Senior Thermal Mechanical Engineer ECLSS

Axiom Space is building for beyond, guided by the vision of a thriving home in space that benefits every human, everywhere. We foster a diverse 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 person who is fueled by problem-solving, continuously curious, and driven to understand our world, science/technology, and life itself, for the benefit of all on Earth and beyond.

The Senior Thermal Engineer is responsible for developing and analyzing thermal models of spacecraft components and systems using tools like SINDA/FLUINT and Thermal Desktop. This role involves designing thermal control solutions, selecting appropriate thermal materials, and assessing environmental impacts from space conditions. The engineer will validate models with test data, ensure compliance with NASA standards, and document technical findings. Collaboration with cross-functional teams and participation in design reviews are essential, along with providing regular project updates to stakeholders.

DUTIES & RESPONSIBILITIES

• Develop and run component and spacecraft thermal math models (using software like SINDA/FLUINT, Thermal Desktop) to predict spacecraft temperature distributions during different mission phases.
• Design active and passive thermal control elements as part of providing solutions to thermal problems.
• Select and specify thermal materials, including thermal interface materials. Evaluate the effects of external space environments (solar radiation, Earth albedo, planetary infrared, deep space cold) on the spacecraft and provide recommendations.
• Correlate test data with analytical models to improve accuracy.
• Write technical reports and document thermal analysis results.
• Ensure analysis compliance with NASA standards and requirements.
• Participate in internal and external design reviews and provide recommendations for thermal improvements.
