Location: New York, NY ABOUT CONSENSYS Consensys Incorporated is an independent blockchain infrastructure company, spun out of Consensys Software Inc. — one of the world's leading blockchain technology companies and the primary development organization behind the Ethereum ecosystem. We build and operate neutral, institutional-grade blockchain infrastructure that connects banks, asset managers, custodians, and financial market infrastructures to digital asset networks, meeting the non-negotiable standards of institutional finance: privacy, scalability, resilience, security, and regulatory readiness. Headquartered in Miami, Florida, and operating across the US, Europe, and Australia, Consensys Incorporated launched as an independent entity in September 2026 and is building the team to match its ambition. WHY THIS ROLE EXISTS We build and operate blockchain infrastructure for financial market infrastructure: settlement, custody and clearing institutions that put real value on the networks we run. We have signed clients with production dates this quarter and a platform standing on its own for the first time. Our pipeline of banks, custodians and market operators is growing faster than we can work it properly. You are the first hire on the Business Development team. You own the pipeline data and act as the coordination layer between prospects, engineering and leadership. You also make sure that what we promise in a sales conversation matches what we can deliver. When someone asks where a deal stands, what a client actually asked for, or whether a commitment is real, you're the person with the answer. WHAT YOU'LL OWN - Building pipeline with financial institutions: banks, custodians, broker-dealers, asset managers and market infrastructure providers. You work out who to approach, find the right person in each institution, and get the first meeting. - Account research before every conversation. You should know a prospect's settlement stack, where their collateral and liquidity problems are, what they've said publicly about tokenization, and who else they're talking to. Nobody should walk into a meeting cold. - Qualifying opportunities against what we actually sell: access, execution, interoperability and network engines, plus forward-deployed engineering engagements, managed hosting, interop settlement and sequencer services. That means working out whether there's a real budget, a real owner, a real timeline and a real problem we solve, and saying so early when there isn't. - Supporting live deal cycles, including discovery notes, meeting prep, follow-ups, RFP and RFI responses, security questionnaires and due-diligence packs. Institutional sales cycles are long and documentation-heavy. You keep them moving. - Pipeline and CRM discipline. Stages, next steps and close dates should reflect reality, and the forecast should hold up when someone questions it. - Market and competitive intelligence. Enterprise post-trade vendors don't publish their pricing, so what we know about it comes from conversations. You collect it, organize it and make it useful for pricing and positioning. - Translating between two worlds. Our buyers speak repo, collateral, DvP, cut-off times and operational risk. Our engineers speak sequencers, finality and nodes. You need to be fluent enough in both to bring back an accurate account of what the client asked for. - Outbound materials and messaging, working with Marketing and Product on one-pagers, case narratives, event follow-up and sequences that sound like they were written by someone who understands the client's business. - Events and ecosystem presence, including industry conferences, working groups and partner channels where institutional decision-makers show up. - Capturing client feedback for Product. What prospects ask for, what makes them hesitate and why deals stall should all reach the roadmap in a structured way. - Using AI in the work every day for research, account mapping, first drafts and meeting prep, held to the same bar for accuracy as anything else sent to a client. TWO LINES SIT OUTSIDE THIS ROLE AND YOU'LL WORK WITH BOTH CONSTANTLY: - Solutions and forward-deployed engineering own technical scoping, architecture and delivery commitments. You bring them in at the right moment with the right context, and you never promise a date or capability they haven't agreed to. - Legal and Finance own contract terms, pricing approvals and commercial structure. You make sure deals reach them clean and early, not the week before signature. WHAT WE ARE LOOKING FOR - 2–4 years in B2B tech sales, business development, or a client-facing role at a financial institution, fintech or market infrastructure provider. - Working knowledge of how institutional finance operates: trade lifecycle, clearing and settlement, custody, collateral. You don't need to be a post-trade expert, but you need to follow the conversation and ask good questions. - Real curiosity about onchain infrastructure and tokenized assets, and the ability to explain why it matters to a treasury or operations buyer without resorting to hype. - Strong written communication. Your emails, notes and summaries are clear, short and accurate. - Organized and persistent. Deals here take quarters, not weeks. You keep threads alive without being a nuisance. - Commercially sharp. You can tell interest from intent, and you'd rather disqualify a deal early than carry it on hope. - Comfortable in a company that is young and still building. The playbook is being written now, and you'll help write it. - Direct. This team has a low tolerance for polish over substance. Say the hard thing early, and say it kindly. - Coachable and collaborative. You want feedback, you act on it, and you make the people around you more effective. USEFUL, NOT REQUIRED - Experience selling into, or working at, a bank, custodian, CSD, exchange or clearing house. - Familiarity with Ethereum, EVM networks or permissioned blockchain deployments. - Exposure to repo, FX, stablecoins or tokenized treasuries/RWAs. - Experience with enterprise procurement: RFPs, vendor due diligence, InfoSec reviews. WHAT THIS ROLE IS NOT - Not a volume-dialing SDR seat. We'd rather have ten well-researched conversations than a thousand generic touches. - Not someone who overpromises to book a meeting. Our buyers remember. - Not someone who waits to be told what to do next, or who doesn't ask why an account matters. - Not someone who needs to be the loudest voice in the room. Listen first, then bring the insight. - Not a solutions-engineering role. You need to be credible technically, but you aren't expected to architect deployments. WORKING AT CONSENSYS We are a fully remote, globally distributed company. We hire the best people wherever they are, work asynchronously, and judge each other on impact rather than hours or location. We offer competitive compensation, meaningful equity, and the chance to work on genuinely open source software at the frontier of web3. Consensys is an equal opportunities employer.

We recently raised a $100M Series C, valuing the company at $2B, led by Meritech and Sapphire with participation from Greenoaks, Craft, Abstract, and Audacious. WorkOS powers enterprise features for many of the fastest-growing AI companies, including OpenAI, Cursor, and Perplexity, Sierra, and Plaid. As AI reshapes software, WorkOS is at the frontier of Human and Agent Authentication, Identity, and Access Control helping companies answer a new critical question: who are your agents, and what are they allowed to do? Our fast-growing customer base includes hundreds of modern software companies building the next generation of enterprise-ready products. ABOUT THE SECURITY PLATFORM TEAM The Infrastructure Security team provides and supports the primitives that enable engineering to securely build applications and meet compliance obligations, while abstracting away the underlying complexity for the best possible developer experience. Our work centers on workload identity and authorization: how internal applications authenticate to each other and to the services they depend on, and how that access is granted and enforced. We're replacing static secrets with short-lived identity credentials, bringing identity-based authentication to the services engineers use every day, and unifying how authorization is managed across the company. We're a platform engineering team with a security mission. We measure success by the security outcomes we enable and by how much engineers enjoy building on what we ship — the secure path should be the easiest path. WHO WE'RE LOOKING FOR - A platform builder. You love building infrastructure that other engineers rely on every day, and you sweat the developer experience details that make adoption effortless. - Fluent in service-to-service auth. You know authentication and authorization deeply: JWTs, X.509 certificates, and when to reach for each. - A systems thinker. You reason carefully about bootstrapping, circular dependencies, availability, and failure modes, especially for infrastructure that everything else depends on. - A pragmatic migrator. You know that shipping the primitive is half the job. You can drive adoption across many teams, meet them where they are, and retire the legacy path. - A strong partner to engineering. You build trust with engineers by understanding their priorities and making security frictionless. - Excited about AI. You're embracing AI and automation to scale platform work and reduce toil. - Curious and humble. You ask the basic questions, enjoy untangling complex systems, and bring others along with you. RESPONSIBILITIES - Build workload identity infrastructure. Make short-lived identity credentials a default part of every application's runtime environment, in partnership with application platform owners. - Bring identity-based authentication to internal services. Work with the owners of major internal dependencies to support identity certificates, make them the golden path for newly onboarding applications, and drive migration of existing ones. - Eliminate static secrets. Replace all static passwords and service tokens with short-lived identity credentials, and build identity-authenticated egress proxies and API abstractions that inject and automatically rotate managed secrets for the external dependencies that still require them. - Unify authorization. Build a single interface and framework through which authorization policies are centrally managed and enforced. QUALIFICATIONS - 5+ years of experience in software engineering, with a focus on security-related platform, infrastructure, or distributed systems. - Strong working knowledge of secrets management, fine-grained authorization, and workload identity systems. - Familiarity with the Kubernetes ecosystem and authentication/authorization technologies such as JWTs, X.509 certificates, PKI, cert-manager, SPIFFE/SPIRE, and OPA. - Experience building and operating production infrastructure that other teams depend on, with attention to availability and failure modes. - Proven ability to drive cross-team adoption of platform capabilities or lead large-scale migrations.

Experience with distillation, speculative decoding, EAGLE, Medusa, multi-token prediction, or related inference acceleration methods. Experience supporting agentic workloads involving tool calling, structured outputs, streaming APIs, high concurrency, and multi-step orchestration. Familiarity with CUDA or Triton; the role does not require kernel engineering to be the candidate’s primary specialization. Contributions to open-source projects such as vLLM, SGLang, TensorRT-LLM, FlashInfer, LMCache, PyTorch, Triton, Ray, or KServe. Implementation experience with cache-aware request routing, PDD, or WideEP, including diagnosing communication bottlenecks and load imbalance. Familiarity with GPU communication libraries and interconnects, such as NCCL, NVLink, InfiniBand, or RoCE.

Location: San Francisco, CA 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 Design at Anthropic sits at the intersection of craft, research, and product intuition. Design systems is a growing team working on products that millions of people use daily, and on interactions that don't have established conventions yet. Our work shapes how people experience AI: whether Claude feels like a tool or a collaborator, whether it earns trust or erodes it. We partner closely with engineers and researchers, often designing around capabilities that are emerging in real time. That means staying close to the models, prototyping rapidly, and being comfortable with ambiguity. We care deeply about the details that make something feel polished, trustworthy and human. We ship fast and learn in the open. We'd rather get something in front of users and iterate than wait for perfection. The Design Systems team exists to define and elevate the language of our UI and core interactions. Every Claude product, from claude.ai to Claude Code, shares one system, including the guidance Claude itself follows when it generates UI. You would be joining an early-stage team, working with design engineers and product designers across the company. You may be a good fit if you: Are as comfortable designing on canvas tools as you are building and prototyping within the product, and prefer to ship in days, not months. Have worked on design systems that balance simplicity with creative flair to produce beautiful products out of the box. Care about the smallest details as much as the big picture, from a pixel to how the whole app fits together. Make the people around you better through sharp, kind feedback and low ego. Get up to speed quickly and can make an impact on projects already in motion. Key responsibilities Design and evolve the system, from foundations (colour, type, spacing, icons, tokens, theming) to components like menus, dialogs, sidebars and the chat composer. Design the expressive layer as a system, not one-offs: motion, illustration and icons that are brand and system at once. Make the system legible to Claude as well as people: the guidance, metadata and evals that show whether Claude uses it correctly. Partner with product teams: help designers and engineers apply the system well, and feed recurring gaps back into the system. Prototype in code and ship: land changes in the design-system package alongside engineers, using Claude Code in your own practice. Minimum qualifications Strong visual and interaction craft. Experience building or working on a design system. Experience with design tokens, theming and accessibility standards. Fluency in whichever tool gets an idea across fastest, from Figma to code. Preferred qualifications Experience building products at the highest level of craft. Has shipped voice or other beyond-the-screen work, with native mobile instincts. Has designed an icon set, illustration style or motion system used across products. Experience defining evals, lint rules or automated checks for UI quality. 8+ years of product design experience. 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.

Location: Remote (US) Infrastructure Engineer (DevOps) About the company Hi, we're Ondo Finance. Our mission is to provide institutional-grade, blockchain-enabled investment products and services. We have both a technology arm that develops decentralized finance technology, and an asset management arm that creates and manages tokenized funds. We were the first company to tokenize exposure to US Treasuries, and have since expanded into several other assets. We are also focused on incubating protocols that can support both tokenized real-world assets and traditional crypto. Founded by folks from Goldman Sachs Digital Assets Team, we're backed by some of the best investors in the world including Founders Fund, Coinbase Ventures, Pantera Capital, Tiger Global, and more. We are currently the leaders in the space in terms of AUM and are well capitalized to continue growing the firm. We're fully remote, with team members across many countries.

Responsibilities * Collaborate with development teams to build reliable financial services for our customers. * Help the team build and improve release processes, continuous integration, and deployment automation. * Extend application monitoring and alerting. * Participate in an on-call rotation together with infrastructure engineers and developers. * Troubleshoot issues with user-facing and internal services, and debug production incidents. Requirements * Genuine curiosity and desire to learn new technologies and break things. * Hands-on Kubernetes experience: you can deploy, inspect, and debug workloads, even if you've never run a cluster yourself. * Understanding of operating systems, especially Linux internals. * Experience with "infrastructure-as-code" or "infrastructure-as-data" approaches to infrastructure management. * Understanding of the GitOps approach to application management. * Experience with the Prometheus stack or another monitoring solution. Nice to haves * Experience building infrastructure in a major cloud provider (AWS, Google Cloud, or Azure). * Programming ability in Go, Python, or another modern, widely adopted language. * Experience running stateful workloads in production, not only stateless services. Our tech stack AWS, GCP, Azure | Terraform | Kubernetes, Flux | Prometheus, Grafana, Datadog What we offer * Competitive compensation including salary, future token rights, and/or equity (according to your preferences) — we're well-funded and believe that great talent deserves great compensation * Full benefits (medical, vision, and dental) and flexible vacation policy (PTO) * Small remote-first team across many countries — you'll be an early team member helping shape our vision, culture, and design practices * A+ colleagues — our team includes alumni from: Goldman Sachs, Blackrock, Two Sigma, Bridgewater, SpaceX, AWS, Meta, Google, Pinterest, McKinsey, Circle, Uniswap, Phantom * Best-in-class investors — we are proud to be backed by leading crypto experts and VCs, including Pantera Capital, Founders Fund and Coinbase Ventures
