Principal RF Engineer – Edinburgh (Hybrid)
We’re supporting a leading defence technology organisation in Edinburgh as they expand their RF engineering capability within a next-generation combat air programme. This team is developing advanced multifunction RF systems for future airborne platforms, contributing directly to a major Technology Demonstrator Programme shaping the next era of fire-control radar.
This is a role for an engineer who wants to work at the forefront of RF innovation — designing, testing and integrating complex microwave hardware that will influence future global defence capability.
Hybrid Working
You’ll have flexibility to work from home part of the week, though due to the nature of the projects and security requirements, you should expect to be on-site in Edinburgh around three days per week (varies by project phase).
Reasons to use Rodeo
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.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You’ll Be Doing
As a Principal RF Engineer, you’ll take ownership across the full hardware lifecycle — from concept through to production support — on cutting-edge RF, PCB and module designs. You will:
- Lead RF/microwave sub-system design across concept, detailed design, prototyping, verification and integration
- Produce high-quality, robust designs and documentation, ensuring full configuration management
- Develop multifunction RF PCB and module designs using the latest technologies and manufacturing processes
