Senior Thermal Analyst

Introduction: The Johns Hopkins University Applied Physics Laboratory (APL), a national leader in scientific research and development, located midway between Baltimore and Washington, DC is seeking a Senior Thermal Analyst.

Job Summary: Provide thermal engineering support and for space system applications with focus on space instrument thermal design. Perform end-to-end thermal design, analysis and testing of space hardware; specify and procure thermal control hardware; specify and assist in the design multi-layer-insulation; and thermal oversight of subcontracted systems. Define thermal requirements and generate thermal and thermal vacuum test plans and specifications for flight and engineering hardware. KEYWORDS: Thermal analysis, thermal vacuum, temperature cycling.


  1. Lead engineer for the thermal design and analysis of space systems, instruments and components. Develop thermal models and conduct analyses to predict system thermal performance during flight conditions. Direct and work with subsystem lead engineers and thermal technician in the design and development of spacecraft and instrument space flight thermal control systems.

  2. Responsible for all aspects of thermal vacuum testing. Develop thermal models and conduct analyses in support of thermal system testing. Design and development of system and subsystem thermal test configurations. Generate test plans and specifications, participate in execution of test and perform analysis of test data. Correlate thermal analysis models based on system and subsystem test data.

  3. Provide program support at status meetings and reviews - formal & informal presentations and documentation.

  4. Participate in and/or initiate independent proposal and technology development efforts in advanced thermal system development. Provide thermal engineering support of department proposal efforts as required.

  5. Provide thermal design support for other space system applications.
