Senior Customer Quality Engineer

The starting base pay for this role is between $156,000 and $197,000 at the time of posting.

• 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 level
• 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
