Senior Developer

The opportunity

As a Senior C++ Developer, you won’t be maintaining legacy code or adding features at the edges.

You’ll be designing and building core systems that will ultimately run on millions of industrial edge devices, shaping how they authenticate, communicate, and trust one another — from the edge inward.

This is deep, low-level engineering with genuine real-world consequences.

You’ll work on:

High-performance C++ systems that must be secure, resilient, and elegant

Message- and event-driven architectures spanning cloud, edge, and device-to-device communication

Decentralised security models that challenge conventional IoT thinking

Deployment, configuration, and governance approaches that actually work at industrial scale

You’ll have meaningful influence over architecture, standards, and long-term technical direction.

Company Description

Across critical national infrastructure, industrial systems, defence, and smart cities, billions of devices communicate every day — often insecurely, often via fragile, centralised models that were never designed for today’s threat landscape or scale.

This early-stage UK technology company exists to change that.

Working alongside leading academic researchers, the team has created a radically new, edge-native authentication and security platform. It enables real-time communication and narrow AI across vast industrial networks without relying on always-on central connectivity.

It’s decentralised.

It’s post-quantum secure.

It even operates in untrusted environments.

And it’s already real.

What you’ll be trusted to do

Design and own technical architectures across cloud and edge environments

Build software enabling secure communication between cloud services and edge devices — and between devices themselves

Create simple, robust deployment and configuration mechanisms for edge-based systems

Help define IoT governance processes and delivery standards

Deliver integrated solutions using Agile and model-driven approaches

Contribute to the standardisation of innovative security and interoperability solutions

This is a senior role in autonomy, responsibility, and impact — not just title.

Qualifications

What we’re looking for

You’ll likely bring 10+ years of deep C++ experience, including:

Designing and building complex systems on Linux and Windows

Working with distributed, cloud-based microservices

Delivering containerised architectures (Docker, Swarm, Kubernetes)

Implementing CI/CD pipelines and Dev Ops best practices

A solid understanding of cryptographic principles (symmetric/asymmetric cryptography, hashing)

Experience thriving in start-up or scale-up environments

You’ll also be someone who:

Documents clearly and automates wherever possible

Communicates well, collaborates easily, and can push back constructively

Enjoys ambiguity, learns fast, and cares deeply about engineering quality

Bonus points (not essential)

Experience with IoT platforms, edge devices, or industrial systems

Exposure to embedded Linux environments (Debian, CentOS, Raspbian, Open Wrt)

API or SDK design experience

Edge-based AI or GPU compute exposure

Familiarity with blockchain concepts

Benefits/Additional Info

Why this role?

You’ll work on genuinely novel, patented technology

Your work will have real-world impact at national and global scale

You’ll join early enough to shape the platform, not just extend it

You’ll receive equity that reflects ownership and contribution

You’ll work with a small, highly capable, mission-driven technical team

If you’re a senior C++ engineer who wants their next role to be meaningful, technically deep, and legacy-defining, this is worth a conversation.
