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.
Position Summary:
The Senior Battery Systems Engineer leads the cross-functional integration of new OEM battery packs into the stationary energy storage system architecture within the Energy Storage engineering function. The role independently owns the system architecture, requirements, and interface definitions for each integrated pack, aligning mechanical, electrical, controls, power electronics, and software engineering on a common technical baseline. This role serves as the technical point of contact for external OEMs and suppliers on pack-level integration, adapting automotive packs to off-vehicle duty cycles with limited precedent. The position is reviewed at critical design decision points and is accountable for system-level requirements being complete, testable, and verified. This is a fully on-site role at 100 Hooper, with occasional travel to sites and vendors.
Essential Duties and Responsibilities
- Leads cross-functional integration of new OEM battery packs from technical intake through validation and deployment
- Owns system-level architecture, performance, and functional requirements for integrated packs and derives subsystem and component requirements with design engineers
- Defines and maintains mechanical, electrical, communication, and software interfaces between OEM packs and the energy storage system
- Leads technical discussions with OEMs and suppliers to obtain pack data, resolve integration issues, and agree on engineering solutions
- Leads DFMEAs, hazard analyses, and risk assessments for integrated packs and tracks mitigations to closure
- Ensures integrated systems comply with applicable UL and industry standards
Skills, Knowledge, and Abilities
- Bachelor's degree in Electrical Engineering, Mechanical Engineering, or a related field and 5+ years of systems or design engineering experience, or a Master's degree and 3+ years
- Working knowledge of lithium-ion battery pack architecture, battery management systems, and pack communication protocols (CAN, Modbus, Ethernet)
- Experience with energy storage systems, hybrid or electric powertrain development, or PV system development
- Ability to write clear, testable engineering requirements and manage them in a requirements management tool
- Effective communication skills to lead technical alignment across engineering disciplines and with external OEMs
- Ability to travel to sites and vendors up to 10% of time
