PERSON PROFILE

Key Accountabilities and Responsibilities

- Process Design & Optimization: Design, develop, and optimize the coating process for anode and cathode electrodes using slot-die and gravure coating techniques.
- Establish and fine-tune slurry viscosity, solid content, and rheological properties for optimal coatability and film uniformity.
- Define and control critical process parameters, including coating speed, gap settings, drying temperature profile, and web speed.
- Ongoing ownership of key process control points, using data and analysis to drive continuous improvement to product and process.
- Develop the manufacturing process, including the design, control strategy and risk mitigation activity for key areas of the end-to-end production process.
- Scale-up & Commissioning: Responsible for the scale-up mixing equipment to mass production levels.
- Support implementation plans and associated actions to ensure compliance with targets for OEE, yield, cycle time and product quality throughout the industrialization lifecycle
- Equipment & System Management: Select, install, and qualify coating equipment, including thickness gauges, drying ovens, and tensioning systems.
- Ensure proper roller alignment, web handling stability, and tension control to maintain consistent coating quality.
- Collaborate with vendors and internal teams on equipment calibration, maintenance, and upgrades.
- Defect Detection & Mitigation: Identify and resolve coating-related process issues such as non-uniform coating, coating delamination, edge defects, air bubbles, and surface irregularities.
- Monitor process KPIs and lead continuous improvement initiatives to enhance throughput, quality, and cost-efficiency.
- Quality & Documentation: Develop SOPs, process flow diagrams, PFMEAs, control plans, and other quality documentation.
- Work closely with the quality team to ensure coating process compliance with internal and external standards.
- Cross-functional Collaboration: Collaborate with teams across materials, cell design, quality assurance, automation, and maintenance to ensure smooth process integration and alignment with product goals.

Knowledge, Skills and Experience

Essential

- Understanding of slot-die, and gravure coating methods, with hands-on experience in adjusting gap settings, coating speed, and slurry viscosity to optimize uniformity.
- Ability to interpret data from thickness gauges, in-line vision inspection systems, and IR sensors to maintain coating consistency.
- Exposure to web handling principles, including tensioning systems, roller alignment, and defect mitigation (e.g., wrinkling, edge cracking).
- Identify and resolve process issues related to coating defects such as non-uniform coating, coating delamination, or irregularities in electrode surface quality.

Desired

- Strong understanding of the properties of materials used in lithium-ion battery electrodes, including the behaviour of slurries, binders, and additives during the coating process.
- Expertise in optimizing coating processes, including the ability to design experiments (DOE) to improve coating uniformity, efficiency, and quality.
- Working knowledge of safety standards related to chemical handling and powder processing (e.g., MSDS, ATEX, NFPA)
- Strong communication and cross-functional collaboration skills to work effectively with R&D, quality, and production teams
- Understanding of industry standards for lithium-ion cell manufacturing (e.g., ISO, IATF 16949)

Role Specific Qualifications/Certifications

- Bachelor’s or master’s degree in chemical engineering, Materials Science, Mechanical Engineering, or a related field
- 3–7 years of experience in a manufacturing environment, preferably in battery, chemical, or pharmaceutical industries.
