Overview

Join our team as a Battery Failure Analysis Engineer, with hands-on responsibility for operating and maintaining a CT scan system used to analyze battery cells, modules, and packs. This role is central to uncovering and interpreting internal defects through advanced imaging, directly supporting root-cause investigations across various battery form factors. You will serve as a technical bridge between cell manufacturing, battery design, and failure analysis, generating actionable insights for design, quality, and validation efforts.

Responsibilities

Independently operate CT scan equipment for battery cells, modules, and packs, including sample preparation, fixturing, scan parameter selection, and scheduling in a lab environment.

Interpret 2D and 3D CT images to identify defects such as electrode misalignment, jellyroll deformation, welding issues, foreign material inclusions, electrolyte dry-out, swelling, and mechanical damage.

Compile clear and detailed failure analysis reports, including annotated images, measurements, and actionable conclusions for cross-functional teams in design, quality, and validation.

Conduct battery teardowns and complementary failure analysis in dry room or glovebox settings when needed, ensuring adherence to safety protocols.

Maintain CT system calibration, perform routine troubleshooting, and coordinate with equipment vendors for service or repairs.

Enforce strict compliance with radiation, laser, and battery safety standards during CT scan operation and handling of potentially hazardous or damaged lithium-ion cells.

Support battery validation activities by correlating CT imaging results with electrical, mechanical, and abuse testing data.

Minimum Qualifications

Bachelor’s degree in Materials Science, Mechanical Engineering, Chemical Engineering, or a closely related discipline.

5+ years of experience in battery failure analysis, with a deep background in cell design and structure.

Comprehensive understanding of cell manufacturing processes, including electrode coating, calendaring, winding/stacking, electrolyte filling, and formation cycling.

Demonstrated experience operating and interpreting results from CT/X-ray inspection systems for battery analysis.

Advanced training and adherence to safety protocols for both CT system operation and lithium-ion cell handling.

Preferred Qualifications

10+ years total experience in battery failure analysis and cell engineering roles, spanning multiple cell chemistries and formats (cylindrical, pouch, prismatic).

Proficiency in conducting detailed cell teardowns and failure investigations across a range of battery types, including hard-can designs.

Familiarity with additional analytical techniques, such as SEM/EDS, cross-sectioning, and optical microscopy for root-cause investigations.

Experience with battery validation, including electrical, thermal, and mechanical abuse testing methodologies.

Ability to operate independently in a laboratory environment and effectively communicate technical findings to diverse engineering and development teams.
