Our Client
Our client is a fast-growing UK engineering business developing advanced RF, sensing and communications technology for demanding operational environments. Based in Bristol, the role operates on a hybrid basis with a minimum of 3 days per week onsite. Candidates must also be eligible for UK SC clearance.
The Role
As a Principal RF Engineer, you will take ownership of RF and mixed-signal hardware from initial architecture through schematic design, PCB implementation, bring-up and validation.
You will work across the full RF signal chain, including antenna interfaces, amplification, filtering, frequency conversion, signal conditioning and high-speed ADC/DAC integration.
The Principal RF Engineer will also work closely with FPGA, embedded software and signal-processing engineers, ensuring the hardware delivers the required system-level performance.

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.
- RF front-end and signal-chain design
- Mixed-signal hardware incorporating high-speed ADCs and DACs
- Multi-layer RF PCB and schematic design
- RF component selection and integration
- Hardware bring-up, debugging and optimisation
- RF performance measurement using VNAs, spectrum analysers, signal generators and oscilloscopes
- Integration with FPGA and SDR platforms
What They Are Looking For
Our client is looking for an experienced RF engineer who has designed complete RF or mixed-signal boards rather than working solely at system or simulation level.
You Should Have Strong Experience With
- RF analogue hardware and signal-chain design
- Mixers, amplifiers, filters, oscillators and gain stages
- High-speed ADC/DAC integration
- RF and mixed-signal PCB design using Altium, KiCad or similar
- RF layout, impedance control, grounding, isolation and signal integrity
- Hardware bring-up and laboratory debugging
- RF performance metrics including gain, noise figure, bandwidth and dynamic range
Get help with your application
Your very own career expert that helps elevate your application to the next level.
Experience with SDR, FPGA/Zynq platforms, sensing, electronic warfare, communications or low-SWaP systems would be useful, but is not essential.
Why Consider It?
This is a genuinely hands-on Principal RF Engineer position with significant technical ownership.
You will be working on complex RF hardware that needs to operate reliably outside controlled laboratory environments, while remaining close to the design, build and test work.
The company has strong engineering and manufacturing capability in Bristol, with RF, FPGA, embedded and signal-processing engineers working closely together.
The role is hybrid, with a minimum of 3 days per week onsite in Bristol, and candidates must be eligible for UK SC clearance.
