We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure.\nBuilt by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.\nListed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.\nThe Role\nWe are looking for a Senior Full Stack Engineer to build how developers and AI agents access our agentic web infrastructure. This role is based in our New York office, hybrid with the NYC team.\nOur APIs are used by millions of developers and the AI agents acting on their behalf. The team owns the main API gateway, the customer platform (keys, usage, teams), identity and enterprise SSO, and the public interfaces to our product: the SDKs, CLI, MCPservers and other tools developers and agents use. You'll work closely with product, design and engineers across our R&D.\nIn this position, your responsibility will be to:\nDesign and ship features end to end, from the interface to the services and data behind it\n\nBuild and improve the API gateway: high traffic, low latency, reliable\n\nTurn usage, billing and team data into fast, usable interfaces: tables, charts, filters and forms\n\nShape the self-serve journey from signup through activation\n\nBuild and operate identity and team access in production: OAuth and OIDC, role-based access, SAMLSSOand SCIM, on providers such as Auth0, Okta, WorkOS or Clerk\n\nControl who gets which features, with feature flags for staged rollouts and entitlements after rollout\n\nImprove the public interfaces developers and agents use: the SDKs, CLI, MCPservers and docs\n\nYou may be a good fit if you:\nHave 5+ years of full-stack engineering on customer-facing products or high-throughput APIs, in any mix of frontend and backend\n\nAre strong in backend engineering, ideally in Python. Go, C++ or C with some Python experience also fits\n\nHave built and operated latency-sensitive, high-QPSAPIs: caching, async work, queues, retries and rate limiting, including long-running jobs and webhooks\n\nHave shipped production UI with a modern frontend framework such as React, Next.js or TanStack, ideally in TypeScript\n\nHave built data-heavy interfaces such as tables, charts and filters that stay fast\n\nAre effective in a mature, user-facing system: you have joined a complex codebase, ramped up fast, shipped safely under real traffic, and been on-call for it\n\nHave strong product and design sense, for interfaces and for APIs\n\nSee your work through from design to production, explain trade-offs clearly to partners, navigate ambiguity, and use AI tools in how you build\n\nStrong candidates may also:\nHave led a project or mentored others\n\nHave taken a product from 0 to launch\n\nHave built API-key issuance and lifecycle\n\nHave built MCPservers or tools for AI agents\n\nHave worked on billing or usage metering with Stripe, Metronome, Orb or similar\n\nPay Transparency\nWe offer competitive compensation and benefits packages. Actual compensation will be determined based on job-related factors, including experience, skills, qualifications, the level at which the candidate is hired, and geographic location, consistent with applicable law.\nBase Compensation Range\n$147,200—$224,300 USD\nBenefits & Perks:\nCompetitive compensation\nCareer growth and learning opportunities\nFlexibility and ownership\nCollaborative and innovative culture\nOpportunity to work on impactful AI projects\nInternational environment and talented teams\nWhat's it like to work at Nebius:\nFast moving - Bold thinking - Constant growth - Meaningful impact - Trust and real ownership - Opportunity to shape the future of AI \nEqual Opportunity Statement:\nNebius is an equal opportunity employer.
