Résumé du poste

Mistral.ai is seeking a Field Hardware Engineer to sustain and scale our GPU/CPU clusters across Paris-area sites. You will work hands-on with compute, storage, interconnects, and cooling, guiding L1 engineers and coordinating with vendors on complex on-site interventions.

Based in Bruyères-le-Châtel, this on-site field role requires strong data-center hardware chops, safety discipline, and ability to travel between sites.

Qualifications

• 5+ years in data center/server hardware in production.
• End-to-end hardware expertise across CPU/memory/PCIe and accelerators.
• Diagnostics depth with BMC/IPMI and Linux logs.
• Safety discipline: ESD/LOTO/PPE; auditable work.
• Strong communication; able to mentor L1s.

Responsabilités

• Plan and execute vendor-level or multi-node operations; own risk assessment/rollback.
• Analyze system indicators and logs to identify root causes.
• Coach L1s during live operations; ensure safe practices.
• Improve SOPs; build small automation (Python/Bash) for ops.
• Plan spares strategy and track failure trends.

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.
• Parts & logistics (advanced): plan spares strategy, track failure trends, and drive proactive vendor actions.

About you

• 5+ years in data center/server hardware or L2/L3 hardware support, with proven complex hands-on work in production (HPC/AI/Cloud at scale).
• End-to-end hardware expertise: comfortable across CPU/memory/PCIe cards (incl. accelerators), NICs, PSUs, drives, network, power and cooling (including DLC); strong judgment on when/how to elevate.
• Diagnostics depth: confident in analyzing BMC/IPMI logs, linux software logs and crashes simple CLI checks; methodical root cause analysis.
• Safety & discipline: impeccable ESD/LOTO/PPE habits; zero rough handling; clean, labeled, auditable work.
• Communication & mentoring: crisp status/handovers; able to coach L1s during live operations. Provide technical documentations to L1s or other team
• Mobility: willing to travel between sites (Paris area or nearby regions, occasionally in Europe or US)).

Nice to have

• Vendor tools (iDRAC/iLO/IPMI), RAID/storage basics (NVMe/SAS/SATA), high-speed interconnect (Ethernet/InfiniBand).
• Coding/automation (Python/Bash) for small ops tools and reporting.
• Experience with ticketing (Jira/ServiceNow), inventory/RMA flows, vendor coordination.
