Mechanical Design Engineer
On-siteSedgefield, England, United Kingdom
Job Summary
Design precision mechanical components and assemblies for RF modules, including lightweight enclosures, heatsinks, and waveguide architectures. Perform thermal analysis via CFD and structural validation using FEA to ensure reliability for aerospace and defence applications. Collaborate with RF and electronics teams to optimize cavity geometry, surface finishes, and material selection for high-frequency performance. Develop designs for manufacturability using CNC machining, die-casting, and additive manufacturing while generating GD&T drawings and assembly documentation. Support prototype builds, environmental testing, and supplier development throughout the product lifecycle. Manage engineering drawings and design reviews in accordance with ISO and NPI processes.
