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 and thrive in a fast‑paced, hands‑on environment, this opportunity is built for you. The key to this position is having both system‑level design experience and hands‑on RF design and test of the system.
This is a 12‑month Hybrid 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 analyzers, 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.
* RF PCB layout skills using Altium or equivalent.
* Familiarity with Python/MATLAB for automation and data processing.
* EM simulation experience (HFSS, CST).
* Hybrid role just south of Henley‑on‑Thames
* Commutable from Reading, Oxford, High Wycombe, Maidenhead, and surrounding areas
* Length: 12 months (with potential to extend)
