Senior C++ Developer

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 l...
