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.

The role

We are looking for a Senior Hardware Support Engineer to own production hardware reliability across large-scale, mission-critical data center environments. This role operates at the intersection of hardware engineering, operations, and vendors, ensuring fleet stability, rapid root cause identification, and continuous improvement of server and platform reliability.

You will act as a senior escalation point for complex hardware and firmware issues affecting production systems, driving investigations from symptom to root cause and coordinating resolution across engineering, vendors, and on-site teams. The role requires strong analytical thinking, structured problem-solving methodology, and deep hardware expertise in high-density, performance-critical infrastructure environments.

Your responsibilities will include

Leading root cause analysis for complex hardware and firmware failures across production fleets

Aggregating recurring problems and error patterns to identify systemic reliability issues

Acting as the senior escalation point for hardware-related incidents impacting availability or performance

Coordinating with vendors to drive timely diagnostics, RMAs, firmware fixes, and corrective actions

Partnering with internal engineering teams to validate fixes and prevent recurrence

Performing hardware and firmware validation before fleet-wide rollout

Driving structured incident investigations using established IT problem management methodologies

Supporting on-site teams with technical coordination during critical hardware events

Improving hardware observability, failure tracking, and reporting processes

Contributing to long-term hardware reliability strategy and fleet-wide stability improvements

What we expect you to have

Strong hands-on expertise with server hardware in data center or large-scale production environments

Proven experience performing root cause analysis of hardware and firmware failures

Deep understanding of server components (CPU, memory, storage, networking, power, BMC) and failure modes

Experience working directly with hardware vendors and engineering teams to resolve production issues

Structured problem-solving skills using formal IT or incident management methodologies

Strong analytical capabilities and ability to interpret logs, telemetry, and error patterns

Experience coordinating technical activities with on-site operations teams

Ability to manage multiple concurrent investigations with production impact

Clear written and verbal communication skills in cross-functional environments

It will be an added bonus if you have

Experience in GPU-dense, AI, or high-performance computing environments

Exposure to firmware lifecycle management and large-scale rollout validation

Familiarity with Linux-based production systems and infrastructure tooling

Experience improving fleet-wide hardware reliability metrics at scale

Working conditions

Onsite work in the Birmingham Alabama Data center.

Participation in incident escalations for production-impacting events

Key employee benefits

Comprehensive medical, dental, and vision coverage

401(k) plan with company contribution

Flexible paid time off

Paid parental leave

Professional development support

Compensation

$125,000 – $180,000 per year plus annual performance-based bonus.
