Qualifications

• Master’s degree in chemistry, chemical engineering, materials science, electrochemistry, or related discipline.
• Seven or more years of experience in lithium-ion battery cell development, characterization, testing, or validation.
• Demonstrated experience completing at least one full lithium-ion battery cell product-development cycle, from concept to mass production.
• Hands-on experience designing, executing, and interpreting lithium-ion cell performance, life, and degradation tests.
• Experience with GITT, EIS, CV, and PITT techniques.

Responsibilities

• Serve as the lead technical interface for U.S. OEM customers on battery cell design, development, validation, and industrialization.
• Provide technical leadership in customer discussions covering cell architecture, materials, electrochemical performance, safety, lifetime, fast charging, and manufacturability.
• Represent Gotion’s cell design and manufacturing capabilities, technology roadmap, product portfolio, and development maturity to OEM customers.
• Translate customer vehicle-, pack-, and system-level requirements into cell-level design requirements, targets, and engineering trade-offs.
• Build a deep understanding of customer applications, duty cycles, operating environments, and pack constraints to guide optimal cell and pack integration.
• Develop cell design solutions that balance energy density, power capability, safety, durability, cost, and manufacturing feasibility.
• Lead technical alignment with customers on cell requirements, design specifications, interface definitions, validation plans, and acceptance criteria.
• Lead cell design reviews, technical workshops, and engineering discussions with customers and internal teams from RFI/RFQ through development, launch, and mass production.
• Develop test methods and validation strategies to evaluate cell-level and cell-in-pack performance, safety, reliability, and durability.
• Analyze and interpret cell test data to assess design performance, identify technical risks, and recommend design improvements.
• Lead root-cause investigations and corrective actions for cell design, performance, safety, and manufacturing issues; clearly communicate findings and recommendations to customers.
• Provide technical leadership throughout the complete cell development lifecycle, including concept development, design optimization, design verification, manufacturing scale-up, launch, and post-launch improvement.
• Collaborate with cross functional teams to develop DFMEAs and PFMEAs, identify critical design and process characteristics, and coordinate FMEA reviews with customers.
• Support customer-facing quality and industrialization activities, including APQP, PPAP, design reviews, process reviews, and technical audits.
