Location: Bradford, West Yorkshire (Hybrid)

An exciting opportunity has arisen for a Senior RF Engineer to join a specialist UK electronics company working on advanced RF and microwave systems.

The company designs, develops, and delivers high-performance RF solutions across multiple industries, including defence, aerospace, and communications.

This role is ideal for a technically skilled engineer with hands-on experience in RF design, testing, and integration who thrives in a collaborative, high-precision engineering environment.

Main Responsibilities of the RF Engineer - Senior (based in Bradford):

• Design, analyse, and optimise RF circuits and subsystems across microwave frequency bands (1GHz-18GHz).


• Develop and implement low-noise amplifiers (LNAs), power amplifiers (PAs), mixers, filters, oscillators, and synthesizers.


• Conduct RF system architecture and front-end design, balancing performance, cost, power, and size.


• Execute RF simulation, modelling, and statistical analysis using industry-standard tools (Keysight ADS, AWR Microwave Office, CST, HFSS).


• Perform RF testing and validation using spectrum analysers, VNAs, signal generators, power meters, and noise figure analysers


• Troubleshoot RF issues at component, PCB, and system level and correlate lab measurements with simulations.


• Collaborate with PCB layout engineers to ensure controlled impedance, grounding, shielding, and overall RF performance.


• Support EMC, EMI, and regulatory compliance testing and certification activities.


• Mentor junior RF engineers and contribute to technical design reviews, reports, and customer documentation.

Requirements of the RF Engineer - Senior (based in Bradford):

• Proven experience in RF design, 1GHz-18GHz frequency range, with LNAs, PAs, mixers, filters, oscillators, and synthesizers.


• Strong understanding of RF system design, linearity, noise figure, intermodulation, and spectral purity.


• Hands-on experience with RF test equipment and measurement techniques.


• RF PCB layout knowledge and experience integrating RF designs into larger mixed-signal or digital systems.


• Proficiency with RF CAD/simulation tools (Keysight ADS, AWR Microwave Office, CST, HFSS).


• Experience with scripting/programming for RF analysis or test automation (Python, MATLAB, LabVIEW).


• Excellent problem-solving skills, attention to detail, and ability to communicate complex RF concepts clearly.


• Experience in mentoring or leading RF work packages preferred.


• Understanding of product development lifecycle, cost, risk, and schedule management.


• Ability to work independently as well as collaboratively across multidisciplinary teams.
