<div>
<p><span style="font-family: helvetica, arial, sans-serif;"><strong>Redwood Materials was founded in 2017 by JB Straubel, co-founder and former CTO of Tesla, on a simple but radical idea: the critical minerals powering the energy transition already exist. 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>

<p><span data-contrast="auto">Redwood is localizing a global battery supply chain that seamlessly integrates recovery, reuse, and recycling — keeping critical minerals in circulation and driving the energy transition. 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. The Power Systems Engineer, Hardware in the Loop will develop and validate BESS and inverter models using RTDS/RSCAD and CHIL platforms for grid-connected and off-grid applications, perform dynamic and transient testing, and support control validation, system integration, and project-specific performance requirements. This is a 100% on-site role. The role works closely with the energy storage team to develop accurate system models and design recommendations grounded in industry codes and standards.</span><span data-ccp-props="{}"> </span></p>
