• Perform steady-state and transient thermal analyses to evaluate spacecraft and spaceflight hardware performance under a wide range of operating conditions
• Support the design of thermal hardware, including heaters, radiators, multilayer insulation (MLI), and thermal interface components
• Create thermal models and perform heat transfer analysis for spacecraft and spaceflight hardware, including electronic chassis/boxes, printed circuit boards (PCBs), and printed wiring boards (PWBs)
• Model PCB and PWB designs and performance using thermal analysis simulation programs such as Thermal Desktop and

SINDA/FLUINT

• analysis tools such as MathCAD to assess the robustness of electrical power circuitry from a thermal standpoint
• Generate clear and comprehensive thermal documentation, including analysis reports, test plans, and test procedures
• Support thermal testing activities, including thermal vacuum (TVAC) test planning, test execution, and post-test data review
• Coordinate closely with cross-functional teams, including mechanical, systems, and avionics engineering, to ensure thermal requirements are understood, met, and verified
• Provide regular status updates on analysis progress and results, and support internal and external program reviews with technical input and documentation
• Contribute to continuous improvement of thermal analysis methodologies, tools, and best practices within a specialized thermal engineering environment
• Support multiple programs concurrently as needed, adapting thermal analysis approaches to different spacecraft and aerospace applications.

Essential Skills

• BS or MS degree in Mechanical Engineering, Aerospace Engineering, or a closely related field
• Ideally 10+ years of experience in mechanical engineering design and thermal analysis or related thermal modeling for aerospace or similar high-reliability systems
• Strong proficiency in thermal analysis modeling using standard software tools such as SINDA/FLUINT and Thermal Desktop
• Demonstrated experience performing steady-state and transient thermal analyses for spacecraft, NASA, or related aerospace systems
• Hands-on experience with thermal design for spacecraft or spaceflight hardware, including heaters, radiators, multilayer insulation (MLI), and thermal interfaces
• Experience creating and analyzing thermal models for electronic chassis/boxes, printed circuit boards (PCBs), and printed wiring boards (PWBs)
• Understanding of thermal interface materials such as RTV, ChoTherm, and similar materials, as well as wedge locks, rails, and other PCB and PWB mounting approaches
• Ability to use thermal analysis simulation programs such as Thermal Desktop and

SINDA/FLUINT

to model PCB and PWB designs and overall thermal performance

• Proficiency with engineering analysis tools such as MathCAD to assess the robustness of electrical power circuitry from a thermal perspective
• Strong written communication skills to generate clear analysis reports, test plans, and procedures, and to document assumptions, methods, and results
• Ability to collaborate effectively with mechanical, systems, and avionics engineering teams to define and verify thermal requirements
• Experience supporting thermal testing, particularly thermal vacuum (TVAC) test planning, execution, and data review.

Additional Skills & Qualifications

• Experience with electrical or electronics thermal analysis, including detailed analysis of power electronics and high-density boards, is a plus
• Familiarity with additional thermal analysis programs such as TRASYS, TSS, THERMICA, RADCAD, NEVADA, and

IDEAS/TMG

is highly desirable

• Background working on spacecraft, NASA missions, or related aerospace systems is strongly preferred
• Experience working in organizations focused primarily on thermal analysis or thermal engineering is beneficial
• Ability to manage work across multiple programs and adapt to changing priorities in a dynamic project environment
• Strong problem-solving skills and the ability to propose practical thermal design solutions based on analysis results
• Comfort presenting technical findings in program reviews and communicating complex thermal concepts to multidisciplinary teams.

Work EnvironmentThis role is based onsite at NASA Goddard Space Flight Center, working within a highly specialized thermal engineering organization dedicated exclusively to thermal analysis and design. The environment is collaborative and engineering-focused, with close interaction among mechanical, systems, avionics, and test teams. You will work with industry-standard thermal analysis tools such as Thermal Desktop, SINDA/FLUINT, ICEPAK, and MathCAD, and you will support both analytical work and test activities, including thermal vacuum (TVAC) testing. The position offers exposure to multiple spacecraft and aerospace programs, providing a strong platform for professional development and long-term growth in the thermal analysis discipline.
