Edison Hill Search
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 partically remote with access to the clients 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. 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 DevOps 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, OpenWrt) 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. Edison Hill Search are operating and advertising as an Employment Agency for permanent positions and as an Employment Business for interim / contract / temporary positions.
