Our client is a specialist RF and antenna technology company building a new R&D; capability in Lincoln, UK. This is a small, high-calibre engineering group working directly with senior technical leadership on complex RF and antenna challenges. The focus is on real product development, not theory, spanning antenna systems, RF subsystems and mixed-signal electronics, with collaboration across international engineering teams.
The Role – Junior RF & Antenna Design Engineer
As a Junior RF & Antenna Design Engineer, you’ll work closely with experienced engineers on the design and development of RF and antenna systems across a wide frequency range (HF to SHF). This Junior RF & Antenna Design Engineer role is hands-on - supporting simulation, design, prototyping and testing of real hardware, not just modelling.
You’ll be exposed to:
Antenna and RF subsystem design (HF–SHF)
Electromagnetic simulation (CST, HFSS, FEKO or similar)
RF circuit design and mixed-signal electronics
Lab-based testing, measurement and prototype build
Collaboration with general engineering teams and end customers




What they’re looking for
Degree in Electronic Engineering (ideally with RF/microwave or electromagnetics focus)
Some exposure to RF/antenna design - academic or industry
Familiarity with tools like CST, HFSS, ADS, AWR or similar
Solid grounding in electromagnetics and RF fundamentals
Practical mindset - comfortable building, testing and iterating hardware
Someone who can learn quickly and contribute in a fast-moving environment
Why consider this Junior RF & Antenna Design Engineer role
Direct access to senior technical leadership and complex design work
Strong learning curve in a genuinely hands-on RF environment
Small team, high impact - your work won’t be diluted
Exposure to international projects and real-world applications
A good step for someone early in their career who wants proper RF design experience, not just simulation work
