Senior Thermal Engineer, Expeditionary AI / HPC Data Centers

The role

You will own the thermal management of expeditionary AI/HPC data centers. This involves designing and analyzing cooling systems for modular compute and command-and-control infrastructure used in austere environments.

What you will do

• Own the thermal design and analysis of deployable data center cooling systems.
• Use first principles to run hand calcs, spreadsheets, and MATLAB/Python first-order models.
• Define cooling architecture and heat-rejection strategy.
• Develop cooling approaches for high-density racks.
• Work with electrical, mechanical, and facilities engineers to characterize heat loads.
• Weigh cooling architectures against reliability, efficiency, and total cost.
• Own the thermal FEA/CFD and system models.
• Lead prototype builds, field testing, commissioning, and operational validation.
• Present thermal status at internal and customer reviews.
• Develop internal tools to improve analysis effectiveness and efficiency.

Required qualifications

• MS or higher in mechanical engineering, applied physics, or related field focused on heat transfer, fluid dynamics, and HVAC
• In-depth understanding of heat transfer and fluid dynamics
• 5+ years designing thermal management systems for data centers or comparable mission-critical infrastructure
• Full-spectrum data center thermal experience—air-side and water-side cooling, heat rejection, chilled water plant design, power density management, and liquid cooling
• Steady-state and transient system modeling of thermal management systems, including HVAC and refrigerant simulations
• Validating and testing data center thermal equipment, with knowledge of applicable operating standards
• Track record of staying abreast of the latest data center thermal management technologies
• CAD experience with Siemens NX or SolidWorks

Nice to have

• Coding in Python or MATLAB for applications such as lumped-capacitance steady-state and transient analysis
• Thermal FEA/CFD experience—STAR-CCM+, ANSYS, Icepak or FloEFD
• Familiarity with efficiency metrics (PUE/WUE) and thermal design for high-density AI/HPC compute
• Experience with modular, transportable, or ruggedized data centers and operation in austere, high-ambient environments
• Be able to obtain and hold a U.S. Secret security clearance

Benefits

• Comprehensive, competitive benefits package available at little to no cost to employees

Before you apply

• Be able to obtain and hold a U.S. Secret security clearance
• Consent to Anduril Industries using a third-party service provider to conduct pre-employment risk, integrity, and due diligence screening
