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
We operate development centers in Plymouth, MI, Irvine CA and
San Jose, CA, and Surrey, England, as well as a manufacturing
facility in Normal, Illinois.
