Senior Developer

The opportunity

As a Senior C++ Developer, you won’t be maintaining legacy code or adding features at the edges. You have the option to work fully remote or partially remote with access to the client’s offices.

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.

• 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.

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.

• 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.

• 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

• 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

• 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

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.
