• Drive the development of new materials and process platforms in alignment with the company’s technical roadmap.
• Conduct and lead failure analysis (FA) and technical troubleshooting related to materials and manufacturing processes.
• Provide technical documentation and cross-functional support to R&D and manufacturing teams.

Requirements

• Education: Master’s degree or higher in Materials Science, Chemical Engineering, or a related discipline.
• Experience: Minimum 3 years in material or product development, with solid experience in lithium-ion battery materials.
• Proven ability to independently lead material or product development projects.
• Strong analytical and problem-solving skills, including data analysis and failure analysis experience.
• Excellent communication skills in English, both written and verbal.
• Experience in customer-facing technical discussions; background in EV battery development is highly preferred.
