Senior Staff Quality Engineer, Battery Manufacturing

About UsWe are Sila, a next-generation battery materials company. Our mission is to power the world’s transition to clean energy. To create this future, our team is building a better lithium-ion battery from the inside out today. We engineer and manufacture ground-breaking battery materials that significantly increase the energy density of batteries, while reducing their size and weight. The result? Smaller more powerful batteries that can unlock innovation in consumer devices and accelerate the mass adoption of electric cars to eliminate our dependence on fossil fuels. We're tackling one of the biggest challenges of our time every day, and together we're redefining what's possible. Are you ready to be a part of a team committed to changing the world? Who You AreIn 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.Responsibilities and Duties  Manage IQC, IPQC, OQC, and ORT across battery cell production linesDrive quality readiness at the Contract Manufacturer (CM) for development builds (EVT/DVT/PVT) and mass production ramp, including establishing inspection and hold/release protocolsLead root cause and corrective action (RCCA) investigations for quality escapes; present findings and closure plans to internal and CM leadership as requiredCollaborate 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 implementationConduct periodic factory quality reviews covering yield, scrap, defect Pareto, and process capability trendsPrepare OK-to-Ship and lot dispositioning documentation for new product launch and ongoing mass productionDevelop and maintain risk assessments (PFMEA) for battery manufacturing processes; implement control plans and reaction plans for identified risk itemsSupport 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 specificationDevelop and execute module and cell reliability test plans (cycle life, calendar aging, thermal abuse, mechanical) during NPI and MP, in coordination with internal engineering teamsEnsure 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 leve30–40% international travel to CM sites in Asia requiredKnowledge and Skill Requirements 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 qualificationFamiliarity with battery-specific metrology: coating weight, electrode thickness and density, porosity, tab alignment, and electrolyte fill weight measurement and controlStrong 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 characterizationFamiliarity with GD&T, tolerance stack-up analysis, and metrology best practices in a precision manufacturing contextExperience managing CM/OEM quality relationships in Asia; ability to navigate cultural and organizational dynamics effectivelyTrack 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 audiencesPhysical Demands and Working ConditionsWear personal protective equipment including, but not limited to, a lab coat, gloves, safety glasses, and steel toe safety shoesMove items up to 50 lbs with the assistance of lift equipment and cartsMove long distances (such as from building to building) and be stationary for extended periods of timeOperate a computer and other office equipment, such as a laptop, copier/printer, etc in a fixed locationThe starting base pay for this role is between $156,000 and $197,000 at the time of posting.
