RF Design Engineer

Role: RF Design Engineer Location: Belfast - Relocation Required Working pattern: Hybrid, 3 days onsite Salary: £65,000 - £75,000 An established defence and electronic engineering organisation delivering complex, high-technology solutions across critical engineering programmes. The business supports the development and integration of advanced electronic systems where robust design, verification and operational performance are essential. We are seeking an experienced RF Design Engineer to support the design, development and validation of RF and mixed-signal electronics for demanding defence applications. The role offers practical ownership across the RF development lifecycle, from component selection and schematic design through to PCB integration, laboratory testing and system-level validation. You will work closely with electronics, PCB layout, systems, firmware and test specialists to develop reliable, production-ready solutions. Key responsibilities Design and develop RF analogue and mixed-signal electronics for complex engineering systems. Develop transceiver and RF front-end architectures using monolithic RF chipsets, including MMIC, SiP and SoC-style devices. Design RF schematics, component selections and impedance-matching networks against defined system requirements. Work with PCB layout engineers on signal integrity, grounding, shielding, routing and manufacturability. Plan and execute laboratory verification using VNAs, spectrum analysers, RF signal generators, power meters and oscilloscopes. Experience across every aspect of the role is not essential; on-the-job learning and support will be available for candidates looking to broaden their RF design capability. If you are an experienced RF Design Engineer with a background in RF electronics, wireless hardware, transceiver development, impedance matching, PCB integration or laboratory validation across defence, aerospace, telecommunications or other high-technology environments, please apply with your CV or contact us for a confidential discussion.
