Redwood Materials, founded in 2017 by JB Straubel (Tesla co-founder and former CTO), is North America's largest lithium-ion battery recycler and a leader in second-life battery deployment for AI data centers. The company is profitable and positioned to lead a market projected to grow 20–50x over the next decade.
This Staff Applications Engineer role serves as the technical bridge between Redwood's Battery Energy Storage System (BESS) product design team and the deployment, construction, and service teams who install and maintain products in the field. Embedded within the product design organization, you will translate field experience into design requirements and help drive the technical roadmap toward products that are cheaper and easier to deploy and service.
Key responsibilities include:
- Represent deployment, construction, and service needs within the product design team, translating field feedback into clear design requirements
- Guide the BESS technical roadmap by identifying and prioritizing design changes that reduce installed cost, install time, and service burden
- Drive new product and design improvements in partnership with mechanical, electrical, and firmware engineers
- Develop and execute test plans with test engineering to validate installability and serviceability
- Develop installation and service procedures, tooling, and equipment in partnership with EPC and service teams
- Support field deployments and service events on-site to diagnose issues, gather data, and close the loop on design gaps
- Advise cross-functional stakeholders on system-level technical tradeoffs affecting deployment and serviceability
This is a fully on-site role at 100 Hooper in San Francisco, with approximately 25% travel to project sites and partners. Success requires deep system-level technical understanding combined with practical knowledge of how installers and service technicians actually work.
Requirements:
- Bachelor's degree in Mechanical or Electrical Engineering preferred, or equivalent experience
- 8+ years of experience in industrial battery storage or solar installation, design, or deployment
- Deep system-level understanding of BESS or PV systems, including DC and AC electrical architecture and applicable codes (e.g., NEC)
- Experience as a licensed or journeyman electrician is a plus
- Mechanical design experience (e.g., CAD) is a plus
- Demonstrated ability to work independently, set priorities, and influence cross-functional teams without direct authority
- Ability to travel up to 25% of the time, including to active construction sites
