About the role
- The engineer drives root cause resolution, qualification rigor, and continuous improvement across a supply chain where safety and long-term degradation performance are mission critical.
- The Senior Supplier Quality Engineer owns and drives the technical rigor and effectiveness of the supplier quality program for our battery energy storage systems (BESS) - spanning all aspects of the BESS, such as the modules, packs, battery management systems (BMS), thermal management, enclosures, and power conversion components.
- This role is the technical authority linking engineering, manufacturing, and the global supply base, ensuring supplier materials and processes meet safety, performance, and reliability requirements for grid-scale and behind-the-meter energy storage.
Responsibilities
- Own the technical strategy and rigor of the supplier quality program both for the BESS and BOS (balance-of-system) suppliers, setting inspection criteria, sampling plans, and acceptance methods
- Lead supplier qualification and PPAP/APQP (or equivalent) for new parts, designs, and manufacturing process changes, including first-article and pilot-run approval
- Drive root cause analysis (8D, 5-Why, fishbone) for supplier-related nonconformances and verify corrective action effectiveness
- Conduct and lead supplier audits and process capability assessments at manufacturing sites; develop supplier scorecards and drive improvement plans
- Lead containment and disposition decisions for nonconforming supplier material (MRB), including cell/pack quarantine and safe-handling protocols
- Support supplier corrective action tied to field returns, warranty claims, and degradation/safety incident investigations
- Mentor quality engineers and build technical capability within the SQE team
- Partner with engineering to define incoming inspection requirements, critical-to-quality (CTQ) characteristics, and acceptance criteria for all supplied parts or services
Requirements
- Must be able to remain in a stationary position 50% of the time and occasionally move about inside the office to access file cabinets, office machinery, etc.
