Senior Thermal Engineer, Expeditionary AI / HPC Data Centers

About the role

We are looking for a Senior Thermal Engineer in Costa Mesa, CA to own the thermal management of expeditionary AI/HPC data centers—air-transportable, modular compute and command-and-control infrastructure built to run at forward operating locations. You will apply a deep understanding of heat transfer, fluid dynamics, and HVAC to keep high-density compute running reliably in austere environments with extreme temperatures and limited power.

Responsibilities

• Own the thermal design and analysis of deployable data center cooling systems—air-side and water-side cooling, heat rejection, chilled water plant, and liquid cooling—from rack and chip level up through the full facility.
• Use first principles to discern the right level of analysis, running hand calcs, spreadsheets, and MATLAB/Python first-order models before detailed design.
