Electronics Design Engineer – High-Speed PCB & FPGA
London | Hybrid | £55,000–£65,000 + benefits
What if the hardware you designed was part of the security boundary itself? We’re recruiting for a specialist cybersecurity technology business developing hardware-enforced security products for defence, government, and other highly secure environments. This isn’t a role where you’ll spend your time maintaining legacy designs or simply reviewing somebody else’s PCB work. You’ll be developing complex electronics from concept through to working, qualified hardware – designing circuitry, laying out PCBs, bringing boards to life in the lab, solving problems, and supporting products through validation and certification.
The role
You’ll work across the electronics development lifecycle, including:
- Multilayer, high-speed digital PCB design
- Schematic capture and physical PCB layout
- PCB stack-up, controlled impedance, and signal integrity
- Differential signalling, grounding, termination, and high-speed routing
- Component selection and circuit design
- Prototype build, board bring-up, and debugging
- Verification and validation
- EMC/EMI and environmental qualification
- Supporting external certification and test-house activity
- Design for manufacture and production support
- Working alongside FPGA, software, and wider engineering teams
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.
There is also significant use of FPGA technology, so experience with VHDL or Verilog would be particularly valuable.
What are we looking for?
Ideally, you’ll have around 3–5 years’ commercial electronics/hardware development experience and a degree in Electronics, Electrical Engineering, or a closely related discipline.
Experience with Altium Designer would be particularly useful, alongside some combination of:
- High-speed digital design
- Multilayer PCB layout
- Controlled impedance
- Differential pairs
- Signal integrity
- FPGA/VHDL
- EMC/EMI
- Hardware validation
Experience within defence, aerospace, cybersecurity, communications, or another highly regulated engineering environment would also be advantageous.

Why is this one different?
The technology is the interesting part. This business develops high-assurance cybersecurity technology where security can be physically enforced in dedicated hardware, rather than relying solely on conventional software controls. The technology is used within defence, government, intelligence, and mission-critical environments, including the secure movement of information between networks operating at different security classifications.
For an electronics engineer, that creates an unusual opportunity: the PCB and FPGA technology you develop isn't simply there to support the product. The electronics is part of what makes the product secure. If you’re an Electronics Design Engineer who enjoys owning hardware from initial design through to working, tested product, we’d be interested in hearing from you.
