About Rivian

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 seeking a skilled and detail-oriented Sr. Soiling and Water Management Engineer to join our Environmental Performance team. The successful candidate will be responsible for vehicle-level target setting, simulation of soiling and water management scenarios, test standard development, vehicle-level testing support and eventually attribute performance sign-off. You will utilize advanced multiphase Computational Fluid Dynamics (CFD) methods to model complex particle and fluid flows (rain, mud, snow, dust) and validate these models through rigorous wind tunnel and proving grounds testing. Your work will directly influence exterior design, aerodynamic surfacing, and active cleaning systems, ensuring Rivian vehicles operate flawlessly in the harshest environments.

Responsibilities
Simulation & Analysis: Execute high-fidelity Soiling and Water Management simulations (CFD) to optimize vehicle performance in a wide variety of environments from deep water to soiling and cleaning of sensor suites.Attribute Target Setting: Conduct product research to highlight industry trends and identify opportunities for future product differentiation.
