End of Line (EOL) Quality Engineer – Battery Cell Development Center

About the role

The Formation and EOL Quality Engineer is responsible for establishing and leading product and process quality assurance for formation, aging, and end-of-line testing within the Battery Cell Development Center (BCDC).

Responsibilities

• Own process quality for new battery chemistry campaigns from formation through end-of-line testing including automated material movements in the area.
• Update and maintain control plans for critical quality characteristics in formation and end of line testing such as charge/discharge profiles, gas evolution, capacity, impedance, leakage, and voltage decay behaviors in the finished cell.
• Lead data-driven monitoring for end of line testing and cell cycling for lot-to-lot verification.
• Execute end of line test quality and inspection strategies to ensure that finished cells meet expected performance targets including validation of end of line vision systems.
• Create and maintain other quality documentation (process flow diagrams, work instructions, risk analyses, sampling plans etc.) for the formation and end of line area.
• Career development and professional growth opportunities are available to those who demonstrate a commitment to excellence in their work and a desire to contribute to the success of the organization.

Requirements

• Bachelor’s degree in chemistry, materials science, chemical engineering, or a closely related field.
• 5+ years of experience in a quality role for battery manufacturing or pack design, focusing on formation and end of line.
• Hands-on experience in cell or module production environments, focusing on formation, aging, and end of life testing.
• Understanding of lithium-ion cell electrochemistry, formation, electrode/electrolyte interfaces, and cyclical degradation mechanisms.
• Experience validating end of line vision systems and automated material movements.
• Experience working with large data sets and systems for finished cell lot release.
• Practical experience using CT scanning or other advanced internal characterization methods such as SEM.
• Strong working knowledge of quality and statistical tools, including statistical process control, measurement systems analysis (MSA), and other core quality tools.
• Demonstrated experience with battery cycling equipment.
• Demonstrated technical leadership, including mentoring, cross-functional influence, and the ability to drive complex, multi-variable problems to closure.
• Effective communication skills, capable of explaining complex electrochemical concepts to diverse technical and operational audiences.

Qualifications

• Advanced degree in electro-chemistry, Materials Science and Engineering, or a closely related field.
• Experience integrating new battery chemistry formation and aging data with CT and spectroscopy techniques.
• Familiarity with gigafactory scale manufacturing systems used to manage large cycling and test datasets to disposition finished cells.
• Experience implementing new quality systems and testing strategies for quality inspection tools and equipment in pilot environments.
• Experience with advanced analytics (e.g., multivariate analysis, machine learning on cycling and CT data) to identify patterns linked to early cell failures.
