Senior Thermal Engineer

5+ years of experience designing, analyzing, or validating thermal systems for integrated hardware products.

Strong first-principles understanding of heat transfer and fluid dynamics, including conduction, convection, radiation, fluid flow, and transient thermal behavior.

Experience supporting thermal design for aerospace, aircraft, rocket, missile, UAV, defense, or other high-performance hardware systems.

Experience using thermal analysis, modeling, simulation, and/or physical test data to drive design decisions for passive or active thermal management systems.

Experience with thermal analysis tools such as STAR-CCM+, ANSYS, Icepak, Flotherm, or comparable FEA / CFD platforms.

Experience using MATLAB, Python, spreadsheets, or similar tools for first-order thermal modeling, transient analysis, or engineering trade studies.

In this role, you will own thermal design and analysis for advanced defense hardware across drones, aircraft, missiles, and related flight systems.

This role is ideal for someone with deep heat transfer and fluid dynamics fundamentals, strong thermal analysis capability, and the practical judgment to choose the right level of analysis, from first-order hand calculations through detailed FEA / CFD, to guide fast design decisions.

Own thermal design and analysis for integrated hardware products, including drones, aircraft, missiles, or related defense systems.

Use first-principles engineering judgment to determine the right level of analysis for each design decision, including hand calculations, spreadsheets, MATLAB / Python models, FEA, and CFD.

Define thermal architectures that can withstand rugged environments, demanding flight envelopes, and operational edge cases, including hot, cold, transient, and mission-specific thermal conditions.

Partner with electrical, mechanical, aerospace, software, and systems engineers to document power dissipation, operating modes, thermal constraints, and design tradeoffs.

The Thermal Engineering team enables Anduril’s rapid hardware development cycle by ensuring advanced defense systems perform reliably in demanding real-world environments. The team works across high-power, tightly integrated products where thermal architecture, analysis, testing, and cross-functional design decisions directly affect product performance, reliability, and mission success.
