Join us and help build the platform engineers turn to ship AI products. THE ROLE The largest, most demanding enterprises run on Baseten, and they bring exacting requirements for how people, services, and agents access the platform. This is the founding role for our identity and authorization team within enterprise engineering. You'll own the identity and access layer of the Baseten platform: the authorization model, credential systems, and admin experiences that enterprise IT teams use to govern access for organizations like Harvey, HubSpot, and Notion. You'll design and build Baseten's fine-grained authorization system from the ground up to support the workflows customers depend on today while giving them cleaner, more precise ways to manage access as the platform grows. Authorization at Baseten requires low-latency permission checks at high request volume, consistent contracts and behaviors across the product suite, and strong security guarantees for mission-critical, highly regulated workloads.   EXAMPLE INITIATIVES Recent and upcoming work in this area: - Fine-grained authorization for users, service accounts, and agentic workloads: per-resource permissions at the organization, team, and workload scope to support both common workflows and complex enterprise access policies - Programmatic authentication allowing high-compliance customers to connect service principles securely via short-lived, workload-based credentials - Agent credentials that grant an agent exactly the access it needs for the given task and nothing more - Enterprise identity lifecycle including single sign-on, SCIM provisioning, and per-organization session expiry policies - Admin controls for centralized visibility, auditability, and governance over credentials, roles, and access   RESPONSIBILITIES - Lead identity and authorization projects from problem definition and technical design through implementation, launch, and iteration. - Design authorization and credential models that support critical user workflows today and can be safely extended as the platform evolves. - Partner with product, design, and customer-facing teams to turn enterprise security requirements into durable technical solutions. - Establish engineering practices for quality, security, observability, and operational ownership. - Provide technical leadership and mentorship as the team grows.   REQUIREMENTS - 4-5+ years of experience building production backend systems, including hands-on design and implementation of a product authorization system: per-resource or per-object permissions, relationship-based access control, a policy engine, or a fine-grained authorization system in the style of Zanzibar, OpenFGA, SpiceDB, or Cedar. - Demonstrated end-to-end ownership: you've taken a system from first design through implementation, production rollout, and iteration with users. - Experience developing and operating multi-tenant systems at scale, where authorization checks sit in the request path and latency and consistency matter. - Comfort working across the full stack, from product and application code to cloud and Kubernetes infrastructure.   NICE TO HAVE - Experience with Python and Go. - Experience running an OpenFGA, SpiceDB, or similar deployment in production, beyond a proof of concept. - Working knowledge of OAuth, OIDC, and SCIM at the protocol level. BENEFITS - Competitive compensation, including meaningful equity - (U.S. only) 100% coverage of medical, dental, and vision insurance for employee and dependents - Flexible PTO policy including company wide Winter Break (our offices are closed from Christmas Eve to New Year's Day!) - Paid parental leave - Fertility and family-building stipend through Carrot - (U.S. only) Company-facilitated 401(k) - Exposure to a variety of ML startups, offering unparalleled learning and networking opportunities.

Location: United States; Denver; Seattle; Austin; New York; Boston; San Francisco Workplace: Remote Most companies treat support as a cost center. We treat it as an engineering challenge and a product opportunity. Support Operations Engineering is an engineering function inside ClickHouse’s Support Services organization. We build the systems that decide how customers get help from the moment they describe their problem to the moment it’s resolved. This role will help shape how Support Services, RevOps, GTM, and core Engineering teams collaborate on customers. This is not a tools team. About a third of our work directly supports the support organization. The rest is building experiences and systems that change how ClickHouse works with its customers in more effective, streamlined ways. WHAT YOU WILL BE DOING You’ll design and build the systems that sit between ClickHouse’s customers and the teams who serve them. The work is varied by design, and you’ll move between problem types as priorities shift: - Intelligent routing and decision systems. Software that decides where work should go and who should handle it, weighing many signals at once, and is built to adapt as the business scales. - AI-powered customer experiences. Customer-facing and internal experiences that understand what someone needs, recommend the best next step, and know when to hand off to a human. - Internal platforms and tooling. Applications that give Support, RevOps, and GTM teams the leverage to work faster and more accurately, built to production standards. - Integrations and data flow. Connections across Salesforce, live chat, incident management, Slack, GitHub, and more, so workflows and data move cleanly between systems. - Automation and observability. Systems that remove repetitive work, surface what’s breaking, and give teams confidence in what they’re running. Across all of it, you’ll partner with core Engineering to ship to production, and own what you build: code review, testing, monitoring, and continuous improvement. WHAT YOU BRING ALONG: - 3–5 years building and shipping full-stack software in production, with tools like TypeScript/JavaScript, Node.js, and React (or comparable) - Experience developing with APIs, webhooks, and integrations between distributed systems - Hands-on experience close to support: as a support or technical support engineer, or by building tools or integrations for a support, CS, or RevOps team - Confidence with Git and safe, version-controlled deployment workflows - The ability to translate operational needs into solutions that non-engineers can follow - A shipper’s mindset: self-driven, curious, and comfortable owning a problem end-to-end in a remote, globally distributed team - Comfort using AI tools day to day in how you build, with a clear sense of where to trust them BONUS POINTS: - Experience building LLM-powered features in production (routing, retrieval, evaluation, or observability) - Salesforce platform experience (Apex, LWC, Flows, custom objects) or certifications; if you don’t have it, the appetite to get there quickly - Support and incident tooling: Pylon, incident.io http://incident.io, PagerDuty, Zendesk, Slack APIs, GitHub APIs - Experience with ClickHouse or other analytical databases - Experience in an early-stage or greenfield environment, or embedded in a support, RevOps, or business-systems function PERKS - Flexible work environment - ClickHouse is a globally distributed company and remote-friendly. We currently operate in over 25 countries. - Healthcare - Employer contributions towards your healthcare. - Equity in the company - Every new eligible team member who joins our company receives equity. - Time off - Flexible time off in the US, generous entitlement in other countries. - A USD$500 Home office setup if you’re a remote employee. - Global Gatherings – We believe in the power of in-person connection and offer opportunities to engage with colleagues at company-wide offsites.

Location: London Workplace: OnSite Company Description We’re http://checkout.comCheckout.com http://Checkout.com. You might not know our name, but companies like eBay, Spotify, Klarna, Uber, and Sony do, because we’re behind many of the digital experiences you use every day. We are where the world checks out, enabling over 10 billion transactions yearly for more than one billion global shoppers. Whether you want to book a holiday, order food, renew a subscription, or check out online, there’s a good chance our tech powers the payments behind the scenes. Our platform helps the most ambitious businesses deliver effortless digital experiences, at scale. If you want to do career-defining work, you’ve come to the right place. We move fast, think globally, and believe great teams are built by hiring exceptional people with conviction, curiosity, and the desire to make an impact. With 20 offices across six continents and London as our HQ, we’re shaping the future of fintech – and we’re just getting started. As a Staff Engineer (Payment Processing) at Checkout.com http://Checkout.com, you will set the technical direction for our Gateway, Routing and Payout platforms. Every payment and payout we process passes through these systems, from the merchant's API request to the routing decision that sends it to the right acquirer, payment method or payout rail. Correctness matters on every transaction, and small changes in availability, latency or routing quality show up directly in our merchants' approval rates and revenue. This is a role for engineers who are energised by scale and by the hard trade-offs that come with it: latency budgets on the authorisation path, failure domains and blast radius, consistency and idempotency across regions, and the operational reality of running critical infrastructure around the clock. You will operate as a force multiplier across multiple teams - shaping architecture, raising the engineering bar, and turning ambiguous, business-critical problems into designs that can be delivered incrementally. We're looking for individuals with deep technical judgement, strong ownership, and a pragmatic approach to breaking big problems into smaller iterations that deliver value continuously. How you'll make an impact - Own the architecture of high-throughput, low-latency distributed systems, defining the service boundaries, data models and integration patterns that let them scale by an order of magnitude - Design for resilience from first principles - redundancy, graceful degradation, backpressure, idempotency and recovery - so that partial failures never become customer-facing outages - Set and defend the non-functional requirements that matter: availability targets, latency percentiles, throughput ceilings, data durability and recovery objectives - Lead the hardest technical decisions end to end, from problem framing and design review through to production rollout, migration and decommissioning of what came before - Drive operational excellence by improving observability, alerting, capacity planning, load and chaos testing, and incident response, and by closing the loop on the root causes you find - Raise the engineering bar across teams through design reviews, code review, pairing and mentorship, growing the senior engineers around you - Partner with product, platform and other engineering teams to sequence delivery, remove blockers and keep multi-team programmes aligned on a single technical direction - Make pragmatic build-versus-buy and refactor-versus-rewrite calls, and communicate the reasoning and trade-offs clearly to both engineers and senior leadership Experience and qualifications - Significant experience building and operating distributed backend systems in production, with a track record of technical leadership across multiple teams - Demonstrable experience designing for high throughput and low latency, and a strong intuition for where systems break under load - Deep understanding of resilience patterns in distributed systems: idempotency, retries and backoff, circuit breaking, queueing and backpressure, consistency and failure modes - Strong proficiency in either .NET or Java, and the ability to write clear, production-ready code that others can maintain - Experience with event-driven and streaming architectures, and with relational and non-relational data stores at scale - Hands-on experience with cloud-based application development (we use AWS & Azure), containers, orchestration and infrastructure as code - Experience owning production systems on call, with a strong sense of ownership for observability, monitoring and incident response - Experience leading complex migrations or re-architectures of live, business-critical systems with no loss of availability or data integrity - Excellent communication skills, able to influence without authority, write clear design documents, and express technical trade-offs to engineering and non-technical audiences alike Nice-to-haves - Experience in payments, financial services or another domain with strict correctness, auditability or regulatory requirements - Experience with multi-region or active-active architectures, including data replication and failover strategies - A history of mentoring engineers into senior and staff-level roles Additional Information Bring all of you to work We create the conditions for high performers to thrive, through real ownership, fewer blockers, and work that makes a difference from day one. Here, you’ll move fast, take on meaningful challenges, and be recognized for the impact you deliver. It’s a place where ambition gets met with opportunity, and where your growth is in your hands. We work as one team, and we back each other to succeed. So whatever your background or identity, if you’re ready to grow and make a difference, you’ll be right at home here.

Location: Limassol Cyprus Workplace: OnSite Job Title: Staff/Lead SDET Engineer (Test Automation Platform) Product: Total Battle Total Battle is a massive MMO 4X strategy game available on mobile and web, uniting millions of active players. As our product and engineering teams scale, we are shifting our testing paradigm: automated testing must become a daily, self-service engineering tool rather than a bottleneck owned by a dedicated team. We are looking for a Staff/Lead SDET to take technical ownership of our internal test automation tooling and make this vision a reality. Why this role exists Your core mission is to empower product QA teams. You won't write tests; you will build the tools, APIs, and abstractions that allow QA engineers (with basic Python & OOP skills) to independently create checks, manage test states, run tests in CI/CD, and diagnose failures. - The Product Teams own the tests. - You own the tooling layer that makes their work possible. [https://app.ashbyhq.com/api/images/user-content/55591132-5874-4888-add0-f14f70025dca/2aa3a273-986b-4c05-b6a2-27fee33e607f/image.png] 💡 Core Focus Areas: 1. Client Testing Tools: UI scenarios, method/component checks across Android, WebGL, and (soon) iOS. 2. Server Integration: Component testing tools built over existing Python clients, SDKs, and product testability capabilities.(Note: We aren't starting from scratch. We need a visionary who can assess our existing solutions, define a target architecture, and evolve them incrementally). What You’ll Work On - Drive Technical Strategy: Define the roadmap for QA tooling, evolve its architecture, and personally implement key solutions. - Build the Platform: Develop domain APIs, fixtures, and state-preparation tools for integration/component testing over existing SDKs. - Enhance Client Automation: Extend client UI automation and enable sub-UI checks for specific client methods. - Unify Execution: Ensure local and CI execution follow a predictable, unified path across Android and WebGL. - Create Diagnostics: Build clear diagnostic tools to help QA engineers easily distinguish between product, test, tooling, and infrastructure failures. - Cross-Team Collaboration: Translate recurring QA needs into product testability requirements and establish technical contracts with client/backend teams. - Evangelize & Mentor: Drive adoption of your tools through pilots, solid documentation, and feedback loops.

Location: San Francisco, CA Workplace: OnSite ABOUT US Sierra is the leading platform for customer-facing AI agents, working with many of the world's biggest brands — including The GAP, Rocket Mortgage, SoFi, Sutter Health, and SoftBank — to transform how they serve customers and grow their businesses. We are primarily an in-person company based in San Francisco, with growing offices across North America, Europe, and Asia. We are guided by a set of values that are at the core of our actions and define our culture: Trust, Customer Obsession, Craftsmanship, Intensity, and a commitment to balancing Family along the way. These values are the foundation of our work, and we are committed to upholding them in everything we do. Sierra was co-founded by Bret Taylor https://www.linkedin.com/in/brettaylor/ and Clay Bavor https://www.linkedin.com/in/claybavor/ who first met while working together at Google over 20 years ago. Bret currently serves as Chairman of the Board of Open AI. Previously, he was co-CEO of Salesforce and CTO of Facebook. Clay spent 18 years at Google, where he most recently led Google Labs. WHAT YOU'LL DO The agent must collect and use a card number but can never see it. This work sits across four hard technical domains: payments, security, real-time voice, and LLMs. Voice is the core challenge. A caller speaks or types a card number in a live, low-latency audio stream, and the digits must never reach the model, while the model stays on the call. Sierra owns every system that touches card data, and one small team owns it end to end across three workstreams: Platform, Product, and Safety & Integrity. Customers keep their own telephony and payment gateways. Payments is live in production for some of the largest consumer enterprises, on a platform that handles hundreds of millions of calls a year. The platform is certified to PCI DSS Level 1. - Build real-time card capture for voice: intercept keypad and spoken digits in a live audio stream, upstream of the agent runtime in a network-segmented environment, while the LLM stays live on the call. Make it work across every telephony provider and protocol Sierra supports. - Build and extend the tokenization platform: agents receive and send short-lived tokens, and the platform swaps a token for the real value only when it calls the customer's payment gateway. - Own the payments egress control plane: every destination for card data is approved, versioned with the agent release, and enforced by infrastructure below the application, not by convention. - Make payment actions correct: an at-most-once action primitive in the Agent SDK, validated amounts and items, and monitoring that compares what the agent said about a payment with what really happened. - Keep card data out of places it should not be: deterministic detection in the agent's hot path that catches what general-purpose models miss. No LLM, including any we build ourselves, ever sees a plaintext card number. - Make payments self-serve: one payments API across Agent Studio, the Agent SDK, and Ghostwriter, Sierra's agent-building agent; gateway middleware that developers write against tokens; and support for single-tenant and customer-cloud deployments. Any team can add payments to an agent without a payments engineer in the loop. - Grow the platform beyond cards: extend tokenization into a privacy vault for all PII. WHAT YOU'LL BRING - 5+ years building backend, platform, or infrastructure systems, with a track record of shipping and operating high-reliability services in production. - A deep security instinct. You design as though every component will eventually be compromised, and you reason naturally about blast radius, least privilege, and making bad states impossible rather than reacting to them. - Rigor about correctness under failure: retries, idempotency, at-most-once behavior, and clear handling of timeouts and unclear results from external systems. - Fluency in a systems language (we use Go) and comfort owning critical systems end to end, from design through production and on-call. - Range and ownership. You like a small team with broad scope, you build clean abstractions over messy external systems, and you're never satisfied solving a problem once per customer. - Clear communication. You can explain a design or a risk to other engineering teams and to non-engineers. - Degree in Computer Science or a related field, or equivalent professional experience. You don't need payments experience. The engineers who built this platform came from backend, infrastructure, and security work, not payments. We care more about how you build correct, secure systems than about the word "payments" on your resume. EVEN BETTER… - Real-time or streaming systems: voice, telephony, media, or low-latency pipelines. - Applied cryptography and key management, network isolation, egress control, or cloud security. - Platforms other engineering teams build on, such as APIs, SDKs, and self-serve developer services. - Deployments into customer-owned clouds or single-tenant environments. - Customer-facing technical work, such as architecture reviews with customers. - Setting technical direction on ambiguous, high-stakes problems. - Payments, fintech, or another sensitive-data domain such as healthcare or identity. OUR VALUES - Trust: We build trust with our customers with our accountability, empathy, quality, and responsiveness. We build trust in AI by making it more accessible, safe, and useful. We build trust with each other by showing up for each other professionally and personally, creating an environment that enables all of us to do our best work. - Customer Obsession: We deeply understand our customers’ business goals and relentlessly focus on driving outcomes, not just technical milestones. Everyone at the company knows and spends time with our customers. When our customer is having an issue, we drop everything and fix it. - Craftsmanship: We get the details right, from the words on the page to the system architecture. We have good taste. When we notice something isn’t right, we take the time to fix it. We are proud of the products we produce. We continuously self-reflect to continuously self-improve. - Intensity: We know we don’t have the luxury of patience. We play to win. We care about our product being the best, and when it isn’t, we fix it. When we fail, we talk about it openly and without blame so we succeed the next time. - Family: We know that balance and intensity are compatible, and we model it in our actions and processes. We are the best technology company for parents. We support and respect each other and celebrate each other’s personal and professional achievements. WHAT WE OFFER We want our benefits to reflect our values and offer the following to full-time employees: - Flexible (unlimited) paid time off - Medical, dental, and vision benefits for you and your family - Life insurance and disability benefits - Retirement plan dependent on country of employment - Parental leave - Fertility and family building benefits - Lunch, as well as delicious snacks and coffee to keep you energized when working onsite - Discretionary benefit stipend giving people the ability to spend where it matters most - Free alphorn lessons These benefits are further detailed in Sierra's policies, may vary by region and employment type, and are subject to change at any time, consistent with the terms of any applicable compensation or benefits plans.
