The backdrop for radio frequency (RF) engineering roles is an engineering labour market under real strain. Right now, 76% of engineering employers struggle to recruit for key roles, with technical and specialist skills topping the list, according to the Institution of Engineering and Technology. RF engineering sits squarely in that specialist bracket, which is why pay and hiring behaviour across defence suppliers are both moving.
Churn is the other half of the story. 79% of UK technical professionals plan to change employers in 2026, according to recruitment firm Rise Technical's 2025/26 Insights Report, surveying over 500 employers and 1,000 candidates. When most of your target engineers are open to a move, the people you want are already being approached. Pay signals, then, are as much about retention as they are about attraction.
There is a pipeline warning too. In engineering, entry-level hiring has fallen to -19% while senior hiring sits at -10%, a 9-percentage-point gap, according to a GOV.UK snapshot of entry-level hiring in the UK. For RF specialisms, that thinner junior intake today means fewer home-grown senior engineers in a few years, which keeps upward pressure on pay for the people who already have the skills.
RF engineering is a scarce, resident-led specialism. For the engineering profession, the vast majority of new hires come from the resident labour force, indicating low reliance on international recruitment, according to GOV.UK's review of professionals in IT and engineering. In defence specifically, security clearance and nationality requirements narrow that pool further, so suppliers are competing for a small set of eligible engineers.
On the headline numbers, the picture is nuanced. Pay for engineering professionals on the Skilled Worker route is broadly in line with the UK average, while top technology firms can pay sizeable wages to skilled migrants, leading to wages far above the salary threshold, according to the Migration Advisory Committee's review of professionals in IT and engineering. In plain terms: average engineering pay looks ordinary, but the firms that most need rare skills pay well above it. RF roles at defence suppliers behave like the second group, where the premium tracks scarcity and clearance, not the average.
The practical signal for employers is this. When 79% of technical professionals plan to move in 2026 per Rise Technical's 2025/26 Insights Report, your pay offer is being benchmarked constantly by people who could leave. Review it often, and pair it with the things RF engineers value: interesting programmes, clear progression and a fast, respectful process.
Start with speed. With 76% of engineering employers struggling to recruit for key roles according to the IET, a slow process is where good RF candidates fall away. Decide your must-haves before you open the role, line up your interviewers and commit to quick feedback. Clearance and vetting already add time, so keep every stage you control short.
Be precise about the brief. RF covers a wide span, from antenna and microwave design to EW, radar and systems integration, and a vague advert attracts the wrong people. Name the frequency bands, tools and programme context, and be clear on clearance level and eligibility up front so no one wastes time.
Protect your pipeline. The 9-point gap between entry-level and senior engineering hiring in the GOV.UK snapshot is a signal to keep investing in junior and transferable-skills routes even while you chase senior hires, or you simply move the shortage a few years down the line. And because most engineering hires come from the resident workforce per GOV.UK, your competitors are fishing in the same pond, so a strong employer story and a clean candidate experience are what set you apart.
When the pool of cleared, specialist RF engineers is small and most are open to a move, you need to reach the right people fast and manage the process end to end. Our recruitment agent manages recruitment end to end for 8% on a successful hire, with no monthly fee and no upfront cost, through Reed.ai. That fee is about one thing: finding the right person and running the whole process so you can focus on the programme. Tell us the role, the skills and the clearance level, and let us surface your shortlist today.
