RF Electronics Engineer

About the position

Would you like to work on advanced robotic systems or sensors for autonomous drones? What about mobile ad-hoc radio networks, messaging systems for the emergency services or internet of things sensors? How do you fancy airborne or space-based radars? These are all current or recent projects at Plextek and we need the brightest minds joining our diverse team to deliver them.

Our work is largely driven by technical development and innovation. One of the great advantages of working here is that no two projects are the same. If you are an enthusiastic, adaptable and motivated person with a background in engineering, who thrives on variety, enjoys learning new skills and facing exciting challenges then this is the place to be.



We are looking for an experienced RF electronics engineer to join the team, possessing the experience necessary to play a key role in designing, building and testing new RF-based systems and products. In addition to the technical skills necessary, you will be comfortable explaining complex technical matters to non-technical customers.

The role provides the opportunity to use your technical skills to work with a team to follow exciting new ideas through from concept into reality. You will have the satisfaction of working with a supportive and experienced team of subject matter experts, in a state-of-the-art electronics lab containing the latest test and measurement equipment (spectrum/network analysis/anechoic chambers).

Key desired skills and experience

  • BEng or preferably MEng in electronics engineering (or similar discipline)
  • 3+ years post-graduate experience in designing, building and testing RF-based circuits (e.g. for radios and/or radars)
  • Good microwave, RF, analogue and digital circuit design and simulation skills. Whilst not essential, experience of mm-wave frequency design would be advantageous.
  • Some radio and/or radar systems knowledge is essential.
  • PA / LNA / Filter and frequency synthesiser design
  • Antenna design



In return, we offer a competitive package and a stimulating environment that will encourage you to be your best. Salary and job title will be based on the level of the candidate’s experience and expertise. We provide all the training, professional development and support that you need to complete your projects, including a number of dedicated training days per year. We are a versatile business and are able to support career progression in many dimensions including technical, commercial and managerial.



Plextek provides unique solutions for our customers by solving today’s hardest engineering problems in sensing, data collection & communications. Our customers span a wide range of markets including healthcare, internet of things, defence, security and automotive.

We are based just south of Cambridge with easy road and rail routes to the vibrant city centre. We provide a friendly and supportive working environment including regular on-site and off-site social events.
