About Nebius
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.
Responsibilities
•Design and implement new functionality in YTsaurus core (C++) with production reliability in mind.
•Build and evolve platform-level capabilities: platform architecture and operating model—multi-cluster growth, shared primitives, and a consistent experience that scales with new teams and use cases.
•Improve end-to-end platform experience for internal (and external-facing) users: APIs, guardrails, debugging workflows, and automation.
•Own production quality: incident response / on-call rotation, root cause analysis, and turning learnings into durable fixes.
Requirements
•5+ years of software engineering experience.
•Strong C++ skills (you'll write core code).
•Working knowledge of Python and/or Go (you don't have to be expert, but should be comfortable navigating them).
•Experience developing and/or operating high-load, distributed services.
•Production mindset: ability to use SSH, read logs/metrics/traces, and debug distributed systems behavior.
•Solid CS fundamentals: algorithms, data structures, concurrency basics.
Nice to have
•Experience with Big Data systems (YTsaurus/Hadoop/Spark/ClickHouse/Kafka-like ecosystems).
•Experience with multi-tenant platforms, schedulers, resource isolation, quotas, and reliability engineering.
•Strong performance engineering skills (profiling, lock contention, latency/throughput tradeoffs).
Conditions
•Competitive compensation
•Career growth and learning opportunities
•Flexibility and ownership
•Collaborative and innovative culture
•Opportunity to work on impactful AI projects
•International environment and talented teams
•Fast moving - Bold thinking - Constant growth - Meaningful impact - Trust and real ownership - Opportunity to shape the future of AI
