Staff Thermal Engineer

At Vast, our mission is to contribute to a future where billions of people are living and thriving in space. We are building artificial gravity space stations, allowing long-term stays in space without the adverse effects of zero-gravity. Our initial crewed space habitat will be Haven-1, scheduled to be the world’s first commercial space station when it launches into low earth orbit in May 2026. Our team is all-in, committed to executing our mission safely and on time. If you want to work with the most talented people on Earth furthering space exploration for humanity, come join us.

Vast is looking for a Staff Thermal Engineer, reporting to the Senior Manager, Thermal Analysis, to support the development of the systems that will be required for the design and build of artificial-gravity human-rated space stations. 

In this position, you will work independently and within a team environment, collaborating on tasks performed across a spectrum of disciplines, which will require excellent writing and oral presentation skills. The position will require a complete understanding and wide application of technical principles, theories, and concepts in the field of thermal engineering and experience developing active thermal control systems.

This will be a full-time, exempt position located in our Long Beach location.

Responsibilities: 

• Develop thermal systems requirements 


• Perform thermal analysis to develop and optimize thermal control designs and provide solutions to a wide range of difficult problems


• Coordinate and partner with other engineering disciplines


• Document thermal analyses and designs


• Review and approve drawings for thermal design hardware content


• Report results of analyses and design specifics to internal management and external customers


• Work with test engineering to plan and execute subsystem level thermal tests, especially thermal vacuum chamber (TVAC) testing, as well as perform associated analyses


• Provide feedback regarding impacts of possible cost and/ or schedule changes


• Work autonomously and be a subject matter expert to help guide junior engineers and cross-functional team members

Minimum Requirements:

• Bachelor’s degree in Aerospace Engineering, Physics, or related Engineering discipline with a minimum of 10+ years of related professional work experience, or a Master's degree in a related engineering discipline and 5+ years of experience


• Knowledge and understanding of the application of technical principles, theories, and concepts for developing active thermal control systems


• Expert with thermal analysis tool:, Thermal Desktop


• Extensive experience with TVAC testing

Preferred Skills & Experience:

• Design, analysis and integration experience of spacecraft thermal systems


• Experience using other thermal analysis tools (FloCAD, AnsysNSYS Mechanical, SINDA/G, SINDA/FLUINT, TSS)


• Experience using fluid analysis tools like AnsysNSYS Fluent, FloEFD, StarCCM+


• Experience using aerospace standard design tools (NX, CATIA, CREO)


• Experience with space vehicle thermal design and/or integration


• Experience with active and passive thermal control systems and technologies (pumped fluid loops, heat pipes, etc.)i.e. conduction, radiation, and convection heat transfer methods)


• Spacecraft and/or Payload background with experience through the entire system lifecycle from concept, design, production, integration, test, launch, to operation support


• Experience working on thermal design and troubleshooting efforts


• Ability to develop novel concepts for active thermal control systems for space habitats


• Detail-oriented and have excellent verbal and written communications skills, leadership skills, and organization skills
