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 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.
