Job description

RF Engineer - Senior

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.

Responsibilities

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

• Proven experience in RF design, 1 GHz–18 GHz 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.
