Senior Radio Frequency Engineer

Outside IR35 Contract – RF Engineer (mmWave / Ku & Ka Band) – 12 Months We’re on the hunt for a Senior-level RF Engineer to take the lead on cutting-edge mmWave RF circuit design for mission-critical SATCOM systems. If you're an expert in RF engineering – particularly across the 10–30GHz range – and thrive in a fast-paced, hands-on environment, this opportunity is built for you. The key to this position is having both the system level design experience, transceiver/transmitter design and hands on RF design and test of the system. This is a 12-month Outside IR35 contract with a leading technology client based just south of Henley-on-Thames. You’ll be joining a highly skilled engineering team working at the forefront of satellite communication, delivering RF subsystems with global reach and real-world impact. What You’ll Be Doing: RF Subsystem Design – Architect and design Ku/Ka-band front-end modules (LNAs, PAs, filters, mixers, frequency converters) for next-gen SATCOM ground terminals. Simulation & Analysis – Run system analysis and propagation modelling using System Vue , ADS , and MATLAB . Prototyping & Testing – Take designs from schematic through to test and validation with VNAs, signal generators, satellite modems, and more. EM Simulation – Conduct high-fidelity simulations using HFSS , Keysight ADS , etc. Data-Driven Insight – Analyse and validate simulation and real-world data using MATLAB , Python , or similar tools. Collaborative Integration – Work closely with modem, antenna, mechanical and manufacturing teams to optimise at the system level. Documentation & Compliance – Create clear technical documentation and ensure all designs meet FCC, ITU, ETSI, EMC and ruggedisation standards. ✅ You’ll Need: 7–8 years’ experience in RF/Microwave design – ideally for aerospace communications infrastructure Strong hands-on design experience across Ku and Ka bands (10–30GHz). Deep expertise in RF hardware (LNAs, mixers, VCOs, PAs, etc.) and performance optimisation (noise, linearity, impedance matching). Proficiency with RF test equipment : spectrum/network analysers, signal generators, etc. Simulation tool fluency: ADS, System Vue, MATLAB . Strong understanding of link budgets , phased arrays, and RF propagation . A knack for balancing high performance with DFM and cost-effectiveness. Nice to Have: RF PCB layout skills using Altium or equivalent. Familiarity with Python /MATLAB for automation and data processing. EM simulation experience (HFSS, CST). Location: Onsite role just south of Henley-on-Thames Commutable from Reading, Oxford, High Wycombe, Maidenhead, and surrounding areas Contract Details: Length : 12 months (with potential to extend) Status : Outside IR35 Start : ASAP / negotiable
