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.
Essential duties
As the lead of the Manufacturing Test team, you will manage a growing team of interdisciplinary engineers to support high-volume complex validation of energy products at Redwood Materials. Your role will include cultivating cross-functional collaboration across mechanical, electrical, and software engineering domains to ensure robust product validation. You'll influence design-for-test initiatives and define team scope as it evolves.
Responsibilities will include:
- Lead/support design, bring-up, and validation of PCBA and TLA/EOL functional testers
- Coordinate timelines, budgets, and company priorities across stakeholders (Manufacturing, Operations, Supply Chain, Design)
- Collaborate with system integrators, contract manufacturers, and equipment vendors to implement and qualify test stations
- Lead/support debug of manufacturing test failures, working cross-functionally to resolve issues
- Drive continuous improvement of test processes, including coverage expansion, cycle-time reduction, parallelization opportunities, power & cooling efficiency optimization, station reliability, and data quality.
- Ensure manufacturing test readiness for new product introduction, including test specifications, validation plans, GR&R studies, station acceptance, and product release criteria.
- Help establish scalable standards and best practices for the team's development across Redwood's rapidly growing product portfolio
Desired Qualifications:
- Bachelor's degree in Mechanical Engineering, Electrical Engineering, Mechatronics, or a related field
- 5+ years of relevant industry experience
- 2+ years of people management experience
- Comfortable with industrial automation, PLC, and test automation
- Familiarity with design-for-manufacturing and design-for-test best practices
- Demonstrated ability to read, create, and review electrical schematics and mechanical drawings
- Experience working with high-voltage systems (400–2000VDC and 480-800VAC)
- Strong hands-on debugging skills, with comfort working across disciplines (mechanical, electrical, software)
- Experience with test equipment including DAQs, power supplies, sensors, etc.
