Electrode Process Engineer

Responsibilities

• Lead development and optimization of anode and cathode electrode processes for Si-based power cells, including slurry mixing, slot-die coating, drying, calendaring, and slitting
• Define and maintain process windows for slurry rheology, coating weight, thickness uniformity, calendaring density, and adhesion strength
• Establish and maintain SOPs, PFMEA, and Control Plans for all electrode process steps
• Develop electrode formulation strategies to accommodate silicon anode expansion/contraction behavior
• Design and optimize high-solid slurry mixing sequences, dispersion conditions, and deaeration protocols
• Control slurry rheology to minimize defects and achieve thickness uniformity
• Optimize slot-die coating parameters including coating speed, gap, pump rate, and drying profile
• Develop process-structure-performance correlations linking slurry properties to electrode quality
• Define calendaring conditions to achieve target porosity and density
• Optimize slitting conditions to minimize burr generation and edge defects
• Lead electrode process transfer from lab/pilot scale to new line
• Participate in NPI stage-gate reviews (EVT/DVT/PVT/MP)
• Support FAT/SAT and equipment qualification (IQ/OQ/PQ)
• Apply DOE, SPC, and FMEA methodologies to drive yield improvement
• Partner with QA/QE to define incoming material inspection criteria
• Work with R&D, cell design, and production teams to align process requirements with performance targets

Requirements

• 3+ years of hands-on experience in lithium-ion electrode process development or manufacturing
• Direct experience with anode or cathode wet electrode processes (mixing, coating, calendering)
• Experience leading or contributing to at least one full NPI or mass production ramp-up project
• Deep understanding of slurry rheology, slot-die coating physics, and drying/calendering fundamentals
• Proficiency in DOE, SPC, and data analysis tools (Python, MATLAB, JMP, or Minitab)
• Experience with material characterization methods (SEM, adhesion testing, viscosity/rheology measurement)
• Bachelor's degree or higher in Chemical Engineering, Materials Science, Mechanical Engineering, or related field

Preferred Qualifications

• Experience with silicon anode electrode processes or high-solid slurry systems
• Familiarity with process qualification frameworks (PFMEA, Control Plan, SOP)
• Advanced degree in a related engineering field
• Experience with silicon anode (Si/C composite) electrode development
• CFD or FEM-based coating/mixing process modeling experience
• Familiarity with IATF 16949 or automotive quality frameworks
