Thermal Design Engineer

The role

You will support thermal design and analysis for advanced defense hardware including drones, aircraft, and missiles. You will use first-principles engineering, modeling, and testing to inform design decisions for integrated hardware products.

What you will do

• Support thermal design and analysis for integrated hardware products
• Apply first-principles engineering judgment using hand calculations, spreadsheets, and MATLAB/Python models
• Build and maintain thermal FEA/CFD models
• Support prototype builds and thermal tests
• Contribute to defining thermal architectures for rugged environments
• Partner with electrical, mechanical, aerospace, and systems engineers
• Present thermal analysis results and recommendations in internal design reviews
• Develop internal tools, workflows, or analysis methods

Required qualifications

• MS in Mechanical Engineering, Aerospace Engineering, Applied Physics, or a related field with a focus on heat transfer, fluid dynamics, thermal sciences, or thermal systems
• Strong first-principles understanding of heat transfer and fluid dynamics, including conduction, convection, radiation, fluid flow, and transient thermal behavior
• Coursework, research, or internship experience in thermal analysis, modeling, or testing
• Experience with MATLAB, Python, or similar tools for engineering analysis
• Ability to communicate technical concepts clearly to cross-functional teams
• Ability to obtain and maintain a U.S. Top Secret security clearance

Nice to have

• 1-3 years of industry experience in thermal engineering for aerospace, defense, or high-performance hardware systems
• Experience with thermal analysis tools such as STAR-CCM+, ANSYS, Icepak, Flotherm, or comparable FEA/CFD platforms
• Experience with CAD tools such as SolidWorks or Siemens NX
• Graduate research in thermal-fluid systems, electronics cooling, aerothermal analysis, or related areas
• Exposure to thermal testing, including instrumentation, data acquisition, and test-to-model correlation
• Strong motivation to support Anduril's mission of defending the United States and allied partners

Benefits

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

Before you apply

• Ability to obtain and maintain a U.S. Top Secret security clearance
• By submitting your application, you consent to Anduril Industries using a third-party service provider to conduct pre-employment risk, integrity, and due diligence screening
