FULL DESCRIPTION
Senior Firmware Engineer – Wireless / DSP
Location: Bedfordshire | Hybrid
Package: £75,000 – £85,000 base + ~15% profit-related bonus + 7% non-contributory pension
Job Description
You’ll be working on a deployed wireless system used in real-world environments — taking live cellular signals and turning them into something usable. This isn’t lab-based or simulation-heavy. The challenge is making complex RF systems work reliably in the real world.
The Role
You’ll work across the embedded stack:
- Embedded C firmware
- Cellular protocol layers (MAC/RLC)
- DSP implementation where required
- Integration with RF hardware, DSPs and FPGA systems
The Environment
You’ll be part of a 20-person engineering team covering RF, DSP, FPGA, hardware and software. Each engineer is trusted to:
- Self-manage their work
- Collaborate directly with domain experts
- Solve problems without layers of approval or micromanagement
Why This Role
- Work on real-world wireless systems, not controlled environments
- Broad technical exposure across the stack
- High ownership in a small, experienced team
- Unique company ownership structure - the employees are shareholders
What Matters
- Embedded C experience
- Exposure to cellular systems (protocol layers preferred)
- Comfortable working close to hardware
- Able to operate with autonomy
Package
- £75,000 – £85,000 base
- ~15% profit-related bonus
- 7% non-contributory pension
- Hybrid working (typically 3 days onsite)
