Lead RF Engineer

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 Hybrid working 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:

Hybrid Working 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
