About the role

Original posting from Nebius

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 building our L3 Support Line from scratch to serve as the datacenter center of expertise for servers, firmware (BIOS/BMC), and deep Linux diagnostics across APAC.

This is a senior technical role focused on deep investigations, cross-site pattern detection, and driving permanent fixes with R&D and ODM vendors. You will turn complex incidents into scalable solutions and elevate L1/L2 capabilities through strong technical enablement.

Your responsibilities will include: 

Deep Technical Investigation (Primary Focus)

Lead root cause analysis beyond L2 depth (GPU failures, firmware issues, Linux-level faults, HW/SW interactions).

Detect recurring patterns across sites and convert findings into durable fixes.

Own technical workstreams during high-severity incidents.

Vendor & R&D Collaboration

Build evidence packs and drive escalations with ODM and R&D.

Push for firmware, component, and platform-level resolutions.

Track outcomes and ensure knowledge flows back to operations.

Firmware & Platform Readiness (BIOS/BMC)

Support validation and rollout of firmware updates (risk assessment, staging, rollback planning).

Help operationalize platform standards across datacenters.

Knowledge & Enablement

Create scalable runbooks, troubleshooting guides, and error catalogs.

Turn investigations into playbooks that elevate L1/L2 teams.

Hands-on Support (As Needed)

Travel to datacenters for complex troubleshooting, new platform readiness, or incident containment.

We expect you to have: 

Strong hands-on experience with datacenter servers and deep Linux troubleshooting.

Ability to diagnose across hardware, BIOS/BMC firmware, and Linux (logs, drivers, storage basics, performance triage).

Structured incident response experience and clear communication under pressure.

Experience driving evidence-based escalations with vendors/R&D.

Fluent English (written and spoken).

It will be an added bonus if you have: 

Strong familiarity with GPU server platforms and tooling (for example: nvidia-smi, dcgmi, Linux logs correlation).

Experience with ipmitool and Redfish workflows, firmware lifecycle, and staged rollouts.

Scripting skills (bash and basic Python) for log collection, triage automation, and simple reliability analysis.

Exposure to OCP-based platforms and ODM manufacturing ecosystems.

Experience supporting enterprise bare metal customers under contractual SLAs.

Benefits & Perks:

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
