Senior Software Engineer (Capacity and Quota Management)

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.

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.

The role:

We are looking for a Senior Software Engineer (Capacity and Quota Management) to join the team building the Capacity and Quota Management control plane — the system that decides who gets compute, when, and how much.

• Amsterdam, Netherlands; Berlin, Germany; United Kingdom

Idle GPUs are waste. Overallocated ones are a contract you can't keep. Our platform consists of two core components: a capacity reservation engine managing guaranteed GPU reservations and their lifecycle, including rebalancing and auto-reclamation logic; and a Quotas Control Plane that manages quotas across all Nebius services, handles customer quota requests, and runs the algorithms that distribute resources. Both are exposed through APIs that give external customers, internal users, and downstream services visibility and control over their limits.

This is a high-ownership role. You will define how Capacity and Quota Management matures, from the technical foundations to the tradeoffs that outlast any single feature.

We expect you to have:

• 5+ years of professional software engineering experience
• Strong knowledge of Python or willingness to quickly become productive with our technology stack
• Experience building distributed backend systems and microservice architectures
• Understanding of distributed transactions, consistency models, and reliable asynchronous workflows
• Strong communication and ownership mindset

Applicants must be authorized to work in the country in which they apply and will be required to provide proof of employment eligibility as a condition of hire.

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
