Job Description
Cheonan, South Korea
Key Responsibilities
- Factorial Energy is seeking a Senior / Staff Cell Finishing Equipment Engineer to join our Cheonan, South Korea site. The ideal candidate owns the full-cycle development, commissioning, customization, optimization, and mass production scaling of automatic final sealing, edge folding, OCV testing, and X-ray inspection equipment for our Silicon Power Cell pouch cell line. This person will lead new post-process equipment R&D, prototype debugging, pilot verification, and mass production iteration; deliver equipment technical upgrades, OEE & yield improvements; and build a standardized equipment management system.
- Lead full-lifecycle development, commissioning and mass-production validation of automatic final sealing, folding, OCV and X-ray inspection equipment, iterate core process parameters and complete equipment adaptation for new product launch.
- Conduct equipment review, FAT/SAT acceptance and IQ/OQ/PQ qualification, and unify precision and quality control standards for post-process assembly and inspection procedures.
- Upgrade and retrofit mass-production final sealing, folding and inspection equipment to improve OEE, production yield and line capacity, and reduce manufacturing costs.
- Optimize sealing fixtures, folding structures, testing probes and machine vision parameters to stabilize production, eliminate poor sealing, folding offset, OCV testing deviation and X-ray detection errors, and support rapid multi-spec pouch cell changeover.
- Build complete standardized equipment management systems for post-process stations, including SOPs, maintenance schedules, calibration specifications, PFMEA, control plans, and equipment failure databases.
- Collaborate with cross-functional teams (R&D, Process, Quality, Manufacturing, Maintenance) and external vendors to advance new line startup, equipment development and technical renovation projects.
- Optimize post-process temperature & pressure closed-loop logic, servo positioning, electrical signal acquisition, and X-ray imaging algorithm to adapt silicon anode cell characteristics and eliminate assembly & inspection defects.
- Lead equipment technical transfer from lab/pilot EVT/DVT/PVT to mass production, identify equipment bottlenecks and drive sustained yield improvement.
- Adopt 8D, DOE, SPC, and root-cause analysis to resolve typical post-process abnormalities, drive cross-functional troubleshooting, and close CAPA for recurrent equipment failures.
Requirements
- 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.
