This role involves hands-on engineering, including coding, code reviews, and project leadership, alongside managing 4-8 engineers. The team focuses on the mk8s service control plane, API, cluster autoscaling, and platform integrations, crucial for scaling AI systems on the Nebius cloud platform. Responsibilities include setting quality standards, providing technical vision, collaborating with product management, and driving outcomes like optimizing control plane performance for large-scale GPU node management and improving resource utilization through autoscaling. The ideal candidate has 8+ years of experience, excellent Golang skills (or willingness to learn), and expertise in technical project leadership. Experience with team management and Kubernetes administration is a plus.

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.

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.

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.

Maintain the technical vision for your area of responsibility.

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

Examples of outcomes you could drive as a Team Lead

Optimize the service control plane to create and manage 20K GPU nodes in a single Kubernetes cluster, enabling a major contract for the company.

Integrate cluster autoscaling approaches (e.g., Karpenter) to improve resource utilization and support seamless auto-upgrades.

Provide a Kubernetes-native way to use local disks to reduce disk I/O bottlenecks for AI training and inference, improving efficiency.

Deliver managed Layer 7 load balancers to reduce operational overhead for customers.

8+ years of professional software engineering or management experience

Excellent knowledge of Golang, or you are ready to quickly switch to this programming language

Expertise with

Multi-month technical projects

Tech leading engineers
