Staff Mechanical Engineer @ Rivian
About
As a Staff Mechanical Engineer at Rivian, I focus on designing and developing exterior roof trims for automotive applications, leveraging my expertise in manufacturing engineering and product development. My role involves leading cross-functional teams to ensure the successful execution of production parts, fostering collaboration, and maintaining rigorous quality standards. With over four years of experience at Rivian, I have contributed to launching critical automotive components such as roof trims for the Amazon Delivery Van and the design of rear metal bumpers for off-road vehicles. My work on B-Pillar appliques for flush glazing systems demonstrates a strong commitment to innovation and precision engineering, aligning with Rivian's mission to redefine mobility through sustainable technologies.
