About the Team

Battery Cells are the common denominator for every Tesla product. Our product requirements demand ground-up cell architectures with state-of-the-art performance, manufactured at volumes that are orders of magnitude higher than the products they power. Our environment is fast-paced and incredibly exciting. Tesla moves quickly, so being passionate and self-motivated to push your limits is critical. Our team works alongside engineering groups across various disciplines, requiring strong communication skills and a team-first mentality. You will work alongside seasoned industry experts, high aptitude recent graduates, and people from every stage in between.

We are seeking a highly motivated quality person to help continuously drive improvements to 4680 quality by gathering and utilizing data from downstream customers as well as the fleet of 4680 products. This person will track all opportunities to improve quality and drive those improvements to the product and process. They will also work with fleet analytics to build and maintain a model for product warranty and relative failure modes. This person is seasoned in manufacturing quality or reliability engineering for high reliability applications such as Li-ion cells, medical or a similar field with several years’ experience.
