The posting, in Redwood Materials's own words
archived Sep 2, 2026About Redwood Materials Redwood is localizing a global battery supply chain that seamlessly integrates recovery, reuse, and recycling — keeping critical minerals in circulation and driving the energy transition. Founded in 2017, we’re delivering low-cost and large-scale energy storage and producing battery materials in the U.S. for the first time, all from batteries we already have. Abuse Testing Technician Redwood Materials is seeking an Abuse Test Technician to support high-voltage battery testing, teardown, and failure analysis. This role will focus on executing safety-critical test procedures, handling battery packs and modules, and assisting in research efforts to improve battery durability and sustainability. The ideal candidate has experience working with high-voltage systems, test setups, and safety procedures, with a strong mechanical aptitude and attention to detail. 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.
