Job Description
The Reliability Engineer, Energy Storage at Redwood Materials is responsible for defining and executing reliability strategies for battery hardware products, conducting tests, analyzing failure mechanisms, and collaborating with cross-functional teams to ensure high reliability and support product development in a fast-paced, sustainability-focused environment.
Key Responsibilities
- Define and own the reliability strategy for hardware products with complex PCBAs and electromechanical systems
- Plan and execute reliability tests such as HALT, thermal cycling, vibration, drop, humidity, ingress protection, and power cycling
- Collaborate with cross-functional teams to define design-for-reliability (DfR) requirements and analyze test failures
- Track reliability KPIs and provide insights to guide design improvements and product decisions
- Develop accelerated life test models and support FMEA and DFMEA processes
- Analyze reliability data using statistical models to predict field performance
- Support failure analysis efforts using tools like X-ray, cross-sectioning, SEM, and EDX to identify failure mechanisms
- Contribute to continuous improvement of reliability processes, lab capabilities, and testing methodologies
Requirements
- Bachelor's or Master's degree in Electrical Engineering, Mechanical Engineering, Materials Science, or a related field
- 5 years of experience in hardware reliability engineering, preferably in industries like energy, EV, consumer electronics, or aerospace
- Deep knowledge of electronic and mechanical failure mechanisms such as solder fatigue, corrosion, delamination, sealing failures, thermal expansion mismatch, and material fatigue
- Proficiency in statistical analysis tools such as Minitab, JMP, or Python
- Experience with reliability lab equipment and test setup design
- Knowledge of reliability warranty analysis and reliability prediction methods
- Working knowledge of failure analysis techniques including optical microscopy, SEM, CSAM, X-ray, cross-sectioning, and EDX
- Ability to define and own the reliability strategy for hardware products with complex printed circuit board assemblies (PCBAs) and electromechanical systems
- Ability to plan and execute reliability tests such as HALT, thermal cycling, vibration, drop, humidity, ingress protection (IP) testing, and power cycling
- Experience collaborating with cross-functional teams to define design-for-reliability (DfR) requirements and drive root cause analysis for test failures
- Ability to track reliability KPIs and deliver reliability insights to guide design improvements and product decisions
- Experience developing accelerated life test models and supporting FMEA and DFMEA processes
- Ability to analyze reliability data using Weibull, log-normal, and other statistical models to predict field performance
- Experience establishing reliability gates through program stages A, B, C, D
- Support failure analysis efforts using tools like X-ray, cross-sectioning, SEM, and EDX to identify failure mechanisms in PCBAs
- Contribute to continuous improvement efforts across reliability processes, lab capabilities, and test methodologies
