pattern Analysis: Implement LLM-based review passes over QAR cycle output to surface patterns warranting human escalation: former employees retaining access, access creep over time, dormant accounts, and anomalous role assignments across sites. Ticket Intelligence: Build automation that reads incoming Jira onboarding and offboarding tickets and generates structured, portal-specific action checklists reducing coordinator cognitive load and preventing missed steps across multi-portal provisioning workflows. Continuous Improvement: Monitor automation output quality over time, retrain or recalibrate models as portal structures change, and maintain a feedback loop with coordinators on false positives and missed detections. DCSC Portal Ownership & Tooling Roadmap Platform Stewardship: Own the DCSC Portal as the operational runtime for all automation and workflow tooling ensuring it remains stable, documented, and usable by coordinators without engineering support for day-to-day tasks. Roadmap Management: Maintain a prioritized backlog of automation opportunities, assessed by time savings, compliance impact, and implementation complexity; present quarterly progress and priorities to DCSC leadership. Documentation: Produce runbooks for every automation, ensuring that no operational capability lives only in one person's head or on a local machine. Desirable skills / Experience: Automation Engineering: Demonstrated experience building browser automation (Playwright, Puppeteer, Selenium, or equivalent) against real-world web applications, including handling authentication flows, dynamic content, and anti-bot mitigations. TypeScript Proficiency: Strong skills for scripting, data wrangling, structured file I/O, and API integration. Ability to write maintainable, documented code that non-engineers can operate. LLM Integration: Hands-on experience integrating LLM APIs (OpenAI, Anthropic, Google, or equivalent) into production workflows for classification, drafting, summarization, or anomaly detection tasks. Data Engineering Fundamentals: Comfort working with structured and semi-structured data at scale, diffing datasets, normalizing inconsistent formats, and producing clean outputs for downstream audit use. API & Workflow Integration: Experience building integrations with ticketing or ITSM systems (Jira preferred) via REST API, including automated ticket creation, status updates, and attachment handling. Systems Thinking: Ability to map an end-to-end manual workflow, identify the highest-leverage automation insertion points, and ship incrementally without waiting for a perfect solution. Workflow Archaeology: Comfortable extracting process knowledge from subject-matter experts through structured interviews turning tribal knowledge into documented, automatable workflows. Bias Toward Simplicity: Strong product intuition for the minimum viable automation that delivers real time savings, rather than over-engineering for edge cases. Compliance Awareness: Appreciation for the stakes of accuracy in a compliance context, understanding that an incorrect ACL diff or a missing evidence artifact has real audit consequences. Soft Skills: Communication: Able to explain automation design decisions and tradeoffs clearly to non-technical stakeholders including compliance coordinators and GRC partners. Ambiguity Tolerance: Vendor portals don't come with documentation. Workflows are passed down verbally. You need to be energized by figuring things out from scratch. Preferred Qualifications Experience with Cloudflare Workers or similar edge compute platforms Familiarity with GRC/compliance frameworks (SOC 2, FedRAMP, ISO 27001) at an operational level — not as an auditor, but enough to understand why evidence integrity matters RPA tooling experience (UiPath, Power Automate) as fallback for portals that defeat headless browsers Prior work in infrastructure operations, data center, or physical security environments Experience building internal tooling or developer-facing portals (not just scripts) Compensation Compensation may be adjusted depending on work location. For Colorado based hires: Estimated annual salary of $136,000 - $187,000. Washington (Kirkland), and Washington D.C. based hires: Estimated annual salary of $150,000 - $206,000.

Location: London & San Francisco Workplace: onsite THE OPPORTUNITY We are building Watcher, a coding agent security product. Watcher is deployed in production and monitors billions of agent tokens per month across engineering teams at agent-building scale-ups and enterprises. We are looking for a product engineer to build and scale Watcher end to end. This role includes backend and frontend components. You will own features across the full stack, from agent hooks and ingestion pipelines to monitoring dashboards and enterprise integrations. You can expect to  own features from customer conversation to production deployment. This is truly a “start-up role”: you will own big chunks of the product, make decisions fast, and ship at high volume. You will join a small team with significant ability to shape the product and tech, and you can earn more responsibility quickly. This is an individual contributor role but could lead to management responsibilities eventually, if desired. KEY RESPONSIBILITIES Ship product end to end (~45%) Feature development Design, build, and ship Watcher features across the stack: agent-side hooks and CLI tooling, ingestion and grading pipelines, real-time monitoring UI (Watcher Live), and the organization-wide Analyzer dashboard. Own features end to end, from ambiguous requirements to production: talk to users, scope the work, make the technical decisions, put that into production, and iterate based on usage. Build Watcher integrations:  We currently support Claude Code and Codex, but we’re planning on increasing our coverage to other coding agents, LLM gateways, and anywhere that could benefit from agent monitoring. Build the policy and configuration layer that lets security teams set org-wide guardrails for  engineers to operate safely within. Productionize research Turn monitoring research (new monitors, grading strategies, backtesting results) into production-ready product features. We are "our own customer": You will use the product you build every day. Infrastructure and scale (~35%) Design and operate backend systems that process large volumes of agent logs in real time. Own reliability: robust error handling, graceful degradation, and observability (logging, metrics, tracing, alerting). We should catch issues before customers do. Architect data models and storage that handle both high-throughput writes and complex analytical queries over historical trajectories. Retention policies have to fit highly sensitive customer data. Make sure Watcher is safe to deploy: Work with our AI Security & Control Engineer on tenant isolation, encryption, and access controls. Watcher touches some of the most sensitive data our customers have. Customer and integration engineering (~20%) Build and maintain integrations with the enterprise security stack, e.g. streaming monitoring alerts into SIEM systems and existing security operations workflows. Support flexible deployment models: cloud-hosted, on-prem, and local backends, so sensitive agent logs never have to leave customer control. Talk to customers, debug issues in their environments, and feed what you learn back into the roadmap. REPRESENTATIVE PROJECTS Secure a new frontier coding agent: Take an agent we don't yet support (e.g. Cursor) from zero to fully monitored. Build the hook/integration layer, normalize its trajectory format into our data model, validate monitor accuracy on real traffic, and ship it to customers. Build the real-time blocking path: Design the low-latency pipeline that lets monitors block dangerous actions (e.g. git push --force, secret exfiltration) before they execute, while keeping p95 latency low enough that developers don't feel it. Handle traffic spikes and partial failures gracefully. Ship an Analyzer capability end to end: Design and build an organization-wide view (e.g. failure trends over time, cross-session pattern detection) from data model through API to UI, based on what security teams actually need. Deploy Watcher inside locked-down enterprises: Build and document the self-hosted/on-prem deployment story so that enterprises with strict data requirements can run Watcher  inside their own infrastructure. JOB REQUIREMENTS Must-haves 4+ years building production software. You have shipped and operated real systems with real users, and you know what it takes to keep them reliable. Full-stack capability. You are strong on the backend (APIs, data pipelines, databases, cloud infrastructure) and productive on the frontend (modern web UI). You don't need to be world-class at both, but you must be able to own a feature across the whole stack. Our stack is primarily Python and TypeScript. High agency and ownership. You are willing to own big chunks of the product, make decisions fast with incomplete information, and be accountable for the outcome. You don't wait to be told what to do and have an accurate sense of the roadmap for the product. High output volume. You have used Claude Code, Codex, Cursor, or similar tools heavily to accelerate or have built agents or agent tooling yourself. Startup pace. You are excited about a fast-moving environment, comfortable with ambiguity and changing priorities, and willing to grind when it matters. Product sense. You can talk to users, translate vague requirements into concrete designs, and make good calls about what to build and what to cut. Strong nice-to-haves Previous work on developer tools, monitoring/observability systems, or security products. Watcher sits at the intersection of all three. Real-time or large-scale data processing experience (streaming pipelines, message queues, high-throughput log systems). Enterprise or on-prem deployment experience. Shipping software into environments you don't control is its own skill. Experience building LLM-powered applications, e.g. LLM-as-judge setups, evaluation pipelines, or familiarity with frameworks like Inspect. Early-stage startup experience. You have been employee 1-15 somewhere and know what it feels like to build a product with no playbook. Explicitly not required Formal AI safety background. We need excellent product engineers who can learn the AI safety context, not AI safety researchers who need to learn engineering. Management experience. This is an IC role, at least initially. Deep experience in every technology we use. We care about demonstrated ability to learn and ship, not checkbox familiarity with our exact stack. We want to emphasize that people who feel they don’t fulfill all of these characteristics but think they would be a good fit for the position, nonetheless, are strongly encouraged to apply. BENEFITS This role offers market competitive salary, equity, and competitive benefits. Salary: San Francisco: $222,000 – $290,000 London: £149,000 – £195,000.

Location: San Francisco; London We are hiring builders to define how people talk to, show things to, and hear from AI In 2026, we launched Computer, the defining product for the new era of agentic AI. We've scaled beyond the millions of people using Perplexity every day for research, shopping, investing and curiosity into a new paradigm of using AI to transform knowledge into action. The Multimodal team builds the experiences and infrastructure that move AI interaction beyond touch and text — realtime voice, vision, and the platform systems behind them. We own the full path from a user speaking into a device to an answer coming back: the realtime session infrastructure that connects clients to frontier audio models, the backend orchestration that routes, records, and supervises live sessions, and the SDK that powers voice and multimodal experiences across Perplexity's apps. As a backend engineer on Multimodal, you will design and scale the distributed systems that carry live voice sessions in production — and drive entirely new products at the intersection of voice, vision, and agents. WHY PERPLEXITY IS DIFFERENT - Craftsmanship. We build high quality, tasteful products targeting both the AI native and AI curious. - Ownership. You identify the problem, design the solution and ship it. - Entrepreneurship. We think like founders, act with urgency, and hustle to deliver for each other and our users. - Scholarship. Work among highly talented peers, pursuing knowledge and truth, upleveling ourselves, our teams, and our products. - Partnership. We amplify each others' strengths, break down silos, and give selflessly to help our colleagues deliver excellence. WHAT YOU'LL DO - Design, build, and scale the backend session-worker architecture that powers realtime voice: durable per-session workers, provider routing, and stateful streaming over gRPC. - Own distributed-systems problems end-to-end — session lifecycle, crash recovery, reconnection and replay, multi-region deployment, and graceful degradation under real production load. - Build provider-agnostic streaming protocols from our backend to the Rust SDK that powers voice across every client stack. - Drive new products and initiatives in voice and multimodal AI from problem definition through technical design, implementation, and launch. - Build the orchestration layer that lets live voice models delegate work to tools, agents, and long-running tasks — safely, asynchronously, and at scale. - Partner closely with SDK, client, infrastructure, and model teams; work across the stack when the product demands it, from backend services to client-facing APIs. WHAT WE'RE LOOKING FOR - 4+ years of professional software engineering experience building backend or distributed systems. - Strong experience in Rust, Python, or Go (we work primarily in Rust and Python). - Experience designing and operating production distributed systems: streaming RPC (gRPC or similar), stateful services, message-driven architectures, and failure recovery. - Solid understanding of cloud infrastructure — deploying, scaling, and operating services on AWS or equivalent. - Strong product judgment and the ability to translate user problems into simple, effective technical solutions. - Genuine interest and adoption of AI products and willingness to learn quickly. NICE TO HAVE - Experience with realtime media systems: voice, audio streaming, WebRTC, or low-latency transport. - Full-stack range — comfort building end-to-end, from backend services through client SDKs or web frontends. - Experience integrating LLMs, speech models, or computer vision into production systems. - Experience with agent frameworks, tool-calling architectures, or sandboxed execution environments. - Time spent at a fast-growing startup or on a high-ownership engineering team. OUR MISSION Perplexity’s mission is to power curiosity. Curious people are the people who drive change in the world. Driving change is a continuous cycle of learning, building, and integrating. Learn: curious people constantly learn new things by asking more. They question the status quo in their own expertise and they constantly learn outside of it. Research is essential to them and never ending. Build: curious people make and create things, to show the world their new answers to problems no one else ever questioned. They take action on what they’ve learned. Makers need tools to create their products, their companies, their reality. Integrate: they must interact with the world as it is to drive change and adoption. True leaders do not simply build something and hope. They must have armies of agents and workers who can constantly work in millions of small ways. Repeat. For curious people this is a cycle that never ends.

Location: UK, London Workplace: OnSite Here at Humanoid, we believe in a future where robots amplify human potential. That’s why we’ve set out on a mission to build the world’s most capable, commercially-scalable, and safe humanoid robots. We’re bringing that mission to life with HMND‑01 - our rapidly developed humanoid platform being deployed in real industrial environments - and we’re growing the team to take it even further. ABOUT THE ROLE We are looking for a Senior Hardware Test Engineer to own the test methodology for HMND‑01’s hardware components, robot subsystems, and complete humanoid robots. You will be the engineer who decides what “good” looks like — from a single actuator on the bench to a full robot walking through an integration sequence. This is a hands-on, technical leadership role. You will design test methods, run them yourself on early prototypes, and partner closely with the test automation team, Manufacturing Engineering, Production Operations, and Supply Chain Quality as we move from EVT toward production. You’ll be the hardware voice that shapes what gets measured on the line, at what tolerance, and why — without owning the QC routine or rig build, which sit with Production Ops Quality and Manufacturing Engineering respectively. KEY RESPONSIBILITIES 1. TEST METHOD DEFINITION - Component-Level Methods: Define functional, performance, and stress tests for individual hardware components — actuators, sensors, electronics, structural parts — including pass/fail criteria and required data capture. - Subsystem Testing: Design integration tests for major robot subsystems (arms, hands, legs, torso, head) covering kinematic accuracy, repeatability, load behavior, and thermal response. - Whole-Robot Testing: Define and execute system-level tests for full robot assemblies, including end-to-end motion sequences, balance, manipulation tasks, and failure-mode behavior. 2. HANDS-ON TEST EXECUTION - Prototype Bring-up: Be the first engineer to put hands on each new hardware revision, characterizing performance against design intent and feeding findings back to the design team. - Failure Analysis: Investigate failures during testing, work with hardware engineers to root-cause issues, and verify fixes. - Test Documentation: Capture methods, results, and learnings in a way that the rest of the organization can repeat and trust. 3. AUTOMATION SUPPORT - Test Automation Inputs: Translate manual test methods into specifications for the automation team. Decide which tests can be automated and which must remain manual, and why. - Tooling: Specify and prototype custom test fixtures, jigs, and instrumentation needed to execute your methods reliably during prototype and bring-up work. - Data: Define what each test must capture so that automated runs produce results comparable to your manual baseline. 4. PRODUCTION TEST — IN PARTNERSHIP WITH MANUFACTURING ENGINEERING AND PRODUCTION OPS - Requirements for Line Rigs & Jigs: Provide the technical requirements for production test jigs, fixtures, and test beds — what they measure, at what tolerance, what data they need to capture, and the pass/fail criteria. Manufacturing Engineering owns rig design, build, and commissioning; you review designs and sign off on whether they actually verify what they’re meant to verify. - In-Process Verification: Define the checks at each stage of assembly that confirm components and sub-assemblies have been built correctly before they move to the next station, including required measurements and rework paths for failures. - Test Evidence & Traceability: Define what each production test must capture so that results, measurements, and pass/fail outcomes are written to the production database, linked to the serial number of the unit under test — every shipped robot has a complete and queryable build and test history. - System-Level Acceptance: Define final-product acceptance tests — performance envelopes, functional gates, and sign-off criteria for a robot leaving the line. 5. QUALITY & DESIGN FEEDBACK LOOP — IN PARTNERSHIP WITH SUPPLY CHAIN QUALITY AND PRODUCTION OPS QUALITY - Component Performance Characteristics: Define the system-level performance characteristics that incoming parts must meet. Supply Chain Quality translates these into incoming inspection criteria and supplier qualification plans, and runs the inspection process. - Root-Cause Partnership: Partner with Production Ops Quality on root-cause analysis when line failures trace back to component behavior or system design, and feed findings back into engineering. - Closed Loop with Design: Treat test data as a closed loop with design — surface trends from production into design reviews so the product gets better, not just the process. QUALIFICATIONS Must-Have: - Experience: 5+ years in hardware test engineering, with hands-on testing of complex electromechanical systems — robotics, automotive, aerospace, or similar. - Test Methodology: Strong grasp of test theory, test design, and pass/fail criteria definition. You can write a test spec that another engineer can execute without follow-up questions. - Mechanical: Solid understanding of mechanical design principles, common core components (gears, bearings, actuators), measurement tools (calipers, micrometers, load cells, encoders), and technical drawings including GD&T basics. - Electrical: Comfortable reading schematics, using a multimeter and oscilloscope, and reasoning about basic power and signal integrity. - Production Fluency: Familiarity with hardware production operations — flow, takt, work instructions, traveler documentation — enough to collaborate effectively with Manufacturing Engineering and Production Ops without trying to own their work. - Tooling: Experience with test and task tracking systems (Jira, X-Ray, TestRail, or similar). - Matrix Operating Style: Comfortable influencing test stations, rigs, and equipment design through clear requirements and tight partnership, not through ownership. - Mindset: Systems thinking — you naturally see how a problem at the component level can manifest as a behavior at the full-robot level. Nice-to-Have: - Robotics experience, especially with serial-link manipulators or legged systems. - Hands-on test rig and fixture design experience (mechanical and/or electrical) — useful for speaking the same language as Manufacturing Engineering on rig requirements. - Python (or similar) for ad-hoc data analysis and lightweight test automation. - CAD (SolidWorks/Fusion/NX) for sketching test fixtures. - Familiarity with ROS2. - Experience with embedded systems and field buses such as CAN or EtherCAT. - Experience with industrial automation equipment (servos, gateways, sensors, PLCs). - Knowledge of statistical quality control fundamentals (SPC, MSA) — for working effectively with Quality on test data interpretation. WHAT YOU'LL BE TESTING - Actuators (motors, gearboxes, encoders, drivers) - Robot manipulators and end-effectors - Legged subsystems and balance behaviors - Power and battery systems - Full humanoid robot assemblies WHAT WE OFFER - Meaningful time off to rest and recharge: 23 days of annual leave (accrued), 15 days of paid sick leave, and paid company holidays. - Fully funded private healthcare for UK employees, with broad provider access, virtual and in‑person care, and strong mental health and serious illness support. - Equity included–we believe builders should share in what they build. - Pension scheme with a total 8% contribution (5% employee, 3% employer) on full earnings. - Free daily breakfast, catered lunch, and snacks in‑office. - Collaboration with top‑tier engineers, researchers, and product experts in AI and robotics. - Freedom to influence the product and own key initiatives.
