Role summary
Our compute footprint is growing fast to support our science and engineering teams. We’re hiring a Field HW Engineer to understand end-to-end systems, execute complex/vendor-level interventions, and guide L1 engineers on site—without direct line management. You’ll work hands-on across compute, storage, interconnect and cooling to keep one of France’s largest GPU/CPU clusters healthy and scalable.
Location: Bruyères-le-Châtel — on-site, field role (multi-site mobility: Paris area and nearby)
Reporting line: Hardware Ops
Impact
• Compute is a key lever for Mistral’s success and our largest spend item.
• Direct impact on scale: you’ll restore service on complex incidents and raise the bar on reliability as we grow.
• Enable breakthrough AI: your work unlocks science & engineering teams to deliver state-of-the-art AI.
What you will do
• Lead complex interventions: plan and execute vendor-level or multi-node operations (e.g., full rack work, intricate recabling, post-restart diagnosis), own risk assessment/rollback, and coordinate with vendors (RMA/escalations).
• Advanced diagnostics: correlate symptoms across compute, storage, interconnect, cooling; read system indicators (LED/POST/beep), BMC/IPMI consoles, and logs to identify root causes.
• Guide and uplift L1s: coach on safe practices (ESD/LOTO), first-line triage, rack craftsmanship, documentation quality; pair on tricky procedures. (No people management.)
• Process & automation: improve SOPs/checklists; propose/build small automation (Python/Bash) for photo/serial capture, inventory sync, dashboards/alerts; shorten MTTR.
• Safety & compliance: enforce lockout/tagout, ESD, PPE; ensure audit-ready tickets, evidence and change traces.
• Parts & logistics (advanced): plan spares strategy, track failure trends, and drive proactive vendor actions.
About you
• 5+ years in data center/server h
