The Opportunity:

Factorial Energy is seeking a Senior / Staff Formation Equipment Engineer to join our Cheonan, South Korea site. This role owns the full-cycle development, commissioning, customization, optimization, and mass production scaling of automatic formation equipment for our Silicon Power Cell pouch cell line. The ideal candidate will lead new formation equipment R&D, prototype debugging, pilot verification, and mass production iteration; deliver equipment technical upgrades and OEE & yield improvements; and build a standardized equipment management system.  

 

In this role, you will:

• Lead full-lifecycle development, commissioning, and mass-production validation of formation equipment, iterate process parameters, and complete equipment adaptation for new product launch.
• Conduct equipment review, FAT/SAT acceptance and IQ/OQ/PQ qualification, and unify precision control standards for formation equipment.
• Upgrade and retrofit mass-production formation machines to improve OEE, yield and line capacity, and reduce production costs.
• Optimize formation charge-discharge process parameters to stabilize production, improve cell consistency and support rapid multi-spec product changeover. Collaborate with cross-functional teams and external vendors to promote new line startup, equipment development, and technical renovation.
• Optimize formation power logic to adapt silicon anode expansion characteristics.
• Lead equipment technical transfer from lab/pilot EVT/DVT/PVT to mass production, identify production bottlenecks and drive sustained yield improvement.
• Adopt 8D, DOE, SPC, and root-cause analysis to resolve formation defects, drive cross-functional troubleshooting, and close CAPA for recurrent failures.
• Build a complete standardized equipment management system, compile SOPs, maintenance schedules, calibration specifications, PFMEA, control plans, and an equipment failure database for formation stations. 

 

We are looking for people who:

• Bachelor’s degree or above in mechanical, mechatronics, electrical automation, materials, chemical engineering, or related fields.
• 3+ years of experience in pouch cell formation equipment development, retrofit, and production ramp-up.
• 2+ years of professional experience in formation machine structure and control logic; skilled in formation charging/discharging curve and pressure parameter tuning.
• Capable of mechanical/electrical drawing reading and CAD/SolidWorks fixture design; familiar with servo control and power closed-loop systems.
• Proficient in DOE, PFMEA, Control Plan, 8D and root cause analysis; independent in equipment troubleshooting and technical optimization.
• Experienced in pouch cell formation line NPI and mass production ramp-up projects.
• Equipped with cross-functional coordination, project management, and vendor communication abilities; competent in on-site troubleshooting and English technical documentation.
