Radical Builders is an applied R&D organisation developing hardware for civil and defence applications. We bring engineers, inventors and end-users together to turn an operational challenge into a prototype and test it in practice.

We bring together teams of curious students, experienced inventors, engineers and industry partners. Each team is shaped around the challenge, combining fresh thinking with the experience to build and test real hardware.

We focus on ambitious problems where building and testing hardware can prove a new approach. Our current work spans maritime autonomy, aerial systems and subsea technology. We start with the needs of the people who will use it and test what works in practice.

A prototype helps establish what works and what needs further development. From there, we can continue with industry partners or help a promising concept grow into a dedicated venture. Radical remains the R&D home for new ideas and the next technical challenge.

Bring an operational challenge, contribute your expertise or join a project. We welcome students, experienced builders, inventors and potential partners. Get in touch or explore our careers page; the role, timing and terms depend on the project and are agreed together.
