Overview

Join our Team as a hands-on CT Technician, responsible for full-scope operation and maintenance of 3D X-ray computed tomography (CT) and 2D X-ray systems for battery cells, modules, and packs. Your core focus will be executing CT scans, analyzing data, and collaborating with engineering teams to validate Li-ion battery cells for next-generation hardware, ensuring internal defects and changes over cell lifetime are thoroughly understood and communicated.

Responsibilities

• Prepare, load, and scan battery cells, modules, packs, and field returns from the request queue, prioritizing new-product Li-ion cells.
• Independently operate the Waygate Phoenix V|tome|x CT system (plus any 2D X-ray systems), including all sample preparation, fixturing, scan parameter optimization, volume reconstruction, and scheduling in the Fremont Lab.
• Analyze CT data in VGStudio MAX to identify and image internal defects and features, including electrode misalignment, jellyroll deformation, welding issues, foreign particles, electrolyte depletion, swelling, and mechanical damage.
• Perform 2D X-ray inspection of battery management units (BMUs) and correlate findings with electrical/mechanical/abuse test data when needed.
• Ensure meticulous data records, generate detailed FA reports with annotated images and measurements, and share key findings in the tracking system for design, quality, and validation teams.
• Maintain CT system calibration, perform quality checks, routine troubleshooting, and coordinate with vendors for repair or service.
• Uphold and document all lab 5S, radiation safety, and battery safety protocols; properly handle damaged, swollen, or charged Li-ion cells.
• Maintain chain of custody for field returns and prototype batteries.
• Support other battery validation team members as needed with electrical testing, electrochemical analysis, and/or glovebox teardowns.

Minimum Qualifications

• Associate degree in materials science, nondestructive testing (NDT), radiography, or electrical/mechanical engineering technology, or equivalent practical experience.
• 2+ years operating industrial CT/micro-CT or X-ray inspection systems (e.g., Waygate, Nikon, Zeiss, North Star, Bruker).
• Hands-on experience performing CT data analysis in VGStudio MAX.
• Strong knowledge of Li-ion battery cell construction and recognition of CT-visible failure modes.
• Ability to lift 25 lbs and work on-site in a lab environment.
• Excellent documentation and organizational skills.

Preferred Qualifications

• ASNT NDT Level I/II certification in Radiography/CT.
• Experience operating and maintaining gloveboxes, Maccor battery cyclers, and other battery testing instrumentation.
• Hands-on teardown skills for pouch, prismatic, and cylindrical Li-ion batteries.
• Familiarity with high-throughput validation labs using ticketing and results-tracking systems.
• Experience with additional battery failure analysis techniques (e.g., SEM/EDS, cross-sectioning, optical microscopy).

Benefits

Delart provides competitive benefits and compensation across all regions where we operate. In the United States, our benefits package includes premium PPO and HMO medical insurance, dental and vision coverage, flexible spending accounts (FSA), life insurance, short- and long-term disability insurance, a company-matched 401(k) plan, and a generous paid time off policy.
