Process Engineer Mixing & Coating – Battery Cell Development Center

• Process Development – Mixing & Slurry Preparation – You will help develop the process parameters, operating windows, and work instructions for slurry mixing (cathode and/or anode)
• Optimize mixing sequences, order of addition, shear rates, temperature, and vacuum/de‑aeration conditions
• Characterize slurry rheology and stability to establish acceptance criteria and checks
• Partner with product engineers and suppliers to qualify new active materials, binders, solvents, and conductive additives
• Process Development – Coating & Drying – You will help develop process parameters for roll‑to‑roll coating (e.g., slot‑die, comma bar) and drying for battery cell electrodes
• Tune key settings (web speed, gap, pump settings, tension, oven zones, air flows) to meet coating thickness, uniformity, and defect targets
• Develop and maintain procedures for set‑up, startup, changeovers, and shut‑down to ensure safe, stable operation
• Interface with calendaring and downstream steps to ensure coating output supports density, porosity, and cell performance targets
• Scale‑Up, Trials & Continuous Improvement - Plan and execute DOEs and structured experiments to expand process windows and improve yield, scrap, and throughput
• Partner with quality to analyze process and quality data and identify root causes of defects (e.g., streaks, agglomerates, edge defects, pinholes, delamination) and implement robust corrective actions
• Support equipment commissioning, debug, and SAT/FAT for new mixing and coating assets or upgrades
• Capture lessons learned and standardized best practices for reuse across campaigns and future lines
• Documentation – You will help to develop and maintain standard work, SOPs, control plans, and reaction plans for mixing and coating operations
• Work with quality to define CTQs/CTPs, sampling plans, and acceptance criteria for slurry, coated web, and in‑process checkpoints
• Maintain clear documentation of trials, parameter changes, risk assessments, and process changes
• Ensure compliance with GM safety standards, EHS requirements, and lean‑room/solvent‑handling procedures
• Cross‑Functional Collaboration - Work closely with operations/technicians to train and coach process intent, set‑up, troubleshooting, and best practices
• Partner with maintenance and controls/automation team members to improve uptime, diagnostics, and error‑proofing
• Collaborate with cell design, formation, and test teams to link electrode process conditions to cell performance and durability
• Communicate technical learnings and recommendations clearly to both technical and non‑technical stakeholders

• Bachelor's degree in chemical engineering, Materials Science, Mechanical Engineering, or related engineering field
• 3+ years of experience in process engineering, manufacturing engineering, or similar role in: Li‑ion battery manufacturing, or Coating, inks, films, or related web‑based processes, or Other wet‑chemistry / mixing‑intensive manufacturing
• Hands‑on experience with mixing processes (slurry, inks, coatings, or adhesives) and basic rheology concepts
• Hands‑on experience with coating or web handling processes (slot‑die, comma bar, gravure, or similar)
• Demonstrated ability to design and run DOEs, analyze data, and solve complex process problems with a structured approach
• Strong communication skills and ability to work cross‑functionally with operations, maintenance, quality, and suppliers
• Willingness to work in an onsite, pilot manufacturing environment with time spent on the production floor

• Direct experience in Li‑ion electrode manufacturing (slurry mixing, coating, drying, calendaring)
• Experience with roll‑to‑roll coating equipment and web handling (tension control, edge guiding, defect detection)
• Familiarity with battery materials (cathode/anode active materials, binders, solvents, conductive additives) and their impact on processability and performance
• Experience in a development, or ramp‑up environment (frequent changeovers, trials, and non‑steady‑state operation)
• Working knowledge of SPC, DOE, and basic statistics applied to manufacturing processes
• Experience using manufacturing data systems (historian, MES, quality databases) for troubleshooting and continuous improvement
• Demonstrated commitment to safety, including solvent handling, powder handling, and clean‑room or dry‑room operations
