About The Position

Rivian is on a mission to keep the world adventurous forever. This goes for the emissions-free Electric Adventure Vehicles we build, and the curious, courageous souls we seek to attract.
As a company, we constantly challenge what’s possible, never simply accepting what has always been done. We reframe old problems, seek new solutions and operate comfortably in areas that are unknown. Our backgrounds are diverse, but our team shares a love of the outdoors and a desire to protect it for future generations.

The responsibility of this position is to develop physics-based computational methods for Rivian propulsion systems to support product development. This candidate will engage in developing new and enhancing existing methods with the overall goal of improving Rivian's propulsion system design quality and reducing cost, with an emphasis on motor design and electrical power conversion.
