Senior/Tech Lead Backend Engineer (Managed Kubernetes)

Nebius Managed Kubernetes (mk8s) mission is to grow the Nebius cloud platform by providing a Kubernetes-native way to run AI systems with high efficiency and low operational overhead. With a single click, it provides a Kubernetes cluster on top of Nebius services for compute (VMs) and networking. In 2026, the service is scaling 10× and is expected to manage customer workloads across tens of thousands of GPU servers in more than 10 data centers.

You will lead the mk8s Core team, one of three mk8s teams. The Core team owns the API, the core of the service control plane, cluster autoscaling, platform integrations, and running k8s add-ons.

At Nebius, team leads are hands-on. We expect you to be a senior or staff engineer now (or earlier in your career). You will start as an individual contributor to gain context, then take on managerial responsibilities.

In this position, you will be responsible to:

Lead by example. Set the quality bar by spending a significant portion of your time on IC work: writing and reviewing code, leading projects, and participating in on-call rotation, incident mitigation, and post-incident analysis.

Manage 4–8 mid-to-senior engineers. Provide context, coach, and give regular feedback.

Maintain the technical vision for your area of responsibility.

Collaborate with the Product Manager and Service Owner to shape product vision and plans.
