About the role
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 : Redwood Materials is currently searching for a Service Engineer to join as an early member of a new engineering team working on our Battery Energy Storage System product line. You will be responsible for resolving complex technical issues across deployed Battery Energy Storage Systems (BESS). This role supports an Operations and Maintenance (O&M) organization that performs routine monitoring, preventive maintenance, and first-line troubleshooting. Service Engineering serves as the technical escalation path for O&M, owning deep diagnostics, system-level failure analysis, and engineering-driven corrective actions. The Service Engineer ensures safe, reliable, and high-performing asset operation by bridging field operations and engineering, translating operational issues into engineering solutions, and feeding field learnings back into product and system design. This role has the potential of growing into leadership as the team grows. The ideal candidate is highly self-driven, adaptable to a startup environment, and eager to take on both technical and leadership challenges. You’re a leader and a doer, excited about working in a dynamic, fast-paced setting, and want to shape the electrical engineering function within a new department at Redwood. Essential Duties and Responsibilities: • Act as the primary technical escalation point for the O&M organization for issues beyond standard operating procedures • Define clear handoff criteria, escalation thresholds, and response expectations between O&M and Service Engineering • Lead, mentor, and scale a team of Service Engineers providing tier-2 and tier-3 technical support • Own investigation and resolution of complex electrical, controls, software, thermal, and system-integration issues • Translate field and O&M feedback into actionable requirements for Product, Systems, and R&D Engineering teams • Drive improvements in system serviceability, reliability, and maintainability through design and process changes • Own advanced service documentation including troubleshooting guides, decision trees, and service bulletins • Develop technical training materials and support O&M team upskilling on new systems, upgrades, and known issues Desired Qualifications : • Bachelor’s degree in Electrical Engineering , Mechanical Engineering, or a related technical discipline • 3+ years of experience supporting complex electromechanical or power electronics systems (BESS, renewable energy, industrial systems) • Deep understanding of BESS system architecture, including batteries, PCS/inverters, EMS, thermal management, and protection systems • Proven experience operating in a tiered support model (O&M → Service Engineering → Product Engineering) • A Passion for sustainability and making the world a better place! Physical Requirements: • Ability to perform the essential job functions consistent safely and successf
