Formation Process Engineer

Responsibilities

• Lead development and optimization of formation protocols for Si-based power cells
• Design and validate formation recipes to maximize ICE and SEI film uniformity
• Establish capacity grading specifications including capacity, DCIR, and self-discharge rate
• Develop product-specific formation programs optimized for high-rate power cell requirements
• Collaborate with R&D and electrode teams to correlate formation conditions with cell stability
• Identify root causes of formation and grading anomalies and implement CAPA actions
• Apply SPC, DOE, and FMEA methodologies to improve process capability
• Optimize formation line takt time, OEE, and reduce energy consumption
• Drive process transfers from lab bench to pilot line and mass production
• Lead FAT/SAT acceptance testing and establish OQ/PQ qualification protocols

Requirements

• 3+ years of hands-on experience in lithium-ion battery formation and grading processes
• Bachelor's degree or higher in Chemical Engineering, Materials Science, Electrochemistry, or related field
• Experience with major formation cycler platforms (Neware, Landt, Arbin, Basytec)
• Proficiency in electrochemical testing (EIS, DCIR, self-discharge) and data analysis tools (JMP, Minitab, Python, or Excel)
• Experience with MES/ERP data extraction and visualization

Preferred Qualifications

• Experience with silicon anode or high-energy-density cell formation
• Experience leading NPI or mass production ramp-up projects
• Deep understanding of SEI formation, gas evolution, and electrolyte decomposition
• Familiarity with consumer battery safety standards (IEC 62133, UL 1642, UN 38.3)
