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.
At Redwood Materials, we are architecting the future of grid-scale energy storage by transforming diverse, second-life automotive batteries and new assets into a unified, software-defined Battery Energy Storage System (BESS). We are looking for a deeply technical, hands-on Battery Software & Controls Integration Engineer who lives at the intersection of electrochemistry, embedded BMS firmware, and high-voltage pack hardware.
In this role, you won't just write high-level communication wrappers—you will get your hands dirty in the lab bringing up heterogeneous OEM battery packs off-vehicle, reverse-engineering proprietary BMS architectures, and validating the underlying battery state estimation algorithms. You will evaluate the accuracy of native OEM BMS outputs (SoC, SoH, SoP, cell balancing, and thermal limits) against physical pack behavior, while deploying and integrating Redwood’s in-house battery control and estimation algorithms to extract safe, maximum performance from aged and mixed-chemistry assets. You will also serve as the technical anchor with external automotive OEMs, defining the low-level firmware hooks and safety handshakes required for stationary grid operation.
This position is based in our San Francisco office and operates on an onsite work model.
In accordance with California pay transparency laws, the salary range for this position is listed below. Actual compensation may vary based on a variety of factors, including experience, education, and skills.
California Pay Range: $152,000 — $287,000 USD
The position is full-time. Compensation will be commensurate with experience.
