The Principal Mechanical Engineer is a key role that leads the mechanical engineering aspects of the development of new radar technologies. Reporting to the Project Engineering Manager, this role must have an expert general mechanical knowledge with experience in the design, build, integration and test of complex mechanical systems.The holder will themselves be a subject matter expert in at least one area of Mechanical Engineering, for example, Computational Fluid Dynamics, Finite Element Analysis, Structures or Thermal Systems. They may also hold Mechanical Design Authority for the Future Radar Products.Experience and knowledge of the design, build, test and use of composite structural materials is essential.Familiarity with the use of relevant modelling and simulation tools for analysis of structure behaviours under static and dynamic load, shock and vibration is essentialExperience and knowledge of the design and implementation of mechanical systemsFamiliarity with the content, applicability and use of relevant Standards is highly desirableExperience and knowledge of engineering lifecycles from requirements capture and derivation to in-service support is highly desirable.Typical duties :Provide leadership, direction and technical expertise to a small team of mechanical/CAD engineers working on the development of new radar productsOrganise and oversee work packages within the projectEffectively liaise with the project engineering manager, the project manager and the project
