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><h3><span style="font-size: 12pt;"><strong>The Redwood Vision: Modernizing the Grid</strong></span></h3> <p><span style="font-size: 12pt;">Imagine being at the epicenter of the next great industrial shift. Just as the electric vehicle revolution redefined the car as a software-defined machine, Redwood Materials is redefining the global energy grid. We aren’t just managing batteries; we are building the "nervous system" for a circular energy economy.</span></p> <p><span style="font-size: 12pt;">Our San Francisco R&amp;D team is architecting the transition from static, hardware-heavy infrastructure to dynamic, software-controlled ecosystems. We are proving that a sustainable, 100% renewable grid isn't just a goal—it’s a technical reality powered by superior control intelligence. We are looking for the "architects of the electron" to help us make fossil-fuel peaker plants a thing of the past.</span></p> <p><span style="font-size: 12pt; font-family: helvetica, arial, sans-serif;"><strong>Power Electronics Controls Engineer</strong></span></p> <p><span style="font-size: 12pt;">As a Power Electronics Controls Engineer, you will lead the design and implementation of the intelligent "brains" for our next-generation Battery Energy Storage Systems (BESS) and mixed-asset energy sites. You will be responsible for the entire journey of our control systems—from white-space conceptualization and advanced modeling to real-world grid impact. Your work will ensure that recycled and new battery assets work in perfect harmony to stabilize the grid and optimize high-power conversion at an industrial scale.</span></p> <p><span style="font-size: 12pt; font-family: helvetica, arial, sans-serif;"><strong><span data-ccp-props="{}">Responsibilities will Include:</span></strong></span></p> <ul> <li style="font-size: 12pt;"><span style="font-size: 12pt;">Software-Defined Power: Design and optimize advanced control algorithms for high-power BESS, focusing on grid-forming, grid-following, and complex multi-asset energy site synchronization</span></li> <li style="font-size: 12pt;"><span style="font-size: 12pt;">High-Power Conversion Architecture: Develop bidirectional DC/DC and AC/DC control schemes for industrial-scale storage, ensuring peak efficiency, thermal stability, and safety across all operating modes</span></li> <li style="font-size: 12pt;"><span style="font-size: 12pt;">Digital Twin Development: Build high-fidelity "Digital Twins" of power stages and grid environments using PLECS and MATLAB/Simulink to predict system behavior under extreme transient and fault conditions</span></li> <li style="font-size: 12pt;"><span style="font-size: 12pt;">Virtual &amp; Hardware Validation: Architect and lead comprehensive Hardware-in-the-Loop (HIL) testing environments (Opal-RT/Typhoon) to rigorously stress-test control firmware before deployment</span></li> <li style="font-size: 12pt;"><span style="font-size: 12pt;">Circular Asset Integration: Collaborate with battery and systems teams to implement control strategies that optimize the performance and longevity of mixed-asset arrays, including the integration of recycled battery chemistries</span></li> <li style="font-size: 12pt;"><span style="font-size: 12pt;">Cross-Functional Leadership: Partner closely with electrical, firmware, and thermal engineers to define the long-term roadmap for modern, resilient energy storage site controllers</span></li> </ul> <p><span style="font-size: 12pt;"><strong>Desired Qualifications:</strong></span></p> <ul> <li style="font-size: 12pt;"><span style="font-size: 12pt;">Educational Depth: MSc or PhD in Electrical Engineering with a specialization in Power Electronics Control Systems.
