RF and Microwave Design Engineer

Contract: Fixed term until January 2027, full time 

Salary: £39,906 per annum

Location: Liverpool, hybrid (minimum of 3 days on site per week)

Role Purpose
The RF and Microwave Design Engineer will play a critical role in the design, development, and integration of advanced microwave sensing systems for next-generation healthcare diagnostic and monitoring technologies within the Infection Innovation Technology Laboratory (iiTECH). The postholder will be responsible for developing and optimising microwave and radio-frequency (RF) circuits, antenna design, and sensing architectures that underpin innovative handheld and wearable devices aimed at the detection, monitoring and prevention of infectious diseases.

Working as a part of multidisciplinary research and development team, the appointee will contribute to the full lifecycle of sensor technology innovation from conceptual design, simulation and prototyping to experimental validation and clinical translation. The role will involve close collaboration with electronics engineers, biomedical scientists, applied machine learning engineers and clinicians to ensure the developed systems are robust, accurate, and clinically applicable.

Key responsibilities include design and characterisation of RF/microwave circuits, antennas design, development of microwave-based sensing and imaging modalities, integration with digital and embedded systems, and implementation of rigorous quality assurance and regulatory standards.

This position offers a unique opportunity to push boundaries of microwave sensing, contribute to technological innovation in healthcare diagnostics, and develop transformative tools that address global health challenges.
