Battery EOL Quality Engineer — Formation & Test Lead

GM; Warren (MI); On-site; USD 130,000 - 180,000; Full time

Job summary

GM is seeking a Formation and EOL Quality Engineer to lead product and process quality assurance for formation, aging, and end-of-line testing at the Battery Cell Development Center. You will define acceptance criteria, control strategies, reaction plans, and lot disposition standards while partnering with process engineering and manufacturing to prevent defects and drive corrective actions.

You will own quality for new battery chemistry campaigns, maintain control plans for critical

Qualifications

• 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.
• Demonstrated experience with battery cycling equipment.
• Practical experience using CT scanning or other advanced internal characterization methods such as SEM.
• Strong working knowledge of quality and statistical tools, including SQC, MSA, and other core quality tools.
• Proven ability to interpret product and process requirements in quality documentation using electrochemical and material science fundamentals.
• 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.

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.
• Integrate CT and other scanning techniques into end of line quality control, characterizing internal features linked to formation and cell performance.
• 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.
• Coordinate measurement system studies (e.g., GR&R / MSA) for key in‑line and offline formation and end of line measurements.
• Ensure measurement systems, test methods, and inspection technologies are capable and suitable for product acceptance decisions.
• Provide quality sign‑off for hold, release, potential rework, or scrap decisions for formation and EOL lots.
