- Build, execute, and validate thermal analyses at the component, sub-system, and vehicle level, including supporting tool development and automation
- Guide design and development engineers in the successful application of thermal sciences to achieve system and component requirements
- Develop and execute tests to support thermal systems development and qualification, including test article integration, instrumentation setup, and data processing
- Support vehicle and engine thermal system development and stage testing, as well as flight operations
Job requirements
- Bachelor's degree in Engineering or related field
- Experience in industry via internships or university collaborations
- Strong fundamentals in heat transfer and thermal analysis
- Hands-on experience with writing test plans and performing testing, instrumentation, and data analysis at the component and system level
- Experience with an engineering scripting language like MATLAB or Python
