Electrode Process Engineer
On-site · Cheonan, Chungcheongnam-do, South Korea
Job Summary
Electrode Process Engineer to lead development, optimization, and scale-up of anode and cathode electrode manufacturing processes for Silicon Power Cell lines, spanning slurry mixing, slot-die coating, drying, calendaring, and slitting. Drive process windows for slurry rheology, coating weight, thickness uniformity, calendaring density, and adhesion; establish SOPs, PFMEA, and Control Plans; develop electrode formulation strategies to accommodate silicon expansion/contraction; design high-solid slurry mixing sequences, dispersion, and deaeration; control slurry rheology to minimize defects and ensure coating stability; optimize coating and calendaring parameters; develop process-structure-performance correlations; transfer electrode processes from lab/pilot to mass production; participate in NPI stage-gate reviews and equipment qualification; apply DOE, SPC, and quality tools; collaborate with R&D, cell design, equipment, and production teams to align process requirements with cell performance targets.
Required Qualifications
- Bachelor's degree or higher in Chemical Engineering, Materials Science, Mechanical Engineering, or related field (advanced degree preferred)
- 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)
- Led or substantially contributed to at least one full NPI or mass production ramp-up project
- Deep understanding of slurry rheology, slot-die coating physics, and drying/calendering process fundamentals
- Experience with silicon anode electrode processes or high-solid slurry systems preferred
- Familiar with PFMEA, Control Plan, SOP
- Proficient in DOE, SPC, and data analysis tools (Python, MATLAB, JMP, or Minitab)
- Experience with material characterization methods (SEM, adhesion testing, viscosity/rheology measurement)
- Experience with silicon anode (Si/C composite) electrode development or high-Si loading process challenges (preferred)
- CFD or FEM-based coating/mixing process modeling experience (preferred)
- Familiar with IATF 16949 or automotive quality frameworks (preferred)
- Work Location: Cheonan, South Korea
