About the role

Nebius is seeking a Senior Software Engineer to help build Nebius Serverless AI, a GPU-native platform for deploying inference endpoints, batch jobs, and AI workloads without managing infrastructure. This is a senior, high-ownership role on a fast-evolving service. You will own the architecture of the components you ship, drive design decisions, and raise the engineering bar through code reviews and design reviews. The work is end-to-end—from cold-start latency in the runtime to the API contracts developers integrate against. You will work from our offices in Amsterdam or London on a hybrid basis.

Responsibilities

Re

Design and build core components of the Serverless platform: the control plane, scheduler, runtime, autoscaler, and the APIs customers integrate against.
Tackle the hardest engineering problems: cold-start latency, GPU scheduling under contention, multi-tenant isolation, fair-share quotas, and edge routing.
Set the technical direction for your areas: drive architecture decisions, write design docs, and align the team behind the chosen approach.
Raise the engineering bar through code reviews, design reviews, and mentoring; contribute to a culture of excellence.
Run the service like an SRE: define SLOs, build observability, lead incident response, and ensure postmortems drive platform improvements.
Work directly with customers on architecture reviews, performance escalations, and production problems that don’t fit a template.
Partner closely with Product, GTM, and infrastructure teams to translate customer needs into a coherent technical roadmap.
