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.

Role Summary

We are looking for a motivated Junior Fluid Dynamics Engineer to join our team and contribute to the aerodynamic development of our next-generation electric adventure vehicles. In this role, you will provide critical technical support to the aerodynamics team, moving from early-stage simulations to real-world production validation.
As an entry-level engineer, you will work under the guidance of Senior and Staff engineers to balance the demands of drag reduction, lift balance, and cooling requirements with the aesthetic vision of our Design Studio. This is a hands-on role where you will transform raw fluid-dynamics data into actionable insights that help define the efficiency and capabilities of our fleet.
