Job description

Software Engineers – Real-Time Wireless Systems (Senior & Principal Levels)

Permanent | £75k–£100k + Bonus + Equity | Hybrid (Southampton)

If your idea of good engineering is squeezing every last cycle out of a CPU, building software that talks to hardware at speed, and solving real wireless signal‑processing problems… you’ll probably get on well here.

This team designs and builds high‑performance software for wireless communication systems — 5G, satellite comms, and advanced baseband processing. The real, high‑throughput, low‑latency kind.

They’re hiring Senior Software Engineers and Principal Software Engineers , depending on depth of experience and appetite for technical leadership.

What you’ll be working on

You’ll be turning clever DSP and comms algorithms into real‑time production software running on x86 or ARM , and building high‑performance APIs that interface with hardware acceleration. Expect a mix of :

• Real‑time C / C++ for wireless signal processing
• Linux, DPDK, PCIe, SIMD, modern C++
• Hardware / software integration and performance tuning
• Designing, testing, optimising and owning your software through to delivery
• Working with DSP, FPGA, verification and systems engineers
• Improving tooling, processes and engineering flow as the team scales
