Job summary

We are seeking a highly skilled and motivated materials scientist to join our team focused on advancing lithium-ion battery technologies. The ideal candidate will lead the development, testing, and optimisation of novel materials used in cell components (electrodes, electrolytes, separators, etc.). This role will also involve supervising a multidisciplinary team of technicians and engineers, overseeing cell testing protocols, and conducting in-depth data analysis to support performance improvements and innovation. The candidate will play a critical role in shaping our materials strategy, enhancing product performance, and accelerating R&D timelines.

Key Responsibilities

Lead the development, selection, and optimisation of materials for lithium-ion battery components, including active materials, binders, electrolytes, and conductive additives. Design and execute experiments for material characterisation, performance benchmarking, and process compatibility. Oversee the day-to-day activities of junior engineers and junior scientists, providing technical direction and ensuring adherence to safety and quality protocols. Develop and implement protocols for cell fabrication, testing, and validation, including coin, pouch, or cylindrical cells. Analyse electrochemical performance data to draw insights and inform material and process improvements. Collaborate with cross-functional teams, including cell design, manufacturing, and quality assurance, to align material development with product goals. Prepare technical reports, presentations, and documentation for internal stakeholders and external partners or funding agencies. Stay updated with the latest advancements in battery materials science and contribute to strategic R&D planning.
