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 Software Engineer to build the event-processing pipelines and services that turn Nebius product usage into revenue.\nYou will work on systems that process a continuous stream of usage events, where correctness and failure recovery matter as much as throughput. The output is money: a silently dropped or double-counted event is a real financial error.\nUsage of every Nebius product arrives as a stream of events. Our pipelines and services ingest, validate, enrich and price it in near real time, and deliver the results to invoicing, reporting and customer-facing account management.\nIn this role, you will:\nBuild stateful streaming pipelines that compute billed consumption in near real time.\nDevelop and operate Go services that ingest usage events, move data between our storage systems and deliver consumption data to users through usage APIs and billing data exports.\nGuarantee correctness under failures: idempotency, exactly-once processing and reconciliation.\nOperate transactional storage, persistent queues and change data capture under high throughput.\nBuild reusable streaming infrastructure rather than solving each use case independently.\nImprove the reliability, scalability, latency and observability of the billing platform.\nTake end-to-end ownership of your systems: design, implementation, reliability and deployment.\nWe expect you to have:\nStrong software engineering fundamentals.\nProfessional experience building and operating backend, streaming or data-intensive systems.\nThe ability to reason about consistency and data correctness under failures.\nExperience with databases, messaging systems or event-processing platforms.\nThe ability to investigate unfamiliar systems and solve problems without an obvious predefined solution.\nThe ability and willingness to learn the team's technology stack.\nIt will be an added bonus if you have:\nExperience with a stateful stream-processing framework such as Apache Flink or Kafka Streams.\nExperience designing streaming pipelines.\nGo development experience.\nExperience operating services in Kubernetes.\nTechnology stack\nGo, Python\nApache Flink\nYDB\nYTsaurus\nMessaging and event-streaming systems\nKubernetes\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. We are committed to fostering an inclusive and diverse workplace and to providing equal employment opportunities in all aspects of employment.
