Senior Site Reliability Engineer (DevTools)

About the Position

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.

We're an SRE team within DevTools, looking for someone ready to help maintain and grow our systems. We run 25k builds a day in TeamCity, store 100 TB of artifacts in Artifactory, and work with a massive monorepo in GitLab - comparable in scale to what you'd find at FAANG companies. We modify GitLab and build our own TeamCity plugins to give users a product that meets their needs. We're also experimenting with AI - we have our own RAG setup and are figuring out how to operate in the age of agents. Our goal: understand users' problems and requests, define metrics that capture the problem, improve those metrics, and verify that the user's problem is actually gone.

Responsibilities

• Improving services based on user feedback
• Building fault-tolerant, self-healing architecture
• Finding ways to speed up our systems and reduce user friction
• Modifying well-known closed- and open-source solutions
• Supporting our users

Requirements

• A combination of SRE and SWE experience (for us that's a 50/50 split). Our code is in Java/Kotlin, Go, Python, and Ruby
• An understanding of what's happening under the hood in Unix-like systems and the JVM
• A passion for improving the user experience
• The ability to adapt quickly on the fly in a fast-changing environment

Nice to Have

• Experience in Platform Engineering
• Experience operating GitLab (or another VCS) and TeamCity (or another CI system)
• Experience with Spring and operating Java monoliths

We Offer

• 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
