You'll be heavily involved in trial activities, prototype builds and testing programmes, giving you the opportunity to see engineering designs evolve into real-world solutions.


You'll create test plans, coordinate testing activities and work with both internal teams and external suppliers to ensure components, assemblies and systems are evaluated effectively. This will allow you to develop valuable experience in product validation, engineering development and project delivery within a defence environment.


You'll also work with engineering drawings, CAD models and Bills of Materials, helping ensure designs are correctly interpreted and prepared for build and test activities. Exposure to systems such as Creo, SolidWorks, Windchill and QAD will provide excellent opportunities to broaden your technical capability across design, manufacturing and product lifecycle management.


Working closely with engineers, technicians and project teams, you'll contribute to solving technical challenges, supporting product improvements and helping deliver innovative vehicle systems that meet demanding customer requirements.
