Position Overview:

The Plant Quality Manager is a critical operations leader responsible for owning plant quality end-to-end — strategy, execution, and results. This role leads all aspects of quality management within an EV battery manufacturing facility, ensuring products meet internal specifications, customer requirements, and applicable regulatory and safety standards. The Plant Quality Manager drives a culture of continuous improvement, builds and sustains high-performing quality teams, and serves as the key quality partner to production, engineering, supply chain, and customers.

This is a highly visible, floor-present leadership role. Success requires the ability to operate simultaneously at a strategic level — designing and executing the plant quality strategy — and at a hands-on level, actively engaging on the production floor to identify defects, drive root cause resolution, and ensure corrective actions are implemented and sustained.

• Review performance daily and weekly; adjust actions proactively based on data trends —

Root Cause Analysis & Continuous Improvement

• Personally sponsor and lead major corrective actions; ensure 8D and 5-Why analyses are thorough — not surface level
