Job description

Our client is a Singapore-based sustainable battery technology startup building safer, greener and more circular energy storage for consumer electronics, logistics and large-scale applications. Its R&D team is expanding into solid- and semi-solid-state battery technologies to speed up commercialisation.

What You’ll Do

• Research and develop solid-/semi-solid-state and next-generation battery chemistries
• Design and synthesise new electrode, electrolyte and separator materials
• Assemble and test coin, pouch, cylindrical and custom cell formats
• Run electrochemical characterisation (CV, EIS, GCD, cycle life, rate performance) and study degradation and interfacial behaviour
• Optimise cell design parameters (electrode loading, N/P ratio, electrolyte/cathode ratio) and benchmark against commercial Li-ion
• Scale lab results into manufacturable processes and prototypes
• Contribute to patents, and present prototypes at conferences and industry events
• Uphold lab safety and compliance with relevant battery standards (ISO, UL, EU)

Must-Have Requirements (Non-Negotiable)

• PhD in Materials Science, Electrochemistry, Chemical Engineering or a related field
• Hands-on experience with Li-ion batteries
• Experience with solid or semi-solid electrolytes for Li-ion batteries
• Industrial experience in battery R&D, development or manufacturing (not only academic)

Core Key Skills

• Electrochemical cell assembly and testing
• Glovebox handling and wet-chemical synthesis
• Analytical techniques such as XRD, SEM/TEM, XPS, Raman and ICP-MS
• Strong grounding in electrochemical theory and kinetics
• Published battery research
• Clear communication and comfort working in a multidisciplinary team

Nice to Have

• Computational modelling or machine learning for materials discovery
• Experience scaling lab processes to pilot or production
• Patent filing experience
