Job summary

Delart seeks a Battery Failure Analysis Engineer to operate and maintain CT scan systems for analyzing battery cells, modules, and packs. You will translate imaging results into design, quality, and validation actions while collaborating with cell manufacturing and failure analysis teams.

With 5+ years in battery failure analysis, you will handle teardowns, data interpretation, and reports, ensuring safety and compliance across CT operations and lithium‑ion handling.

Qualifications

• 5+ years experience in battery failure analysis with background in cell design and structure
• Comprehensive understanding of cell manufacturing processes (electrode coating, calendaring, winding/stacking, electrolyte filling, formation cycling)
• Experience operating and interpreting results from CT/X-ray inspection systems for battery analysis
• Advanced training and adherence to safety protocols for CT system operation and lithium‑ion handling

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, inclusions, electrolyte dry‑out, swelling, and mechanical damage
• Compile failure analysis reports with annotated images, measurements, and actionable conclusions for cross‑functional teams
• Conduct battery teardowns and complementary failure analysis in dry room or glovebox per safety rules
• Maintain CT system calibration and coordinate with vendors for service or repairs
• Ensure compliance with radiation, laser, and battery safety standards during CT operations
• Support battery validation by correlating CT imaging with electrical, thermal, and mechanical test data

About the job

Delart is home to a team of world-class engineers and project leaders dedicated to developing the next generation of advanced networking technologies, consumer devices, and innovative technology solutions. Trusted by some of the world’s leading technology companies, we deliver highly scalable, mission-critical solutions that power both consumer and business applications globally. Since our founding in 2017, we have been at the forefront of designing cutting-edge networking, telecommunications, and consumer products, while driving end-to-end project execution and creating transformative technology applications.

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.

CA Base Pay: $125,000 USD - $170,000 USD
