Thermal Analysis Engineer IV

Axiom Space is a human space exploration company, building era-defining space infrastructure and delivering technology-driven solutions that will empower civilization to transcend Earth. Beginning with Axiom Station, successor to the International Space Station, the company is pioneering a next-generation orbital settlement that will foster groundbreaking innovation and research in microgravity and drive the global space economy of tomorrow. Today, guided by the vision of leading humanity's expansion off planet, Axiom Space is the principal provider of commercial human spaceflight services and developer of advanced spacesuits for the Moon and beyond.

About the role

Given the complexity and fast-paced nature of the Axiom Space environment, we are seeking a resilient, highly motivated, and energetic Thermal Analysis Engineer IV to lead the design, development, verification, and certification of advanced spacesuit systems, including the Portable Life Support System (PLSS), Pressure Garment System (PGS), and associated extravehicular activity (EVA) hardware. This role is responsible for defining system-level thermal control strategies, integrating vendor and cross-functional engineering inputs into comprehensive thermal models, and leading thermal test correlation and validation efforts. The successful candidate will ensure compliance with NASA requirements and industry standards, provide technical leadership and mentorship to the thermal analysis team, and serve as the thermal discipline subject matter expert during program reviews, milestone events, and direct customer technical engagements.

Responsibilities

• Develop, validate, and maintain detailed thermal models (Thermal Desktop, SINDA/FLUINT, or equivalent) of spacesuit assemblies and subsystems — including the Pressure Garment System, TMG, and LCVG — across all mission phases
• Perform thermal analyses to ensure compliance with program requirements, human-rated design standards, and mission objectives
• Analyze LCVG performance and its interaction with garment insulation layers to support crew thermal comfort and metabolic heat rejection requirements
• Support thermal vacuum and human-in-the-loop testing, including test planning, instrumentation placement guidance, and model-to-test correlation
• Support verification and validation activities, including anomaly investigation and closure
• Author and review technical reports, analysis packages, and
