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 youll 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. Theyre hiring Senior Software Engineers and Principal Software Engineers , depending on depth of experience and appetite for technical leadership. What youll be working on Youll 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 If you enjoy low-level performance work, youll feel right at home.
