О компании и продукте

• 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.
• We’re looking for a Software Engineer with strong C++ expertise to join the team building and operating Nebius Data Platform — a distributed storage and a processing platform that acts as the company’s “source of truth” and the backbone of many internal (and some external) products.

Задачи

• We’re looking for engineers who combine strong systems skills with product sense : understanding who uses the platform, why certain capabilities matter, and making pragmatic trade-offs to maximize impact
• On our team, engineering work is expected to be connected to real users and outcomes — you’ll regularly align with internal stakeholders, clarify requirements, and help drive prioritization
• 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
• Example projects
• Roll out sharded YTsaurus masters (incl
• Kubernetes operator support) and build automatic balancing of metadata across master cells (consensus groups) to remove control-plane bottlenecks and unlock 10–100x cluster growth
• Make CHYT interactive SQL faster and more predictable at high load via performance work like data-skipping / min-max-style indexes and improved execution introspection
• Turn Orchestracto into a platform product by defining the building blocks, developer experience, and governance for how teams create and share workflows
• Scale and harden Parquet-on-S3 for native YTsaurus workloads by tackling replication/movement, consistent lifecycle semantics, and master-server metadata optimizations for performance and reliability
• Design and ship complete, trustworthy audit trails for data changes (who/what/when) across heterogeneous storage and compute paths
• Tech stack
• Core: modern C++ (C++20, async + multithreaded primitives)
• Services & tooling: Go and Python (microservices, utilities, integration tests)

Требования

• 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

Будет плюсом

• 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)
• We conduct coding interviews as part of the process
• Benefits & Perks
• 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
• What's it like to work at Nebius
