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)
