The Role

Nebius is hiring a Senior Software Engineer to design, build, and own backend systems that power metrics, monitor large-scale infrastructure, and develop a comprehensive infrastructure maintenance platform. This role requires strong production experience, sound system design judgment, and the ability to operate and improve critical services.

Your responsibilities will include:

• Design and build services and agents that provide deep visibility into large-scale server fleets and data center engineering systems
• Evolve metrics, aggregation, and alerting pipelines, with a focus on signal quality and reliability
• Design and operate maintenance and remediation systems that enable safe, predictable fleet-wide changes and keep infrastructure healthy
• Investigate production incidents hands-on, including on-host Linux debugging, and drive root-cause fixes
• Collaborate closely with hardware, networking, and data center operations teams to improve reliability

What we expect you to have:

• 5+ years of professional software engineering experience
• Strong production experience with Python and Go, or the ability to ramp up quickly
• Solid Linux fundamentals and comfort debugging live systems
• Ability to write reliable, maintainable code and dig into complex, ambiguous problems
• Experience building and operating production systems at scale

It will be an added bonus if you have:

• Ubuntu experience, including internal tooling and packaging workflows (e.g., building Debian packages)
• CCNA (Cisco Certified Network Associate) or equivalent networking experience

Key employee benefits: 

• Health insurance: 100% company-paid medical, dental, and vision coverage for employees and families.
