We’re looking for a Senior Prototyping Engineer to join our fast-paced R&D team. The role involves a mixture of conceptual and detailed design across multiple engineering disciplines, as well as hands-on workshop tasks and the assembly of prototype objects. The ideal candidate is someone who takes a pragmatic approach to solving engineering challenges using an iterative development process, with the mindset of "fail fast, learn faster."

We are particularly interested in candidates with a strong background in embedded systems including PCB development, electrical and RF. The overview is deliberately vague with the candidate needing to be excited to support multiple domains in support of our Diver Delivery, USV and UAV systems, and as such, people with experience in any of the above will be considered.

• With a broad scope and limited guidance, take a leading role in rapid prototyping of systems, from concept to fully functioning prototypes.
• Support the smooth transitioning of successful prototypes to Engineering.
• Undertake a combination of office-based design work and hands-on practical workshop tasks to support prototype builds, including mechanical and electrical assembly.
• Assist and mentor others in a collaborative environment to achieve our common goals.
• Support the execution of test and validation activities both on-site (e.g. test rigs) and off-site during system testing at external test locations.
• Liaise with other business units (e.g. trials team, commercial, procurement, manufacturing, etc.).
• Occasional travel abroad.
• Work with external partners on component procurement and legislative/compliance requirements.
