About the role
This role runs the battery characterization program for second-life battery systems that supply power to data centers. The engineer decides what gets tested and how, and turns open-ended performance and compliance questions into test protocols. The resulting data feeds site operating parameters, battery models and control algorithms.
What you'll do
- Turn performance and compliance questions into test matrices, channel allocations and schedules.
- Run several test and screening campaigns at once across cell, module and pack level, including cycler programming, monitoring and failure root-cause analysis.
- Recommend and plan lab equipment purchases such as cyclers and chambers, fixture design and channel capacity as the program grows.
- Analyze test results and present clear conclusions to technical and non-technical audiences to support pack qualification decisions.
- Improve test methods and write automation scripts to get more insight from limited channels and time.
- Work with the battery software and data engineering team to define and validate automated characterization workflows.
Requirements
- BS or MS in mechanical, chemical, materials, electrical engineering or a related field.
- At least 3 years of relevant experience.
- Solid understanding of lithium-ion cell behavior, operating limits, failure modes and degradation mechanisms.
- Hands-on electrochemical characterization experience, such as HPPC, EIS, dQ/dV analysis and cycle life testing.
- Data analysis and scripting skills in Python or MATLAB.
- Experience programming and troubleshooting battery cycler platforms such as Arbin, Maccor or Neware.
Nice to have
- Experience using AI coding assistants.
- Background in EV battery pack qualification or validation programs.
- Familiarity with battery safety and compliance standards such as UN38.3, UL2580 and UL1974.
