Senior Software Engineer (Capacity and Quota Management)

The role:

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

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
