Senior Mechanical Engineer

As winner of the 2024 and 2023 Defence Innovator of the Year and finalist in 2025 and 2026, our values of integrity, innovation, professionalism and passion are at the for front of everything we do. Our vision is to be a world leader in defence innovation through developing and delivering innovative defence technologies to military and law enforcement communities around the world.

 DefendTex are seeking an experienced Mechanical Engineer to join an expanding team working on the development of cutting-edge Defence technologies. Specifically, the role will be focused on design and development of a range of novel unmanned systems technologies. The successful applicant will be required to lead the design of the products including any support systems, prepare and review 3D CAD models of unmanned systems sub-components, assemblies and tooling as well as prepare and review detailed manufacturing drawings. The successful applicant will act in a Team leader role for a small multidisciplinary team of approximately 5 engineers.

 The successful applicant will evolve the existing designs based on empirical test data to optimise the system’s performance. They will also provide insight into materials and manufacturing improvements where appropriate. These designs will require the integration of electronic systems, as well as the use of a variety of lightweight high-performance materials. The successful applicant will be required to develop flight test plans and run test campaigns at regular intervals. The role may also require the assembly and handling of novel ammunition and weapon components.

Initially the role will be working on the development of small unmanned systems, however, there will also be opportunities to contribute to other technologies under development at DefendTex.
