Senior Staff Quality Engineer, Battery Manufacturing

• Manage IQC, IPQC, OQC, and ORT across battery cell production lines • Drive quality readiness at the Contract Manufacturer (CM) for development builds (EVT/DVT/PVT) and mass production ramp, including establishing inspection and hold/release protocols • Lead root cause and corrective action (RCCA) investigations for quality escapes; present findings and closure plans to internal and CM leadership as required • Collaborate with cell engineering and teams to define and implement appropriate quality control, inspection, and metrology stations across the full cell production process (electrode coating and calendering, winding/stacking, electrolyte filling, formation, aging, and final test) • Define and monitor electrochemical quality metrics, identify process signals and drive SPC implementation • Conduct periodic factory quality reviews covering yield, scrap, defect Pareto, and process capability trends • Prepare OK-to-Ship and lot dispositioning documentation for new product launch and ongoing mass production • Develop and maintain risk assessments (PFMEA) for battery manufacturing processes; implement control plans and reaction plans for identified risk items • Support DFM reviews with cell design and product teams; conduct tolerance analysis for electrode stack, cell can/pouch dimensions, and assembly fit to ensure process capability against specification • Develop and execute module and cell reliability test plans (cycle life, calendar aging, thermal abuse, mechanical) during NPI and MP, in coordination with internal engineering teams • Ensure manufacturing process controls are sufficient to maintain compliance with applicable safety and certification standards (IEC 62133, UN 38.3, UL 1642, GB/T equivalents as applicable) at the production leve • 30–40% international travel to CM sites in Asia required

In this highly visible role, you will have the opportunity to make a significant impact on next-generation battery products and establish quality systems that scale from development through high-volume production. You will serve as the critical bridge between our internal cell engineering and product teams and the factory floor—enabling the reliable, high-yield manufacture of advanced battery cells. • Minimum of 12 years of related experience with a Bachelor’s degree; or 8 years and a Master’s degree; or a PhD with 5 years experience; or equivalent experience. • Hands-on experience in lithium-ion cell manufacturing processes and product qualification • Familiarity with battery-specific metrology: coating weight, electrode thickness and density, porosity, tab alignment, and electrolyte fill weight measurement and control • Strong command of quality and problem-solving tools: DOE, RCCA/8D, SPC, GR&R/MSA, PFMEA, control plans, and capability analysis (Cpk/Ppk) • Knowledge of reliability methods relevant to batteries: Weibull analysis, HALT/HASS, accelerated life testing, and electrochemical failure mode characterization • Familiarity with GD&T, tolerance stack-up analysis, and metrology best practices in a precision manufacturing context • Experience managing CM/OEM quality relationships in Asia; ability to navigate cultural and organizational dynamics effectively • Track record of developing manufacturing process documentation that captures process rationale, critical control points, failure modes and equipment constraints. • Working knowledge of battery safety standards and certification pathways (IEC, UL, GB/T, KC, PSE) • Strong cross-functional communication skills; comfortable presenting technical findings to engineering and executive audiences
