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:
- Turning clever DSP and comms algorithms into real-time production software running on x86 or ARM
- Building high-performance APIs that interface with hardware acceleration
- 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, you’ll feel right at home.
What’s different between Senior and Principal roles?
Senior Software Engineers:
- Strong C++/C skills on substantial software projects
- Experience building embedded or high-performance software
- Comfortable contributing to design and delivery across multiple teams
- Mentoring juniors and solving hard engineering problems
- Salary: £70k–£80k + bonus + equity
Principal Software Engineers:
- Everything above, plus…
- Able to lead architecture, design decisions and technical direction
- Comfortable guiding teams of mixed skill levels
- Trusted to take ownership of product-level delivery
- The “go-to” person for difficult performance or system-level challenges
- Salary: £90k–£100k + bonus + equity
What you need (the essentials only):
- Strong C/C++ engineering experience in wireless, comms, DSP, HPC or embedded systems
- Linux development experience
- Experience contributing to (or leading) multi-engineer software projects
- Ability to communicate well with DSP, FPGA and systems engineers
- A scripting language (Python, Jenkins, etc.)
If you’ve worked with ORAN/FAPI, FlexRAN/OAI, DPDK/BBDEV, modern C++20, or SIMD intrinsic optimisation — fantastic. If not, you’ll learn.
Why this is worth a look:
- You’ll work on real, meaningful wireless engineering — not web apps, not feature tickets
- You’ll be around people who care about performance, correctness and elegant engineering
- You’ll get to try new ideas, influence how things are built, and actually see your work in production
- And the package is strong: Up to 20% bonus, Equity scheme, Visa sponsorship & relocation support, PMI, healthcare, pension, Hybrid working: typically 2–3 days on-site in Southampton
