Senior Firmware Engineer (Wireless)

Senior Embedded Software Engineer – Cellular / DSP

Bedfordshire | Hybrid

This is an engineering team where decisions aren’t pushed up the chain — they’re made by the people doing the work.

The structure is flat.
The expectation is ownership.
And the engineers here don’t just build systems — they shape how they’re built.

You’ll be working on live wireless systems, taking real cellular signals and making them usable in unpredictable environments.
Not simulations. Not ideal conditions.
Real-world RF problems that need solving properly.

The Role

You’ll operate across the embedded stack, with the freedom to approach problems properly — not within rigid boundaries:

• Embedded C firmware development
• Cellular protocol layers (MAC / RLC)
• DSP implementation where needed
• Integration with RF hardware, DSPs and FPGA platforms

You won’t be siloed.
You’ll work directly with RF, hardware, FPGA and DSP engineers to solve system-level challenges.

The Environment

A ~20-person engineering team spanning RF, DSP, FPGA, hardware and software.

What makes it different:

• Engineers self-manage — no micromanagement
• Decisions are made within the team, not escalated through layers
• Collaboration is direct and cross-disciplinary
• You’re trusted to own problems end-to-end, not just your piece

For the right person, that level of trust — and responsibility — is genuinely liberating.

Why This Role

• Engineers influence technical direction, not just delivery
• Work on real-world wireless systems, not controlled environments
• Broad exposure across embedded, DSP, RF and system integration
• Employee-owned structure — you have a real stake in the business

What Matters

• Strong Embedded C experience
• Exposure to cellular systems (ideally MAC / RLC or similar layers)
• Experience working close to hardware / performance-critical systems
• Comfortable operating with autonomy and accountability
• DSP implementation experience is highly beneficial

Package

• £75,000 – £85,000 base
• ~15% profit-related bonus
• 7% non-contributory pension
• Hybrid working (typically 3 days onsite)

If you prefer environments where everything is defined for you — this probably isn’t the right fit.

If you want ownership, influence, and the freedom to solve complex problems properly, it’s worth a conversation.
