Senior Critical Infra Lead - AI Compute Resilience

Mistral Ai; Paris; On-site; EUR 80,000 - 120,000; Full time

Job summary

Mistral AI is seeking a senior facilities engineer to provide technical assurance for critical electrical, mechanical and life-safety infrastructure at assigned colocation sites. You will monitor resilience, review maintenance plans, and guide incident response to protect AI compute availability.

In this hands-on role, you will own risk registers, assess utilities, validate documentation, and coordinate with colocation providers, IT Operations, and OEM partners.

Qualifications

• 5–7+ years in critical facilities engineering, commissioning, data center operations or technical assurance in high-availability environments.
• Strong practical knowledge of critical electrical infrastructure (UPS, generators, MV/LV distribution, switchgear and protection) and mechanical systems (cooling plant, pumps, controls and heat rejection).
• Ability to review single-line diagrams, operating sequences, technical procedures, maintenance plans, commissioning evidence and root-cause analyses.
• Demonstrated experience troubleshooting complex infrastructure incidents and influencing external technical teams without direct line authority.
• Clear written and verbal English communication, sound judgment under pressure and willingness to travel and participate in incident escalation as needed.

Responsibilities

• Own and maintain the site technical risk register, including electrical and mechanical single points of failure, maintenance exposure, redundancy limitations, cooling capacity, liquid-cooling interfaces and common-mode failure scenarios.
• Assess the resilience of utility connections, MV/LV distribution, transformers, generators, UPS, switchgear, busways, protection systems, pumps, cooling plant, controls and monitoring against the contracted operating envelope.
• Review provider preventive maintenance strategies, schedules, critical asset condition and outstanding defects; identify maintenance deferrals and vulnerabilities that may affect AI compute availability.
• Critically review high-risk methods of procedure, electrical switching and isolation plans, planned impairments, work sequencing, contingency measures, rollback plans and restoration criteria.
• Validate the completeness and quality of technical documentation, including single-line diagrams, P&IDs, operating sequences, alarm matrices, capacity records, asset registers and operating procedures.
• Use BMS/EPMS trends, alarms, power-quality records and cooling telemetry to identify abnormal operating conditions, capacity constraints and deteriorating resilience before service is affected.
