Principal Radio Systems Engineer

Overview

As Principal Radio Systems Engineer, you own the end-to-end radio performance from architecture to field deployment. You translate customer needs into RF hardware specifications and define front-end and antenna requirements, setting performance budgets. You lead link budgets, channel models, and test strategies, guiding design choices through lab, OTA, and field trials. You collaborate with hardware, software and test teams to ensure regulatory compliance and robust product architecture. This role offers impact across high-capacity wireless systems in demanding mobile contexts, with a strong technical leadership element.

Pay / Benefits

• hybrid working
• medical insurance
• health cash plan
• pension matching up to 5%
• life assurance
• enhanced family leave

Responsibilities

• Translate customer requirements into RF hardware specifications and RF front-end/antenna requirements
• Define performance budgets (EIRP, sensitivity, noise figure, linearity, phase noise)
• Define phased-array beam search, tracking and handover for moving platforms
• Develop link budgets and channel models; assess coexistence and interference
• Lead radio test strategy: lab characterization, OTA measurements, field trials, compare results with predictions
• Provide technical direction on radio compliance and contribute to future product architecture

Key requirements

• 10+ years of radio systems engineering experience with products taken from specification to deployment
• Strong microwave or mmWave expertise (link budgets, propagation modelling, performance prediction)
• Working knowledge of phased arrays, beamforming, and RF transceiver impairments impact
• Practical RF measurement experience supported by modelling/analysis in MATLAB or Python
• Familiarity with radio regulatory compliance and ability to explain decisions clearly to customers and colleagues

• clear communicator
• cross-functional collaboration
• problem solving
• mmWave/radio systems engineering
• link budgets
• propagation modelling
