Battery Process Engineer

Infowaysolutions; Mountain View (CA); On-site; USD 90,000 - 150,000; Full time

Job summary

Infowaysolutions in Mountain View, CA is seeking a Battery Cell Process Engineer to support lab-scale pouch cell fabrication and prototyping for next‑generation energy storage.

You will operate pilot line equipment, perform DOE studies to optimize CPPs, and document SOPs while maintaining safety and quality across experimental builds. Experience with slurry coating, calendering, stacking, electrolyte filling, and formation is preferred; hands-on lab experience essential.

Qualifications

• Bachelor's degree in Materials Science, Chemical Engineering, Mechanical Engineering, Electrical Engineering, or equivalent practical experience.
• 1+ years of practical experience operating lab-scale pilot line equipment for pouch cell fabrication.
• Hands-on laboratory or cleanroom/dry room experience handling battery materials, chemicals, and mechanical assembly tools.
• Direct experience or coursework involving lithium-ion cell manufacturing processes (e.g., slurry preparation, slot-die/doctor-blade coating, calendering, stacking, electrolyte filling, etc.)
• Strong documentation skills, attention to detail in handling delicate pouch cell components, and adherence to lab safety/hazardous materials handling protocols.

Responsibilities

• Support end-to-end lab-scale pouch cell fabrication, including slurry mixing, electrode coating, calendering, slitting/die cutting, precision stacking, tab welding, pouch sealing, electrolyte filling, and formation.
• Operate, calibrate, and maintain pilot line equipment, tooling, dry rooms, and glove boxes to maintain baseline process capability.
• Execute Design of Experiments (DOEs) for process optimization, identifying critical process parameters (CPPs) to improve cell yield, uniformity, and energy density.
• Perform in-line quality inspections (e.g., thickness uniformity, loading density, alignment checks, seal integrity) and log fabrication metrics into tracking databases.
• Troubleshoot fabrication defects (e.g., coating pinholes, delamination, stacking misalignment, poor wetting) and work with senior engineers to implement corrective actions.
• Document SOPs, assembly traveler logs, and safety protocols for new chemistries and form factors.
