Nine years ago, a small team working alongside researchers at University of Oxford set out to solve a problem most of the world didn’t yet realise it had. Billions of machines were beginning to talk to each other — in factories, power grids, transport systems, defence networks and smart cities. But they were doing so through architectures built for a different era: centralised, fragile, and increasingly exposed. So, they built something different.
Today, this UK tech company holds patented cryptographic technology that enables fully decentralised, post Quantum secure interoperability between devices — operating at the edge, without relying on always-on central connectivity. It works in untrusted environments. It enables real-time communication and narrow AI across full-scale industrial systems. And it is quietly moving from academic breakthrough to global security relevance.
Now they need a senior C++ engineer who can operate where this technology truly lives — deep in the network stack.
The Role: Where Packets Become Trust
This is not application-layer C++. This is not framework-driven development. This is low-level, network-centric engineering, working primarily across OSI Layers 2 and 3, where routing decisions, tunnelling strategies and packet behaviour determine whether distributed systems can operate securely at scale.
You will design and build software that ultimately runs on millions of industrial edge devices — enabling:
- Secure cloud ↔ edge communication
- Device-to-device authentication
- Decentralised routing and interoperability
- Robust deployment mechanisms for edge environments
You will shape technical architecture, contribute to governance models, and help standardise innovative security solutions that could define the future of industrial IoT.
Why This Matters
This is a nine-year-old UK technology business that has moved from academic roots to patented, commercially relevant security infrastructure. It is no longer a concept. It is not a slide deck. It is production-grade technology preparing for global scale.
The successful candidate won’t just write code. They will help determine how critical infrastructure, industrial systems and smart cities authenticate and communicate for decades to come. You’ll receive a competitive base salary, significant equity, and the chance to work on technology that sits at the intersection of networking, cryptography and national-scale resilience.
If you are a serious C++ engineer who understands packets, routing, tunnelling and kernel-level behaviour — and you want your next role to genuinely matter — this may be worth a conversation.
