Redwood Materials is building the U.S. stockpile of critical materials and deploying large-scale energy storage systems that power data centers and the nation’s grid.
About the role
This role focuses on moving away from rigid, hardware-centric infrastructure toward a resilient, unified, and software-defined energy storage architecture. You will be instrumental in making varied OEM packs operate seamlessly off-vehicle, turning proprietary automotive components into reliable building blocks for the grid. You will serve as the lead Software POC for external OEMs, steering the critical technical discussions necessary to successfully adapt and integrate their battery systems into our architecture
What they're looking for
- Architectural Integration: Design and deploy translation layers and software gateways to seamlessly integrate vendor-off-the-shelf and second-life OEM battery packs into our centralized energy storage system
- Technical Mastery: Proven track record in controls and software engineering with a deep, practical understanding of lithium-ion battery architectures, external BMS software, and pack-level integration
- Modern Tech Stack: Proficiency in modern software engineering practices and languages (Rust, Python, C/C++)
- Protocols & Networking: Expertise in automotive and industrial communication networks (CAN, LIN, Automotive Ethernet) and their associated diagnostic toolchains
- Adaptive Problem Solving: Exceptional capability to reverse-engineer, troubleshoot, and adapt complex OEM electro-mechanical software systems for novel applications in circular energy ecosystems

About Redwood Materials
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.
About the Role
At Redwood, we are architecting the future of grid-scale energy storage and circular energy ecosystems. As we rapidly scale our stationary Battery Energy Storage Systems (BESS), we are looking for a Battery Software Integration Engineer to build the bridge between diverse, second-life automotive batteries...
