• Operate, inspect, calibrate, and maintain pilot-line equipment, tooling, dry-room environments, glove boxes, and related fabrication systems.
• Assist with Design of Experiments (DOEs) to evaluate process variables and improve cell consistency, yield, uniformity, and performance.
• Conduct in-process quality checks, including electrode thickness, coating or loading consistency, component alignment, and pouch seal integrity, and record results in applicable tracking systems.
• Investigate common fabrication issues, such as coating defects, delamination, misalignment, incomplete wetting, and sealing problems, and support corrective actions under senior engineering guidance.
• Maintain accurate assembly travelers, process records, equipment logs, SOPs, safety documentation, and other technical documentation for new materials, chemistries, and cell formats.

Required:

• Bachelor’s degree in Materials Science, Chemical Engineering, Mechanical Engineering, Electrical Engineering, or a related field, or equivalent practical experience.
