The MA&T team is seeking a mid-level career Thermal Engineer II to join our MA&T Center in El Segundo, CA.
As a Thermal Engineer II you will be responsible for detailed thermal analysis on products throughout their lifecycle from initial design trade studies and proposals through qualification testing to enduring production support. The analyses will cover a wide range of difficult problems, requiring solutions that are imaginative, thorough, practicable, and consistent with organization objectives. The analysis tasks will span the spectrum from classical hand analyses to detailed analyses requiring the use of finite element analysis software.
A Thermal Engineer of this salary grade is expected to have a level of technical competence with thermodynamic principles. The Thermal Engineer will be held accountable for completing his/her work within the agreed upon cost and schedule. Additionally, the selected candidate will be expected to present their work for peer reviews and to be a peer reviewer for other engineers’ work.
Finally, the engineer is expected to plan and support tests, perform data reduction and engage in thermal model correlation.
- Perform hand calculations to determine scope of higher detail analysis models
- Perform detailed thermal analyses to solve various program thermal challenges
- Generate test plans required to validate analyses and verify hardware compliance to customer requirements
- Analyze test data to validate and correlate models
- Work with experienced analysts on problems of moderate complexity to provide the answers needed under program cost and schedule constraints
- Review your work with peers to ensure technical accuracy
- Present results to internal, external, and government customers
- Generate detailed documentation of work and archive for reference
- Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 2 years of prior relevant experience or An Advanced Degree
- Experience in thermal analysis with any of the following tools:
FloTHERM, PATRAN, Thermal Desktop/SINDA or ANSYS or equivalent - Experience in mechanical principles to solve classical thermal analysis solutions both inside and outside of finite element tools and an ability to work independently and manage multiple priorities
- Ability to obtain a U.S. government issued…
