## Description

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 Europe and the US.

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.

## Responsibilities

### 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.

## Requirements

- 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).

## Nice to 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
