Senior / Staff Cell Finishing Equipment Engineer

The role

This person will own the full-cycle development, commissioning, and mass production scaling of automatic final sealing, edge folding, OCV testing, and X-ray inspection equipment for the Silicon Power Cell pouch cell line. They will lead equipment R&D, prototype debugging, and mass production iteration to improve OEE and yield.

What you will do

• Lead full-lifecycle development, commissioning and mass-production validation of automatic final sealing, folding, OCV and X-ray inspection equipment.
• Conduct equipment review, FAT/SAT acceptance and IQ/OQ/PQ qualification.
• Upgrade and retrofit mass-production equipment to improve OEE, production yield and line capacity.
• Optimize sealing fixtures, folding structures, testing probes and machine vision parameters.
• Build standardized equipment management systems including SOPs, maintenance schedules, and PFMEA.
• Collaborate with cross-functional teams and external vendors for line startup and technical renovation.
• Optimize post-process temperature and pressure closed-loop logic, servo positioning, and X-ray imaging algorithms.
• Lead equipment technical transfer from lab/pilot to mass production.
• Adopt 8D, DOE, SPC, and root-cause analysis to resolve post-process abnormalities.

Required qualifications

• Bachelor’s degree or above in mechanical, mechatronics, electrical automation, materials, chemical engineering, or related fields.
• 3+ years of experience in pouch cell final sealing, folding, OCV & X-ray equipment development, retrofit and production ramp-up.
• 2+ years of professional experience in post-process equipment structure and control logic.
• Skilled in sealing temperature/pressure tuning, folding precision control, electrical testing calibration, and X-ray inspection parameter optimization.
• Capable of mechanical/electrical drawing reading and CAD/SolidWorks fixture design.
• Familiar with servo motion, constant temperature-pressure control, precision testing and machine vision inspection systems.
• Proficient in DOE, PFMEA, Control Plan, 8D and root cause analysis.
• Independent in equipment troubleshooting and technical optimization.
• Experienced in pouch cell post-process line NPI and mass production ramp-up projects.
• Equipped with cross-functional coordination, project management, and overseas vendor communication abilities.
• Competent in on-site troubleshooting and English technical documentation.
• Proficient in English for technical document reading, global technical meetings, and technical report delivery.
