Founded in 2017,</strong><strong> 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> </p> <p><span style="font-family: helvetica, arial, sans-serif; font-size: 12pt;"><strong><span data-contrast="auto">The Redwood Vision: Architecting the Future of the Grid</span></strong><span data-ccp-props="{}"> </span></span></p> <p><span style="font-family: helvetica, arial, sans-serif; font-size: 12pt;"><span data-contrast="auto">We are at the precipice of a global energy transition. At Redwood Materials, we are moving beyond battery recycling to build the most advanced, circular energy ecosystem on the planet. Our goal is to shift the industry from static, hardware-heavy infrastructure toward agile, software-defined energy assets. The Software Validation team ensures that these complex systems are safe, resilient, and ready for grid-scale deployment.</span><span data-ccp-props="{}"> </span></span></p> <p><span style="font-family: helvetica, arial, sans-serif; font-size: 12pt;"><span data-contrast="auto">As a </span><span data-contrast="auto">Software Validation Engineer</span><span data-contrast="auto">, you are the bridge between pure code and physical reality.
