What are the responsibilities and job description for the Battery Cell Process Engineer (Pilot Line / Prototyping) position at Info Way Solutions?
Position Overview
We are seeking a detail-oriented Battery Cell Process Engineer to support the fabrication, assembly, and prototyping of next-generation high-energy battery technologies. In this role, you will work closely with senior process and cell design engineers to operate and maintain lab-scale pilot line equipment, fabricate pouch cells, optimize assembly parameters, and ensure high manufacturing yield, quality, and repeatability across experimental builds.
Key Responsibilities & Deliverables
End-to-End Pouch Cell Fabrication: Support complete pilot-line cell assembly, including slurry mixing, electrode coating (slot-die/doctor-blade), calendering, slitting/die-cutting, precision stacking, tab welding, pouch sealing, electrolyte filling, and formation.
Equipment Operation & Maintenance: Operate, calibrate, and maintain dry room systems, glove boxes, pilot-line tooling, and assembly equipment to preserve baseline process capabilities.
Process Optimization & DOEs: Execute Design of Experiments (DOEs) to identify Critical Process Parameters (CPPs) and optimize cell yield, thickness uniformity, loading density, and energy density.
Quality Assurance & Defect Analysis: Perform in-line quality inspections (e.g., seal integrity, alignment checks), log build metrics into tracking databases, and troubleshoot fabrication defects (e.g., coating pinholes, delamination, stacking misalignment, poor wetting).
Documentation & Safety Standards: Author and update Standard Operating Procedures (SOPs), assembly traveler logs, and safety protocols for new battery chemistries and form factors, ensuring strict adherence to hazardous materials handling.
Minimum Qualifications
Education: Bachelor’s degree in Materials Science, Chemical Engineering, Mechanical Engineering, Electrical Engineering, or equivalent practical experience.
Pilot Line Experience: 1 years of practical, hands-on experience operating lab-scale pilot line equipment for pouch cell fabrication.
Cleanroom / Dry Room Skills: Direct laboratory experience handling battery active materials, chemical reagents, and precision mechanical assembly tools.
Process Knowledge: Practical understanding or coursework in lithium-ion manufacturing workflows (slurry preparation, coating, calendering, stacking, electrolyte filling).
Operational Discipline: Strong documentation habits, acute attention to detail with delicate components, and compliance with lab safety protocols.
Preferred Qualifications
Specialized experience operating automated tab welding (ultrasonic/laser) and vacuum electrolyte filling/sealing machinery.
Familiarity with Statistical Process Control (SPC), yield analysis, and data analysis tools (Python, MATLAB, JMP, or advanced Excel).
Functional understanding of how upstream slurry and coating variations impact downstream electrochemical performance and cell degradation.
