Senior Thermal Engineer - Electronics Cooling (TS Clearance)

Energy Jobline ZR; Costa Mesa (CA); On-site; USD 146,000 - 194,000; Full time

Job summary

Anduril Industries in Costa Mesa, CA, seeks a Senior Thermal Engineer to own the thermal design of electronic assemblies across air vehicles, maritime, ground systems, and wearables. You will apply heat transfer and CFD principles, perform thermal analyses, and verify designs through prototype builds and tests.

Strong collaboration with cross-functional teams is essential, along with clearance eligibility and a passion for defense.

Qualifications

• MS or higher degree in mechanical engineering, aerospace engineering, applied physics, or a related field with a focus on heat transfer and fluid dynamics.
• In-depth understanding of heat transfer and fluid dynamics.
• 5+ years of experience designing thermal solutions for electronics or integrated hardware products.
• Electronics cooling and packaging—TIMs, heat sinks, heat pipes, cold plates, and enclosure heat rejection.
• Experience designing both passive and active thermal management systems.
• Thermal testing experience—sensor selection, data acquisition, and data post-processing.
• Thermal FEA/CFD experience—STAR-CCM+, ANSYS, Icepak, or FloEFD.
• CAD experience with Siemens NX or SolidWorks.
• Be able to obtain and hold a U.S. Top Secret security clearance.
• Passion for defending the United States and her allies.

Responsibilities

• Own the thermal design and analysis of electronics—from board-level to enclosures—for multi-platform products.
• Use first principles and hand calculations, spreadsheets, and MATLAB/Python models to inform design decisions.
• Define thermal architecture and heat-rejection paths to keep components within limits.
• Establish operating conditions accounting for altitude, humidity, solar load, and human-contact limits.
• Collaborate with electrical, mechanical, and systems engineers to document power dissipation.
• Present thermal status at reviews and communicate timelines and status.
• Develop internal tools to improve analysis efficiency and support failure/root-cause analysis.
