Principal RF Engineer

Company: Cirrus Selection
Apply for the Principal RF Engineer
Location: Stevenage
Job Description:

Overview

You fire missiles indoors. Not literally, but close enough that it counts.

Team

The Hardware-in-the-Loop team at one of Europe’s most respected defence primes runs the most complete test of a missile short of an actual firing. They build real-time simulations that wrap around live missile hardware, and they do it with a small, expert team who genuinely know their stuff.

Role

You need an RF engineer who can design, develop, and maintain complex RF equipment, work across electronics and software, and hold their own in multi-disciplinary teams where the stakes are real.

What we expect

You don’t need to tick every box. Broad RF experience matters more than a perfect CV. If you’ve worked across RF design and testing, system integration, real-time applications, or hardware with embedded controllers, this could be a serious conversation worth having.

Location & Remuneration

The role is based in Stevenage. Mostly on-site, for reasons you’ll understand once you know the work. Up to £55k, a decent bonus, 14% pension, and flexi leave that’s actually flexible.

Qualifications

SC clearance required. British citizenship essential.

Why consider this

If you’ve been in the same seat for a while and wondered what a proper technical challenge looks like, this is worth a look.
