We are looking for a Mechanical Design Engineer to work on developing our large fixed- wing UAV systems, operating in real logistics and defence missions, where reliability, efficiency and practical engineering matter.

In this role you will design aircraft structures, mechanisms and mechanical subsystems, translating system requirements into lightweight, manufacturable designs. You will support the full development lifecycle — from concept design through prototyping, testing and production — working closely with multidisciplinary teams across engineering, manufacturing and flight operations. We’re looking for engineers who enjoy solving real engineering problems and want to see their designs built, tested and flown. The role suits someone who is comfortable working across design, prototyping and manufacturing, and who thrives in a collaborative development environment.

Responsibilities/Tasks

Develop 3D CAD models and 2D manufacturing drawings for UAV components and assemblies including structural elements, payload integration solutions and mechanical subsystems.
Produce manufacturing documentation, BOMs and technical specifications for in-house and external manufacturing.
Support prototype builds, ground testing and flight testing, troubleshooting mechanical issues and implementing improvements.
Support full lifecycle of designs, change management, manufacturing at scale and operations.
Contribute to design reviews, clearly communicating engineering decisions, trade-offs and risks.

Other responsibilities as agreed with your Manger
Conduct yourself in a professional manner at all times in accordance with the company expected behaviours and values
Work in accordance with company policies, procedures and guidelines

Act always in a safe manner and in support of our Health and safety agenda

Skills/Knowledge

Degree in Mechanical Engineering, Aerospace Engineering, or related discipline.
3+ years mechanical design experience in aerospace, UAV, defence or relevant sector (vehicles, automotive/motorsport).
Strong CAD skills, strong preference for SolidWorks and SolidWorks PDM.
Experience with structural analysis / FEA of components and assemblies is desirable but not necessary.
Experience designing lightweight structural assemblies, mechanical systems, and payload integration activities.
Experience producing engineering drawings, BOMs and manufacturing documentation.
Knowledge of manufacturing processes such as machining, sheet metal fabrication, bonded or riveted assemblies (composites experience is advantageous).
Right to work within the UK
Ability to travel abroad to EU and non-EU territories
Vetting and security clearance (as required by role, location or client)
