SuperDielectrics (SD) is pioneering a breakthrough battery technology designed for the high-power markets of the future, supporting the global shift to electrification. Our water-based batteries deliver market-leading performance through a novel polymer separator, combined with zinc halide electroactive species and carbon-based porous electrodes.
To accelerate commercialisation, SD operates a fully integrated product development model - from advanced materials through to cells, modules and packs - underpinned by in-house battery management systems.
Our technology is built around the polymer separator and, as the Polymer Application Scientist, you will lead the design, synthesis and characterisation of separator materials that underpin the performance of our next-generation battery products. Working from customer and application requirements, you will develop innovative polymer technologies that improve battery performance, reliability and lifetime across targeted markets. As the technical owner of separator materials and their application performance, you will translate polymer science into commercially viable products, ensuring new materials meet customer expectations while working in close partnership with the Development Scale-up Engineer, who leads the industrialisation and manufacturing scale-up of those technologies.
You will work within the Product team, collaborating closely across engineering, application testing and commercial functions to translate innovation into deliverable products.
This is a rare opportunity to join a high-growth, entrepreneurial business at a pivotal stage. While experience in battery technologies is advantageous, we actively welcome candidates from adjacent fields - bringing fresh perspectives to complex engineering challenges. In return, we offer a world-class environment to develop deep expertise in next-generation energy storage
