We’re looking for a UAV Mechanical Design Engineer with a keen interest in developing and prototyping special-purpose Unmanned Aerial Systems (UAS) to join our small but fast-paced Research Engineering 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 UAS platforms. 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.”

• Assist in the ongoing development of special-purpose Unmanned Aerial Systems for the maritime domain.
• Rapid prototyping of UAS systems and subsystems, from concept to fully functioning prototypes.
• Assist with the mechanical, electrical, and system-level design of UAS platforms.
• Undertake a combination of office-based design work and hands‑on practical workshop tasks to support prototype builds, including mechanical and electrical assembly.
• Assist with sensor integration.
• Support the execution of test and validation activities both on‑site (e.g. test rigs) and when required; off‑site during system/flight 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.
• Assist with other tasks (outside of UAS) as required by the business.

• Bachelor’s or higher degree in an associated engineering discipline.
• Engineering creativity, a desire not just do but excel and push boundaries.
• Demonstrable design/build experience with unmanned aerial systems (fixed-wing and/or multirotor).

• Understanding of flight dynamics across platform designs (fixed/rotary wing).
• Understanding of material properties and selection criteria for a specific task.
• Understanding of manufacturing processes and design for manufcture
• Understanding of configuration control process and importance of implementation.
• Understanding of GD&T drawing methodology.
• Flexibility and adaptability.
