Are you passionate about batteries and the data that reveals how they perform, age, and fail? We're building a new cell test lab from the ground up, and we're looking for a Cell Test Engineer to help design it, stand it up, and run it. In this role you will own the full lifecycle of cell-level testing: designing test plans, building test coupons, executing aging and characterization campaigns, and turning raw tester output into clear, trustworthy results that drive decisions across our cell and power teams.

This is a hands-on engineering role for someone who thrives on both the physical work of the lab and the digital work of the data pipeline. You'll spec and commission new test equipment, define the standards and processes for a growing lab, and partner with vendors to keep our testers running. You'll also lean into modern tooling, using AI-assisted workflows to dive deep into large datasets. If you take pride in organization, precision, and building things right the first time, this role gives you the opportunity to set the foundation for how our team tests batteries for years to come.

Key job responsibilities
• Own the execution of cell-level test campaigns end to end: build coupons, prepare and load cells, author and validate tester scripts, run aging (cycle and calendar), capacity checks, and characterization, and keep campaigns on schedule across a fleet of testers.
• Perform battery qualification and characterization testing across a broad range of methods and specialized equipment, including but not limited to vacuum and helium bomb leak testing, ultra-high-precision coulometry (UHPC), rapid self-discharge evaluation, batch capacity testing, nondestructive inspection (CT, microscopy), DPA, abuse testing (thermal runaway, ARC, calorimetry, etc).
• Spec, procure, install, and commission new test and inspection equipment for the new lab, developing commissioning checklists that verify equipment across its full operating range and load before real testing begins, and partnering with vendors on selection, troubleshooting, and support.
• Monitor equipment daily, troubleshoot hardware and software issues, and document issues, resolutions, and test status in Jira and tracking tools.
• Process, validate, and report on test data using Python and AI-assisted workflows; generate plots and summaries, flag data-integrity concerns, and communicate results to cell and power teams.
BASIC QUALIFICATIONS
- Experience managing lab resources, equipment, and supplies
- Bachelor's degree in engineering, chemistry, physics, materials science, or a related technical field, or equivalent hands-on experience.
- Demonstrated organization and attention to detail in managing multiple concurrent tasks, records, and datasets.
PREFERRED QUALIFICATIONS
- Experience working with equipment suppliers, laboratories and manufacturing plants
- Hands-on experience with battery qualification and specialized test/inspection equipment such as vacuum and helium bomb leak testing, ultra-high-precision coulometry (UHPC), rapid self-discharge evaluation, batch capacity testing, CT and SEM nondestructive inspection, and glovebox destructive teardowns.
- Familiarity with battery cyclers and test systems such as Arbin or Neware, including script authoring and equipment commissioning.
- Understanding of battery fundamentals: how cells degrade, how to characterize state of health, and how to qualify cells against requirements.
- Experience specifying, procuring, installing, and commissioning lab or test equipment, and defining SOPs and commissioning checklists.
