Founded in 2017,</strong><strong>&nbsp;we’re delivering low-cost and large-scale energy storage and producing battery materials in the U.S. for the first time, all from batteries we already have.</strong></p> </div> </div> </div> </div> </div></div><p class="s3"><span style="font-size: 12pt;"><strong><span class="s2">Mechanical Engineer - Battery Sorting, Energy Storage</span></strong></span></p> <p class="s3"><span class="s4" style="font-size: 12pt;">Do you want to design and build the automated systems that make battery recycling possible at scale? Join the Battery Sorting team at Redwood Materials, where we are building a world-class, state-of-the-art, ML-enabled sorting platform that integrates conveyors, diverter mechanisms, computer vision, and operator-assist systems to classify and route thousands of end-of-life batteries per hour across diverse chemistries and form factors.</span></p> <p class="s3"><span class="s4" style="font-size: 12pt;">Our team partners closely with Controls, Software, and Production Engineering to solve tightly coupled electromechanical and AI-driven challenges as we scale the infrastructure driving the circular battery economy. By increasing the reach of recycled and sustainable materials, we are transforming the global battery supply chain.</span></p> <p class="s3"><span class="s4" style="font-size: 12pt;">As a Mechanical Engineer on the Sorting team, you'll work alongside a world-class, cross-functional group of engineers to design, fabricate, integrate, and sustain production sorting equipment. We're looking for hands-on problem solvers who are energized by rapid iteration, people who can move fluidly between CAD, the shop floor, and the production line to keep hardware performing.</span></p> <p class="s3"><span class="s4" style="font-size: 12pt;">If you're ready to make a tangible impact on the future of sustainable manufacturing, we want to hear from you.</span></p> <p class="s3"><span style="font-size: 12pt;"><strong><span class="s5">Responsibilities:</span></strong></span></p> <div class="s7"> <ul> <li style="font-size: 12pt;"><span class="s4" style="font-size: 12pt;">Design, prototype, and implement mechanical assemblies for sorting line subsystems including infeed, outfeed, conveyors, diverters, and guarding</span></li> <li style="font-size: 12pt;"><span class="s4" style="font-size: 12pt;">Collaborate with production engineering to troubleshoot and improve existing sorting equipment and processes to maximize throughput and uptime</span></li> <li style="font-size: 12pt;"><span class="s4" style="font-size: 12pt;">Apply engineering fundamentals (structural sizing, mechanism design, tolerance analysis) to deliver robust hardware solutions</span></li> <li style="font-size: 12pt;"><span class="s4" style="font-size: 12pt;">Create detailed models and engineering drawings in SolidWorks for custom fixtures, brackets, enclosures, and conveyor components</span></li> <li style="font-size: 12pt;"><span class="s4" style="font-size: 12pt;">Support machine activation alongside the controls engineering team;
