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.\nAbout the Product \nToken Factory is focused on building a next-generation platform that enables companies to seamlessly integrate AI into their products and workflows. Our vision is to create a powerful, open, and scalable alternative for deploying and managing AI systems-making advanced AI infrastructure more accessible to both fast-growing startups and large enterprises. \nWe work with a wide range of customers, from AI-first companies to established technology organisations, helping them run AI workloads reliably at scale. Our goal is to become a leading platform for high-performance AI inference, delivering predictable latency, strong reliability, and the ability to scale to meet demanding production needs. \nCustomer feedback plays a central role in how we build-our development process is highly iterative and closely aligned with real-world use cases. \nAbout the Team\nThe Models Team is responsible for onboarding state-of-the-art (SOTA) open-source models into Nebius TokenFactory, including models such as DeepSeek V4 Pro, GLM 5.1, Kimi K2.6, and Minimax M2.7. A major focus of the team is serving large-scale AI models efficiently and reliably in production.\nTo achieve this, we work on advanced inference and systems optimization techniques, including:\n\nCache-aware routing\nNUMA-aware deployments\nKV-cache offloading\nDisaggregated serving architectures\nAutoscaling with high-speed model loading over InfiniBand / RoCE\nThe team maintains and extends forks of leading inference frameworks such as vLLM and TRT-LLM. We have deep expertise in production-scale model serving and regularly support the Solutions Architects team on the most demanding customer PoCs.\nTo operate efficiently at scale, we invest heavily in tooling and automation. \nExamples include:\n\nPerformance, quality, and smoke-testing frameworks\nHyperparameter optimization for inference framework configurations\nGibberish detection systems\nAutomated rollout pipelines for inference framework upgrades\nDiagnostics and observability tooling\nTraffic replay systems\nAutomated search for optimal serverless deployment configurations\nWe collaborate closely with model builders, open-source communities, Nebius Cloud teams, and hardware vendors to continuously improve our serving infrastructure.\nThe team is highly goal-oriented and outcome-driven, with a strong focus on delivering results rather than following rigid processes.\n\nTeam Structure\nWe are currently a team of eight engineers distributed across Europe, with members based in the Netherlands, the United Kingdom, Germany, and Latvia.\nOur workflows are optimized for remote collaboration. At the same time, we meet in person every one to two months at one of our locations to work together, brainstorm new ideas, and plan upcoming milestones.\nWhile many team members joined without extensive AI/ML experience, we have rapidly developed strong expertise in large-scale model serving and AI infrastructure.\nTechnology\nOur work is deeply integrated with the broader cloud and infrastructure ecosystem. We primarily use Go and Python to build and scale backend systems. We collaborate closely with teams working on cloud infrastructure, observability, reliability, fault tolerance, and platform engineering. The challenges we solve sit at the intersection of distributed systems, high-performance computing, and modern AI infrastructure.\nWe expect you to have:\nExperience serving LLMs in production\nStrong Python and/or Go programming skills\nExperience designing and operating highly scalable, highly available distributed services\nNice to have:\nContributions to vLLM, SGLang, TRT-LLM, or NVIDIA ecosystem open-source projects\nDeep understanding of KV cache management, speculative decoding, and quantization\nExperience with LLM evaluation frameworks\nHands-on experience with performance benchmarking and optimization\nDeep understanding of Kubernetes\nFamiliarity with distributed serving architectures and autoscaling\nKnowledge of InfiniBand, RoCE, or high-performance networking\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.
