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. \n About the Team \nWe are a fast-growing, distributed team of engineers and product professionals based primarily in Europe. The team brings together strong backend, frontend, product, and business expertise, with a shared focus on building impactful, scalable systems. \nWhile we initially started without deep specialisation in AI/ML, the team has rapidly grown into the space-demonstrating strong ownership, curiosity, and the ability to tackle complex technical challenges. \nTechnology & Environment \nOur work is deeply integrated with a broader cloud and infrastructure ecosystem. We primarily use Go and Python to build and scale backend systems and collaborate closely with teams focused on areas such as infrastructure, observability, billing, and AI research. \nThe platform continues to evolve from a lightweight integration layer into a more comprehensive system, including custom infrastructure, optimisations, and deeper control over performance and reliability. \nWhat We’re Working On \nScaling distributed systems: Expanding our platform to handle significantly increased workloads while maintaining performance and reliability \nImproving reliability: Enhancing system stability and uptime to meet enterprise-grade expectations \nOptimising AI performance: Continuously adapting to new models, hardware, and runtime improvements \nExpanding platform capabilities: Building beyond inference into broader AI infrastructure, including data pipelines, customization, and advanced usage features \nWe expect you to have:\n5+ years of professional software development experience.\nStrong software engineering skills (we mostly use Python and Go).\nProficiency in contemporary software engineering approaches, including CI/CD, version control and unit testing.\nExperience with developing web services.\nA commitment to maintaining extreme rigor in all job-related activities.\nNice to have:\n Previous experience working with language models or other similar NLP technologies.\nA track record of building and delivering products (not necessarily ML-related) in a dynamic startup-like environment.\nStrong engineering skills, including experience in developing large distributed systems or high-load web services.\nOpen-source projects that showcase your engineering prowess.\nWhy It’s Interesting \nThis is an opportunity to work at the intersection of distributed systems, cloud infrastructure, and applied AI, tackling real-world scalability challenges and shaping how companies adopt AI in production environments. \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.
