Test Engineer II, Thermal Control Systems

Vast is looking for a Test Engineer II, Thermal Control Systems, reporting to the Manager, Thermal Test Engineering, to support the development of systems required for the design and build of artificial-gravity human-rated space stations. 

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

At the heart of our artificial-gravity commercial space station program, the Thermal Test Engineering team takes full ownership of testing the hardware that keeps our Thermal Control Systems performing flawlessly. In this pivotal role, you’ll work cross-functionally to drive high-impact projects that are vital to the success of major test campaigns. 

You’ll design and execute  rigorous tests for components essential to the safety of future astronauts and passengers — and to the overall success of our mission. Your work will directly safeguard lives and enable humanity’s next giant leap in sustainable space habitation.

Responsibilities: 

• Own and drive the full lifecycle of assigned test campaigns for thermal systems and mission-critical components, leading strategic test initiatives that shape both near-term and long-term space habitat missions
• Lead cross-functional test initiative and scoped projects from concept to execution, delivering everything from targeted case studies and analytical assessments to the design, build, and instrumentation of complex, high-fidelity test environments
• Tackle the hardest technical challenges, performing deep root-cause investigations and coordinating with technicians, engineers, and leadership to implement robust, long-lasting corrective actions
• Establish and enforce rigorous test traceability, documenting every phase of design, planning, execution, and post-processed data to ensure alignment with subsystem performance and program level requirements

Minimum Qualifications:

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or a related engineering discipline
• Strong foundation in fluid systems — including fluid mechanics and design, relevant test standards and best practices, piping and instrumentation diagrams (P&IDs), test instrumentation and fittings, safety protocols, and troubleshooting methodologies
• Demonstrated experience owning and executing complex test campaigns, from defining objectives and Conop development through GSE design, build, instrumentation and on to operator training, test execution and data analysis
• Proven ability to lead cross-functional engineering projects, coordinating diverse stakeholders spearheading consensus building and project managing initiatives to successful, on-time completion
• A proactive, hands-on problem solver who thrives in dynamic, fast-paced environments and is comfortable operating autonomously to remove obstacles and deliver results
• Exceptional communication skills, with the ability to translate complex technical information into clear, actionable insights for both engineering and non-technical audiences while also reconciling differing perspectives in a professional and pragmatic manner

Preferred Skills & Experience:

• 2+ years of proven success in rapidly designing, developing, and delivering highly reliable products<
