Thermal Engineer

We are looking for a Principal Thermal Engineer to own the thermal architecture, design, analysis, testing, and flight execution of thermal control systems. This is a deeply hands-on leadership role combining significant individual technical contribution with building and leading the thermal engineering team.

Responsibilities

• Own the thermal architecture across the spacecraft, including active and passive thermal control systems.
• Design active thermal systems including cold plates, coolant loops, pumps, heat exchangers, thermal interfaces, insulation, heaters, and deployable radiators .
• Lead key engineering trades across performance, mass, cost, reliability, manufacturability, schedule, and operations .
• Build and correlate thermal models for spacecraft, payloads, and subsystems against ground-test and flight data .
• Take thermal hardware from concept through manufacturing, integration, testing, qualification, and flight .
• Build and lead the thermal engineering team, including hiring, mentoring, technical reviews, and verification standards.

Skills & Experience

• 8+ years of hands-on thermal engineering experience spanning design, analysis, hardware development, and testing.
• Strong experience with thermal analysis and modeling tools such as Thermal Desktop, ANSYS, or equivalent .
• Experience with active thermal control in demanding environments such as space, aerospace, automotive, data centers, power, industrial, or petroleum.
• Strong understanding of pumped fluid loops, liquid cooling, cold plates, heat exchangers, radiators, or other high-power thermal systems .
• Experience taking complex hardware from architecture and design through qualification and production or flight .
• Comfortable leading engineers while remaining deeply hands-on technically.
• Experience with high-power thermal systems, data center cooling, power-plant systems, automotive thermal systems, refrigeration, or petroleum process systems.
