Reliability Engineer, Energy Storage

Reliability Engineer, Energy StorageSan Francisco, California, United StatesRedwood 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.Reliability Engineer, Energy StorageAs an early member of a new engineering team, you will be responsible for defining system reliability requirements, generating damage models, and characterizing the reliability of our new product. You will work cross-functionally to define requirements, analyze designs, and design tests to meet high reliability standards in real-world conditions, including both electrical and mechanical failure modes.You're a doer, excited about getting your hands dirty and working in a dynamic, fast-paced setting, and want to shape a new department at Redwood.Responsibilities will include:Define and own the reliability strategy for hardware products with complex printed circuit board assemblies (PCBAs) and electromechanical systemsPlan and execute reliability tests such as HALT, thermal cycling, vibration, drop, humidity, ingress protection (IP) testing, and power cyclingCollaborate with cross-functional teams to define design-for-reliability (DfR) requirements and drive root cause analysis for test failuresTrack reliability KPIs and deliver reliability insights to guide design improvements and product decisionsDevelop accelerated life test models and support FMEA and DFMEA processesAnalyze reliability data using Weibull, log-normal, and other statistical models to predict field performanceWork closely with engineering teams to establish reliability gates through program stages (A/B/C/D)Support failure analysis (FA) efforts using tools like X-ray, cross-sectioning, and SEM/EDX to identify failure mechanisms in PCBAsContribute to continuous improvement efforts across reliability processes, lab capabilities, and test methodologiesAuthor reports / document findingsDesired Qualifications:Bachelor's or Master's degree in Electrical Engineering, Mechanical Engineering, Materials Science, or a related field5 + years of experience in hardware reliability engineering, preferably in industries like energy, EV, consumer electronics, or aerospaceDeep knowledge of electronic and mechanical failure mechanisms (e.g., solder fatigue, corrosion, delamination, sealing failures, thermal expansion mismatch, material fatigue, etc.)Proficiency in statistical analysis tools (e.g., Minitab, JMP, or Python)Experience with reliability lab equipment and test setup designKnowledge of reliability warranty analysis and reliability prediction methodsWorking knowledge of failure analysis techniques such as optical microscopy, SEM, CSAM, X-ray, cross-sectioning, and EDXA passion for sustainability and making the world a better place!In accordance with California pay transparency laws, the salary range for this position is listed below.
