They just need to come back. Today Redwood is the largest lithium-ion battery recycler in North America — recovering, refining, and redeploying critical minerals from end-of-life batteries back into the supply chain. On the energy side, Redwood has deployed the largest second-life battery project in the world, delivering power to AI data centers in months rather than years using proprietary energy architecture engineered entirely in-house. The company is profitable, the market it operates in is projected to grow 20 to 50 times over the next decade, and Redwood is the only company with the supply chain, the technology, and the operational scale to lead it.</strong></span></p> </div> </div> </div> </div> </div></div><p><strong><span data-contrast="none">System Modeling Engineer, Redwood Energy</span></strong><span data-ccp-props="{}"> </span></p> <p><span data-contrast="none">You will be an early member of a new engineering team, taking a hands-on role in the design, development, and integration of a new product. This position focuses on developing Multiphysics modeling platform to drive the system design of a novel energy storage system. These models must be robust enough to support multiple users, but agile enough to quickly drive a diverse array of design decisions.</span><span data-ccp-props="{}"> </span></p> <p><span data-contrast="none">The ideal candidate is highly self-driven, adaptable to a startup environment, and eager to take on novel technical challenges.
