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.
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
