About the role
You will own critical facility operations for one Crux site or campus — the electrical, mechanical, fire/life-safety, and controls infrastructure that keeps high-density, liquid-cooled TPU clusters continuously available. You will lead the 24/7 site facility team — chief engineer, shift technicians, and O&M contractors — and run the maintenance, procedures, drills, and change control that produce uptime, whether the building is Crux-owned or operated by a colocation partner you hold to SLA.
What they're looking for
- Site bring-up or major expansion experience: commissioning participation, acceptance testing, and the construction-to-operations handoff on a mission-critical facility
- 7+ years in Tier III/IV or hyperscale data center environments (Meta, Google, AWS, Microsoft, or a major colo operator)
- Direct-to-chip liquid cooling plant operations experience (CDUs, water chemistry, loop commissioning and tuning)
- Trade certifications (Electrical, HVAC, Controls), stationary engineer license, or military/nuclear power background
- CMMS/EAM administration experience and comfort with energy and reliability analytics
- Experience managing a colocation operator to SLA from the tenant side
More about this role
Crux AI is a newly formed, U.S.-based integrated AI infrastructure company created to remove the physical and operational constraints on consequential AI ambitions.

Crux is being capitalized to plan every layer together, develop each one to demanding standards, and operate the whole system with efficiency and reliability. That gives hyperscalers, frontier AI labs, sovereign customers, enterprises, and AI-native companies greater freedom to pursue the AI they are here to create.
