Battery Software & Controls Integration Engineer, Energy Storage
Redwood Materials · San Francisco, CA · Posted 5 days ago
Take aged, mixed-chemistry second-life EV packs from bench bring-up to a unified grid-scale storage system, and serve as the technical anchor to automotive OEMs.
About Redwood Materials
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.
