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.

Are you a Multibody Dynamics Engineer with a passion for problem-solving and a drive to innovate? Join our Durability Loads team and play a pivotal role in engineering the next generation of adventurous and resilient vehicles. You'll be instrumental in generating comprehensive vehicle loads, utilizing advanced
suspension and full-vehicle simulation methods. Your expertise will directly impact the robustness of our designs by providing critical load data to stakeholder teams.
We're looking for a highly motivated individual with a can-do attitude, exceptional problem- solving abilities, and strong organizational and time management skills. If you're ready to collaborate with an industry-leading team dedicated to pushing the boundaries of vehicle durability, we want to hear from you.
