Senior Thermal Analysis Engineer, Space Suit Systems

Axiom Space; Georgia; On-site; USD 110,000 - 160,000; Full time

Job summary

Axiom Space in Georgia is seeking a Senior Thermal Analysis Engineer III to own the thermal design of AxEMU components, build and validate models, and support testing to certify human-rated hardware for NASA and commercial partners.

The role requires strong modeling skills (Thermal Desktop, SINDA/FLUINT, ANSYS), experience with conduction, radiation, and convection, and the ability to communicate results to mixed technical audiences.

Qualifications

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field, plus 4+ years of relevant thermal engineering experience
• Thermal analysis experience on human-rated or crewed hardware
• Proficiency with thermal modeling tools (Thermal Desktop, SINDA/FLUINT, Ansys, or equivalent)
• Strong foundation in conduction, radiation, and convective heat transfer, and comfort with hand and spreadsheet calculations
• Experience with thermal testing and thermal math model validation
• Working knowledge of CAD software (SolidWorks, SpaceClaim, or similar)
• Excellent written and verbal communication, including technical reports and presentations to technical and non-technical audiences
• Strong time management and ability to deliver high-quality work under tight deadlines

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
• Demonstrate compliance with program requirements, human-rated design standards, and mission objectives through thermal analysis
• Support thermal vacuum and human-in-the-loop testing: test planning, instrumentation recommendations, execution support, and model-to-test correlation
