Senior C++ Software Engineer | 5G / High-Performance Computing

Southampton | Hybrid | Bonus + Equity

What happens when your C++ code has to process wireless signals in real time, rather than simply pass a unit test?

A UK communications technology company is expanding its engineering team and is looking for a Senior Software Engineer to work on the platform behind its 5G physical-layer technology.

This is low-level, performance-focused software engineering.

You'll be developing and optimising C/C++ running on x86 and ARM platforms, where latency, throughput and efficient use of compute resources genuinely matter.

Think:

* C/C++ and Linux

* x86 and ARM

* Real-time signal processing

* PCIe and hardware/software integration

* Performance optimisation

* High-performance and embedded computing

You'll work alongside software, algorithm and hardware engineers figuring out how complex communications technology can actually run efficiently on real hardware.

What sort of background?

You'll probably come from wireless communications, embedded systems, telecoms, semiconductor or high-performance computing.

Strong C/C++ and Linux experience are important, as is experience developing software close to the hardware.

If you've also worked with DPDK/BBDEV, SIMD, Intel AVX, ARM NEON, C++20, embedded RTOS or 5G PHY, even better.

You don't need everything on that list.

Why look at it?

Because this isn't another backend or application software role.

The interesting problems happen when sophisticated signal-processing algorithms meet real-world latency, throughput and hardware constraints.

If you enjoy working close to the hardware, profiling and optimising C/C++ and figuring out where the next bit of performance is going to come from, let's talk.
