Job Description
Job Title: Senior RF Test Engineer
Location: Cambridge
Salary: Up to £75k DOE + Benefits
We are recruiting on behalf of an innovative fabless semiconductor company developing next-generation RF technology. The organisation is focused on advancing RF design to solve complex engineering challenges and enable high-performance, manufacturable connectivity solutions.
This is a collaborative, innovation-driven culture where engineering excellence, customer focus, and sustainable product development are central to everything they do.
We are seeking an experienced Senior RF Test Engineer to join a growing development team based in Cambridge, UK.
In this role, you will lead the measurement, characterisation, and validation of advanced RF products, providing critical data and insight to support RF design and systems engineering teams. You will play a key role in ensuring strong correlation between simulation and hardware performance while driving improvements in RF test methodologies, automation, and laboratory best practices.
This position is well suited to someone who enjoys solving complex measurement challenges, defining test strategies, and contributing directly to the successful delivery of high-performance RF modules.
Key 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.RequirementsEducation & Experience
Bachelor's or Master's degree in Electrical Engineering, Telecommunications, or a related discipline.
Strong hands-on experience in RF testing, characterisation, and validation of RF systems or modules.
Practical experience performing 3GPP-based measurements for cellular systems (LTE and/or NR).
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.
Previous experience leading measurement activities or mentoring engineers would be advantageous.Personal Attributes
Proactive and resilient approach to solving complex technical problems.
Strong analytical and troubleshooting skills.
Excellent communication and collaboration skills.
Ability to work effectively both independently and within multidisciplinary teams.
High attention to detail and commitment to delivering quality work
