• Duties described below are at the full-performance level. Duties assigned at a lower grade level will be of more limited scope, performed with less independence and limited complexity; duties will be commensurate with the grade of selected employee.
• Serve as test and development engineer responsible for conducting tests to evaluate dynamic power conversion technologies against mission requirements such as thermal cycling, extended operation, launch vibration, and centrifuge testing.
• Design, fabricate or procure experimental hardware and plan tests to quantify performance or evaluate reliability under relevant conditions. Evaluate resulting data, compare data with analytical predictions, and resolve differences.
• Work collaboratively with team to plan and conduct tests to advance dynamic power conversion technology such as Stirling engines, alternators, and heating, cooling, instrumentation, and data systems.
• Develop engineering drawings, analytical models, and technical reports related to thermal energy conversion systems and/or test apparatus used for evaluation of such devices.
• Use commercial engineering software and custom computer codes to design mechanical and thermal components, evaluate interfaces and generate performance predictions. Resolve technical issues using sound engineering principles and analysis.
