Mechanical Design Engineer

Description

• Work with test engineering to develop automated or manual test jigs
• Confirm simulation assumptions through lab measurement and testing
• Develop designs for manufacturability (DFM) and assembly (DFA) using processes including CNC machining, die-casting, additive manufacturing and sheet metal manufacturing
• Design mechanical solutions with consideration for waveguide structures, micro-machined components, PCB integration, and precision alignment
• Support suppliers and production teams, including first-article approval, root-cause analysis, and continuous improvement
• Support environmental and reliability testing (thermal cycling, humidity, vibration, thermal shock, drop tests)
• Oversee build and test of mechanical prototypes
• Perform thermal simulations (CFD, thermal, conjugate) to validate cooling system design and ensure reliable operation of high-power mmWave amplifiers and electronics
• Conduct structural analysis (FEA) for vibration, shock, fatigue, and drop-test conditions where required
• Design precision mechanical components and assemblies for RF modules, including housings, hermetic packages, heatsinks, waveguide structures, and test fixtures
• Generate manufacturing documentation, BOMs, GD&T drawings, and assembly instructions
• Create detailed 3D CAD models and manufacturing drawings
• Collaborate with RF and electronics engineers to optimise mechanical features that influence RF performance (cavity geometry, surface finish, plating, tolerances, material selection)
• Ensure designs meet stringent RF, thermal, mechanical, and environmental requirements (EMI shielding, stiffness, tolerancing, CTE matching, vibration, IP rating)

Requirements

• Strong problem-solving skills and attention to detail
• Familiarity with PCB design constraints, RF shielding, and EMI/EMC considerations
• Ability to manage multiple projects and deadlines
• Experience with PDM/PLM systems and ECO/ECN release processes
• Strong 3D CAD skills (SolidWorks preferred)
• Experience with mmWave or RF product development (waveguides, filters, amplifiers)
• Knowledge of high-volume manufacturing and high-reliability design (defence, space, telecoms)
• Experience in designing high precision mechanical assemblies
• Strong understanding of manufacturing processes and materials (ideally CNC machining of aluminium alloys)
• Ability to work closely in cross-functional engineering teams
• Bachelor's or Master's degree in Mechanical Engineering (or equivalent)
• Excellent understanding of GD&T and engineering drawing standards
• Effective communication skills for cross-functional teamwork and supplier interactions
• Knowledge of RoHS and WEEE compliance
• Experience with thermal management of electronics
• Self-driven attitude with a willingness to learn new tools and processes
• Hands-on experience with FEA tools (SolidWorks Simulation + Flow preferred)
• Knowledge of reliability engineering and qualification standards (MIL-STD)
