Forward Deployed Engineer, Ecosystem

Nebius is leading a new era in cloud infrastructure for the global AI economy. 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.

Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.

Listed 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.

Nebius builds the infrastructure serious AI teams run on — GPU clusters, inference runtimes, agent development environments, data pipelines — all of it purpose-built for the most demanding AI workloads. What we are now building is the ecosystem function that ensures the best AI companies choose to build on us, integrate with us, and stay. 

As a Forward Deployed Engineer, Ecosystem, you will sit at the intersection of solution architecture and hands-on engineering. You assess how partner products actually work on our stack, define the reference architecture for each integration, build the working prototype that proves it, and translate what you find into product requirements that shape what Nebius ships next. 

• →6+ years of hands-on engineering experience in AI application development, ML systems, or AI infrastructure
• →Deep working knowledge of the AI developer stack — LLM APIs, inference runtimes, orchestration frameworks, vector databases, RAG architectures, agentic pipelines — built through shipping, not reading
• →Hands-on experience with agentic frameworks such as LangChain, LangGraph, CrewAI, AutoGen, or equivalent
• →Strong Python programming skills and comfort prototyping end-to-end AI systems quickly
• →Experience defining reference architectures and technical patterns — not just implementing them
• →Proven ability to move from idea to working prototype fast — you have shipped meaningful things under time pressure and found it energizing
• →Experience building integrations across APIs and developer platforms — you understand where the complexity actually lives
• →Comfortable working across both external partner engineering teams and internal Nebius product and engineering teams simultaneously
• →Strong technical communication — you can explain architecture decisions and integration findings to a founding CTO and a non-technical partner lead in the same day 

Fast moving - Bold thinking - Constant growth - Meaningful impact - Trust and real ownership - Opportunity to shape the future of AI
