SuperDielectrics (SD) - Polymer Application Scientist
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.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.

Key Responsibilities
- Accountable for the design, synthesis and optimisation of current and next-generation polymer separator materials that deliver differentiated battery performance for customer applications.
- Accountable for translating customer, application and product requirements into scalable polymer chemistries suitable for commercial manufacture.
- Responsible for driving innovation in separator composition, structure and functionality to improve battery performance, reliability, durability and customer value.
- Responsible for developing and continuously improving polymer and separator characterisation methodologies that enable prediction of product performance, quality and long-term reliability.
- Work with electrochemists, materials scientists, application engineers and product teams to establish the relationships between polymer chemistry, separator structure, electrochemical behaviour and end-use battery performance.
- Investigate polymer degradation mechanisms during battery cycling to improve product lifetime, robustness and application-specific performance.
- Work closely with the Development Scale-up Engineer to ensure new separator materials can be successfully transferred into robust manufacturing processes, providing materials leadership while supporting process industrialisation.
- Support product development by defining critical material properties, application-relevant performance metrics and technical specifications for separator technologies throughout the product lifecycle.
- Coordinate cross-functional activities to ensure separator development aligns with customer requirements, product roadmaps, validation activities and future technology platforms.
- Interact closely with the Head of Product to align polymer innovation with customer needs, commercial priorities and the wider technology roadmap.
- Champion safety, effective training and adherence to SD safety rules and best practices.
