Senior Battery Systems Engineer

Redwood Materials • San Francisco, CA

4h • $160,000 - $215,000 • Onsite

About The Position

Redwood Materials is hiring a Senior Battery Systems Engineer within its Energy Storage engineering function. The role leads cross-functional integration of new OEM battery packs into stationary energy storage systems, independently owning system architecture, requirements, and interface definitions for each integrated pack. The engineer aligns mechanical, electrical, controls, power electronics, and software engineering teams on a common technical baseline, and serves as the technical point of contact for OEMs and suppliers as automotive packs are adapted to off-vehicle duty cycles. The role is reviewed at critical design decision points and is accountable for ensuring system-level requirements are complete, testable, and verified.

This is a fully on-site position at 100 Hooper, with occasional travel to sites and vendors. Travel may be up to 10% of the time. The position is full-time. The California salary range is $160,000–$215,000 USD, with compensation commensurate with experience.

Requirements

• 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 of experience.
• Working knowledge of lithium-ion battery pack architecture, battery management systems, and pack communication protocols such as CAN, Modbus, and 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 the time.

Responsibilities

• Lead cross-functional integration of new OEM battery packs from technical intake through validation and deployment.
• Own system-level architecture, performance, and functional requirements for integrated packs, and derive subsystem and component requirements with design engineers.
• Define and maintain mechanical, electrical, communication, and software interfaces between OEM packs and the energy storage system.
• Lead technical discussions with OEMs and suppliers to obtain pack data, resolve integration issues, and agree on engineering solutions.
• Lead DFMEAs, hazard analyses, and risk assessments for integrated packs, and track mitigations through closure.
• Ensure integrated systems comply with applicable UL and industry standards.
