Solid understanding of RF fundamentals, including S-parameters, impedance matching, gain, noise figure, and linearity.
Proficiency with RF laboratory equipment such as vector network analysers (VNAs), spectrum analysers, and signal generators.
Experience developing automated, repeatable RF test environments using Python, MATLAB, or similar tools.
Ability to interpret RF schematics, debug hardware, and evaluate RF system trade-offs through practical laboratory testing.
Experience maintaining RF laboratory environments, including equipment calibration, test infrastructure, and measurement best practices.

Responsibilities

Lead RF characterisation and validation activities, conducting detailed measurements to evaluate and optimise product performance.
Design, develop, and maintain robust, repeatable RF test setups for the characterisation of RF modules and systems.
Perform and analyse 3GPP-aligned RF measurements (LTE and/or NR) to assess transmitter and receiver performance.
Provide measurement-driven feedback to RF design and systems teams, ensuring strong correlation between simulation, design expectations, and hardware performance.
Develop and maintain automated test frameworks and scripts to improve measurement efficiency, repeatability, and data integrity.
Define and maintain RF measurement methodologies, laboratory best practices, and documentation standards.
Troubleshoot complex RF measurement setups and hardware issues, supporting development and design reviews with technical measurement insights.
Maintain the RF laboratory environment, including test infrastructure, equipment calibration, and measurement best practices.
