Battery Process Engineer

The Battery Cell Process Engineer (Pilot Line / Prototyping) will be supporting the
fabrication and prototyping of next-generation battery technology for high-energy
applications. The vendor will support senior process and cell design engineers by
operating and maintaining lab-scale pilot line equipment, building pouch cells
systematically, optimizing cell assembly parameters, and ensuring high manufacturing
quality and repeatability across experimental builds.
Services and Deliverables
● 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 Standard Operating Procedures (SOPs), assembly traveler logs, and
safety protocols for new chemistries and form factors.
Minimum Qualifications (Reference only)
● 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.
Preferred Qualifications (Reference only)
● Working knowledge of pouch cell fabrication equipment, including tab welding,
and electrolyte filling/sealing equipment.
● Familiarity with statistical process control (SPC), yield analysis, and basic data
analysis tools (e.g., Python, MATLAB, JMP, Excel).
● Understanding of how upstream process variations impact downstream cell
quality and electrochemical performance.
