About the role
You will be the owner’s technical authority for the mechanical, electrical, and controls systems behind Crux’s TPU fleet. You will translate Google’s TPU cluster requirements — densities, liquid cooling, power quality, network topology constraints — into facility requirements, and hold every design to them: our own basis of design on greenfield projects, and third-party provided designs.
What they're looking for
- 10+ years in mechanical/electrical engineering for data centers or critical facilities — design, commissioning, or owner’s engineering — with deep working knowledge of NEC, NFPA, IEEE, and ASHRAE standards and BMS/EPMS systems
- Direct experience with high-density AI/HPC infrastructure: direct-to-chip liquid cooling, 100kW+ racks, large-scale UPS/generator plants — you have designed, commissioned, or operated it, not just read about it
- Owner-side design review experience — holding AE engineers, vendors, and developers accountable to a requirements set and putting a cost on every deviation
- PE license (mechanical or electrical)
- TPU or large GPU cluster deployment experience, or close work with hyperscaler hardware/facility integration teams
- Commissioning credentials or agent-side experience (Levels 1–5, IST) on mission-critical projects
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 brings together power, high-density data centers, TPU silicon, networking, orchestration software, and ongoing operations as one integrated system.
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.
