RF and Microwave Design Engineer

Reference: DEC

Expiry date: 23:59, Mon, 5th Jan 2026

Location: Liverpool

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.

Key Responsibilities

• Design, simulate and prototype RF and microwave antennas, circuits for healthcare sensor applications targeting the detection, monitoring and prevention of infectious diseases
• Develop antenna resonators optimised for biomedical sensing and material characterisation
• Use electromagnetic simulation tools namely CST to model, optimise and validate sensor performance across relevant frequency ranges.
• Conduct iterative testing, calibration and refinement of designs to ensure sensitivity, stability and reproducibility
• Collaborate with data scientists and electronics engineers to integrate microwave structures with electronics and AI and ML algorithms for real time data collection
• Support the development of data pipelines and algorithms for real time signal analysis, imaging and feature extraction from microwave sensor outputs.
• Evaluate system level performance, including signal to noise ratio, frequency response and environmental robustness, ensuring compatibility with downstream AI and data processing modules
• Develop and implement rigorous testing and characterisation protocols to assess microwave sensors reliability, calibration accuracy and long term stability.
• Design and prototype circuitry in alignment with environmental and electromagnetic compatibility (EMC) testing to ensure robust operation under varied physiological and clinical conditions.
• Document design procedures, test outcomes and quality assurance measures to support translational deployment
• Work closely with partners in academia, industry and global health organisations to align research objectives.
• Coordinate with clinical teams to ensure technologies address user needs and healthcare priorities.
• Publish research findings in high impact academic journals and present at international conferences.
• Contribute to translating research findings into practical applications by supporting collaborations with industry partners
• Identify potential sources of research funding and contribute to the process of securing funds

You will have

• PhD or equivalent industrial experience in Electronics Engineering, Electrical Engineering, Physics, Biomedical Engineering, or a closely related discipline, with a focus on RF/microwave circuit design or sensing systems.
• Proven expertise in the design, simulation and prototyping of RF and microwave circuits, antenna resonators for sensing applications.
• Proficiency in analogue, digital and mixed signal circuit design, including RF front end development, impedance matching and high frequency measurement techniques
• Experience with electromagnetic and network analysis instrumentation (e.g. VNA, spectrum analysers, signal generators) for circuit testing, calibration and characterisation
• Demonstrated ability to conduct experimental validation, iterative prototyping and performance optimisation of sensing systems.
• Strong track record of publishing research in peer reviewed journals or writing industrial reports.
• Excellent communication skills, including the ability to present findings clearly to diverse audiences

About LSTM

Founded in 1898 and the oldest of its kind in the world, the Liverpool School of Tropical Medicine (LSTM) is an internationally recognised centre of excellence for teaching and research in tropical diseases. Through the creation of effective links with governments, NGOs, private organisations and global institutions and by responding to the health needs of communities, LSTM aims to promote improved health, particularly for people of the less developed/resource poorest countries in the tropics and sub tropics.
