Senior RF Engineer | RF, Microwave & mmWave Design | Cambridge (Hybrid) We’re looking for a Senior RF Engineer to join a specialist team designing and delivering high-performance RF, microwave, and millimetre-wave subsystems for aerospace, defence, space, and advanced communications applications. You’ll take ownership of RF circuit design, simulation, measurement, and validation at component and subsystem level — producing hardware that meets stringent electrical, thermal, and manufacturing standards. This is a hands-on technical role focused on design quality, test, and real engineering depth — not management layers. Responsibilities • Design and develop RF and mmWave circuits, components, and subsystems, • Perform simulation, analysis, and optimisation using ADS, HFSS, CST, or equivalent tools, • Conduct RF measurements, characterisation, and validation of prototypes and production hardware, • Diagnose and resolve complex performance and integration issues, • Produce design documentation, test procedures, and data packs for internal and customer reviews, • Support transfer from prototype through to manufacturing and qualification, • Work cross-functionally with mechanical, process, and systems engineers to ensure design robustness Requirements • Degree (or equivalent experience) in Electrical/Electronic Engineering, • Proven background in RF or microwave circuit design, ideally including mmWave, • Experience with S-parameters, impedance matching, filters, amplifiers, mixers, and LNAs, • Proficiency in simulation and modelling (ADS, AWR, HFSS, CST, or similar), • Skilled with VNA, spectrum analysers, power meters, and signal generators, • Understanding of DfM, DfT, and high-reliability design processes, • Experience taking designs through concept, layout, bring-up, and verification Desirable • Experience with GaAs, GaN, or SiGe technologies, • Familiarity with waveguide, coaxial, or surface-mount RF packaging, • Understanding of EMC and environmental test requirements, • Background in defence, space, or high-spec communication systems Package Competitive salary and benefits package, plus clear scope to progress in a technically advanced and growing RF engineering team based in Cambridge.
