Field Hardware Engineer, HPC
About this role
About Mistral Mistral provides full-stack AI solutions: from frontier models to developer tools, applications, and compute. We partner with enterprises tackling the hardest problems—across high-stakes industries like finance, manufacturing, defense, healthcare, and the public sector—co-creating customized AI systems that they can run on their terms. We are a dynamic, collaborative team passionate about AI and its potential to transform society.
Our diverse workforce thrives in competitive environments and is committed to driving innovation. Our teams are distributed between Europe, North America, Asia and the Middle East. We are creative, low-ego and team-spirited. 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.
