What you will do
- Diagnose & operate core server/cluster components - Investigate and handle compute/storage hardware issues and interconnect problems, perform safe interventions to replace, re-seat, or recable components and restore service.
- Safety & procedures - Apply lockout/tagout (LOTO) and ESD discipline; follow pre/post-work checklists; maintain tidy, safe work areas.
- First-line diagnostics - Triage using LEDs, POST, beep codes and basic tests; capture evidence; open/update/close tickets with clear notes.
- Preventive maintenance - Provide feedback and ideas to improve proactive activities, monitoring, and targeted follow-ups on recurring or specific anomalies; help turn ad-hoc checks into SOPs, alerts, and dashboards.
- Parts & logistics - Receive and track parts, keep labeled inventory accurate, manage simple RMAs, and coordinate with vendors.
What they are looking for
- Hands-on mindset in datacenters/server hardware: you can install/re-seat/swap GPU/PCIe cards, NICs, PSUs, drives, and work cleanly in racks (rails, cabling, labeling). We also welcome candidates with strong Linux fundamentals (boot/check, logs) and scripting (Python/Bash) who are eager to learn hard
- Disciplined and meticulous: follows checklists, ESD/LOTO; no rough handling; careful with all high-value server components.
- Practical electrical basics: power-off, PPE, short-circuit risk awareness.
- Comfortable in racks: cooling, network, storage, PDU, cable management; can lift/mount safely (within HSE limits).
- Clear communicator: short factual updates; reliable teammate; punctual and process-minded.
- Hardware-passionate, professionally grounded: strong curiosity and craft mindset.
Nice to have
- HPC/AI/Cloud at scale experience (production environments), large-fleet/server install & maintenance in datacenters.
- Basic networking (Ethernet/InfiniBand) and basic Linux (boot/check; no coding needed).
- Coding/automation skills (Python/Bash): small tools/scripts to improve checklists, photo/serial capture, inventory sync, or simple monitoring/reporting.
- Experience with inventory/RMA tools and vendor coordination.
- Exposure to HPC/research/industrial environments.
Benefits
- healthcare coverage
- parental leave
- retirement plans
- relocation support
- wellness programs

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.
THE MISSION
You will work every day on the racks that power one of France's largest AI clusters.
Mistral's compute footprint is our single largest investment and the foundation of our AI research and engineering. We're hiring Data Center Hardware Engineers to keep our GPU/CPU clusters healthy, safe and growing — hands-on, in the data center, at the intersection of high-performance computing and physical infrastructure.
You'll join a small, senior team working at a scale few engineers get to experience: GPU-dense racks (H100/H200-class and next-generation platforms), high-speed interconnects, liquid-cooled systems — with new sites under development in France and beyond.
Hardware here is not someone else's problem. As part of a small on-site team, you carry responsibility for it end to end.
Location: On-site at one of our data centers in the South of Paris.
WHAT YOU'LL DO
- Diagnose & repair server and cluster hardware: CPUs, memory, drives, NICs, GPUs, PSUs, and interconnect problems (switches, cables, transceivers; Ethernet/InfiniBand).
- Intervene safely — power-off/lockout, ESD discipline, pre/post-work checklists, tidy and safe work areas.
- Capture everything — photos, serials, test results; open, update and close tickets with notes the next engineer can act on.
- Manage parts — receive, label and track inventory; run RMAs and coordinate with vendors.
- Help us get better — feed recurring anomalies into monitoring, alerts and SOPs; contribute small scripts (Python/Bash) if you have those skills.
- Be a good teammate — clear status updates, honest handovers, and respect for the people depending on the cluster.
ABOUT YOU
- Hands-on comfort in data centers or server hardware — you can (or will quickly learn to) work cleanly in racks: rails, cabling, labeling, mounting.
- Disciplined and meticulous: checklists aren't bureaucracy to you, they're craftsmanship.
- Practical electrical basics: power-off procedures, PPE, short-circuit risk awareness.
- Basic Linux (boot checks, logs) — scripting is a plus, not a requirement.
- Physically able to work in racks (lift, mount, maneuver) in a data center environment.
- Comfortable in a 24/7 operation, including a rotating on-call with emergency response expectations.
- Driver's licence (B) for travel between our sites.
EVEN IF YOU DON'T MATCH EVERY CRITERION
Many of our best hardware engineers came from research labs, telecoms, IT services or the military. If you are rigorous, curious and genuinely motivated by hardware at scale, we would be glad to hear from you — we assess demonstrated scope rather than keyword matching.
NICE TO HAVE
- HPC/AI/cloud production experience at scale; large-fleet server install and maintenance.
- Networking fundamentals (Ethernet/InfiniBand) beyond basics.
- Vendor/RMA tooling, ticketing (Jira/ServiceNow), inventory systems.
- Python/Bash automation for checks, capture, inventory or reporting.
