.

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.

• 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

• 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: £75k £80k + bonus + equity

• 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

• 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.

• 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 23 days on‑site in Southampton

If you’d like to explore the Senior or Principal path or aren’t sure which is the best fit, let’s have a conversation.
