The engineer will:

• Develop and execute detailed thermal models for spaceflight hardware and instruments
• Perform transient and steady‑state thermal analyses using tools such as Thermal Desktop, Sinda/Fluint, ANSYS, or equivalent
• Define thermal requirements at subsystem and system levels
• Conduct thermal verification planning, including test planning, correlation, and model updates
• Review design artifacts to ensure compliance with thermal and system requirements
• Interface with mechanical, structural, fluids, and systems engineering teams to develop integrated solutions
• Prepare formal thermal analysis packages documenting predicted results for project/program management at milestone reviews, including analysis reports, verification matrices, and presentation material
• Participate in technical interchange meetings, design reviews, hazard analysis discussions, and project planning sessions
• Support troubleshooting of hardware non‑conformances related to thermal behavior
• Collaborate with outside vendors and personnel from other NASA centers in the development of integrated flight systems

• Capture and interpret system‑level thermal and environmental inputs
• Develop, verify, and validate transient thermal models in Thermal Desktop and Sinda/Fluint
• Conduct system‑level trade studies to assess design options and thermal control strategies
• Generate detailed temperature and heat‑transfer predictions to support mission requirements
• Document analysis results and communicate findings to engineering and program teams

• BS degree (MS or PhD preferred) from an ABET‑accredited institution in Mechanical, Chemical, or Aerospace Engineering; or a related field with an emphasis in heat transfer or thermal analysis
• Experience conducting assessments and verification of spaceflight equipment
