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.
As a Battery Module Engineer, you will play a key role in scaling this step‑change technology, supporting the integration of cells into high-performance systems and enabling deployment into real-world applications.
You will work within the Scale‑up and Deployment team, collaborating closely across engineering, product, 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.
Key responsibilities
* Accountable for the scale‑up of laboratory cells into large‑format cells, including design, assembly, and validation activities
* Responsible for designing compression system concepts, with characterisation across both cell and module levels
* Responsible for defining and implementing thermal and gas management strategies at cell and module scale
* Responsible for establishing and continuously improving quality control approaches for functional and packaging components at cell level
* Responsible for designing and integrating cell‑to‑module electrical interfaces in collaboration with Electronics Team
* Interact closely with the Cell Mechanical Engineer to align on scaled cell design, prototyping methodologies, validation, and module packaging strategies
* Responsible for creating and maintaining high-quality CAD models and engineering drawings to support packaging, prototyping, and manufacturing
* Responsible for change control activities within the function, including maintaining accurate Bills of Materials, Engineering Change Notices, and full design traceability
* Champion safe working practices, ensuring compliance with internal safety standards, training, and engineering best practices
Are you the ideal candidate?
You will have/be:
* Degree in Mechanical Engineering or related discipline; alternatively, have demonstrable experience in a similar role from a related field of expertise
* Demonstrable hands‑on experience scaling products from prototype through to production in a commercial environment (battery/energy storage experience advantageous)
* Proven track record of designing practical, manufacturable, and cost‑efficient solutions, with strong Design for Manufacturing (DFM) and Design for Assembly (DFA) capabilities across metal and plastic processes
* Good working knowledge of CAD and engineering drawing, including tolerance analysis and design release practices
* Track record of delivering complex engineering projects to challenging timelines in fast‑paced environments
* Ability to navigate ambiguity and drive practical solutions in evolving technical landscapes
* Clear and structured communicator, able to document and transfer technical knowledge effectively
* Collaborative and proactive mindset, with the ability to operate both independently and across functions
