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

You will be:

• 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
