- Develop and execute test plans to probe cell-level failure modes including internal shorts, capacity fade, swelling, thermal runaway, and electrolyte degradation
- Fabricate coin and low-capacity pouch cells, within glovebox environment as well as production-relevant production line fault injections
- Conduct in-depth analysis on battery cells using advanced diagnostic tools (e.g., SEM, CT, EIS, XRF, etc)
- Perform electrical and electrochemical characterization (cycling, impedance spectroscopy, charge/discharge profiling) to identify performance anomalies
- Document findings with clear, actionable reports, including root cause analysis, failure mechanisms, and mitigation recommendations
- Collaborate with materials scientists, process engineers, and manufacturing teams to implement corrective actions and prevent recurrence
- Support product and cell test validation programs

- Degree in Chemistry, Material Science, Chemical Engineering or equivalent experience
- 2+ years of hands-on experience in battery cell design, testing, failure analysis, or R&D
- Proficiency with battery testing equipment (e.g., Arbin, Neware, Bio-Logic, etc)
- Proficiency with data analysis tools (Python, MATLAB, Excel)
- Understanding of lithium-ion battery chemistry and failure mechanisms
- Understanding of non-destructive and destructive analytical techniques (CT, XRF, SEM-EDS, DSC, TGA, FTIR, etc.)
- Excellent problem-solving, communication, and documentation skills
- Ability to work in a fast-paced, cross-functional environment with attention to detail and safety
