Job description

Software Engineers

Real-Time Wireless Systems (Senior & Principal Levels)

Permanent | £75k£10,000 + 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

• 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, you’ll feel right at home.

Whats 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 :

£75k£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 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 lets have a conversation.
