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.
THE ROLE
We are looking for an experienced senior 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).
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
