Abuse Testing Technician

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.

This is a hands-on role in which you will help tear down battery packs, set up tests, harness systems, document results, and maintain a clean and organized lab environment.

Responsibilities will include: 

• Perform abuse tests on battery modules and packs, including thermal, electrical, and mechanical stress testing.
• Disassemble and tear down battery packs to analyze internal components, failure modes, and degradation patterns.
• Follow detailed test setup instructions to ensure accurate and repeatable testing.
• Install sensors, instrumentation, and harnessing on battery packs and test fixtures.
• Document test results with clear, detailed notes, photos, and reports.
• Work closely with engineers and safety teams to execute testing protocols safely and effectively.
• Maintain a clean and organized test lab, ensuring tools and equipment are properly stored and maintained.
• Assist in data collection and analysis to support battery performance and safety evaluations.
• Follow strict high-voltage safety protocols to ensure personal and team safety during all test procedures.
• Collaborate with cross-functional teams to troubleshoot issues and improve testing processes. 

Desired Qualifications: 

• Experience working with high-voltage systems, battery modules, or power electronics is highly preferred.
• Hands-on experience with mechanical assembly, disassembly, and electrical harnessing.
• Strong understanding of safety procedures and PPE requirements when working with hazardous materials and high-voltage environments.
• Ability to read and follow technical drawings, schematics, and written test procedures.
• Strong organizational and documentation skills to accurately record test results.
• Willingness to work in a lab/testing environment, with exposure to thermal and mechanical stress testing conditions.
• Experience with multimeters, oscilloscopes, and other electrical testing equipment is a plus.
• Prior experience in battery testing, automotive, aerospace, or energy storage industries is a plus

Physical requirements:

• Ability to lift and work with hand tools for extended periods.

Working conditions: 

• Comfortable working in a fast-paced, team-oriented environment with shifting priorities.

The position is full-time. Compensation will be commensurate with experience.
