Axiom Space fosters a work environment inclusive of all perspectives. We are the pioneers of commercial space, leading the transformation of low-Earth orbit into a global space marketplace. Our mission-driven team is seeking a bold and dynamic Senior Thermal Analysis Engineer (Level III) who is fueled by high accountability, execution horsepower, and driven to understand our world, science/technology, and life itself, for the benefit of all on Earth and beyond.

POSITION SUMMARY

Given the complexity and fast-paced nature of the Axiom Space environment, we are seeking a resilient, highly motivated, and energetic Senior Thermal Analysis Engineer (Level III) to assist in building AxEMU, a next-generation spacesuit for NASA and commercial partners.

As a Senior Thermal Analysis Engineer III, you will own the thermal design and analysis of key suit components, including the Portable Life Support System (PLSS), the Pressure Garment System (PGS), and related EVA hardware. You’ll build and run models, support testing, and present results that drive design decisions and help certify the suit for human spaceflight.

You’ll work with limited supervision on well-defined problems and elevate the more ambiguous, cross-cutting issues to senior technical staff. If you thrive in a fast-moving environment and want your analysis to fly with a crew, this role is for you.

KEY DUTIES & RESPONSIBILITIES

• Own the thermal design and documentation for assigned AxEMU components, contributing to the overall suit thermal design

• Develop, validate, and maintain detailed thermal models (Thermal Desktop, SINDA/FLUINT, or equivalent) of the PGS, PLSS, and other assemblies across mission phases and operating conditions

• Run system-level thermal models and integrate subsystem results into suit-level analyses

• Perform CFD analysis of assigned thermal-fluid problems and deliver clear, usable results to the design team
