GM • Warren, MI

2d • Hybrid

About The Position

The Thermal CAE Engineer will be responsible for capturing information from a variety of sources inside and outside of GM Defense, building and running analytical models, interpreting results for customers, attending development team meetings, interacting with compartment integration teams, and helping to drive the design that meets internal and external requirements. The Thermal CAE Engineer will build, run, and interpret results from various thermal models ranging in complexity from a single component to complex full vehicle systems. The engineer will be an employee within a diverse group of engineers supporting the virtual analysis needs of GM Defense. The engineer will be interacting with the GM thermal analysis groups, performing airflow and thermal simulations of varying complexity. The engineer will drive the design of unique vehicles and systems intended for government applications using virtual analysis tools.
