Anduril Industries
Thermal Design Engineer
About this role
Anduril Industries seeks a Thermal Design Engineer to support thermal architecture and analysis for advanced defense systems including drones, aircraft, and missiles. The role combines first-principles heat transfer analysis, FEA/CFD modeling, prototype testing, and cross-functional collaboration to ensure mission-critical hardware performs reliably in demanding environments.
What you'll do
- Perform thermal design and analysis for integrated defense hardware products using hand calculations, spreadsheets, MATLAB, and Python
- Build and maintain thermal FEA/CFD models to predict system performance and establish design limits
- Support prototype builds and thermal testing including sensor selection, data acquisition setup, and results documentation
- Define thermal architectures for rugged environments and demanding flight conditions in collaboration with electrical and mechanical teams
- Present thermal analysis results and design recommendations in internal reviews
- Develop internal tools and workflows to improve thermal decision-making speed and quality
What they're looking for
- Heat transfer and fluid dynamics (conduction, convection, radiation, transient behavior)
- Thermal FEA/CFD modeling (ANSYS, STAR-CCM+, Icepak, or Flotherm preferred)
- MATLAB and Python for engineering analysis
- CAD tools (SolidWorks or Siemens NX preferred)
- Thermal testing and data acquisition
- First-principles engineering judgment and hand calculations
- Technical communication to cross-functional teams
- U.S. security clearance eligibility
