Full Stack Developer (Edge)

Key areas of responsibility

• Building services that run on edge nodes: lightweight, event-driven, and resilient to intermittent connectivity, with careful attention to memory, CPU, and storage budgets.
• Building control-plane services that coordinate fleets of devices, manage configuration and state, and integrate with backend data and analytics systems.
• Building operator-facing web interfaces for monitoring, control, and decision support, including UIs that remain usable when underlying data is stale or partial.
• Designing and implementing APIs that work well over intermittent connections: idempotent, versioned, tolerant of partial connectivity, and clear about state.
• Wiring up streaming and messaging pipelines between edge and core, choosing the right protocol and the right semantics for each link.
• Integrating with sensors, payloads, and hardware-connected systems, often through unconventional protocols and constraints.
• Contributing to test coverage, CI/CD, and shared engineering practices that keep delivery fast and the codebase healthy.
• Working directly with users to validate that what you've built actually solves the operational problem in front of them.

Key skills, experience and behaviours

• Strong full-stack experience: comfortable building production frontends (React or similar, TypeScript) and production backend services (Go, Python, Node.js, or similar).
• Solid API design experience, both REST and event-driven, with an understanding of where each fits.
• Practical experience with message brokers, streaming, or pub/sub systems (MQTT, NATS, Kafka, or similar).
• Experience working with containers and deploying into orchestrated environments.
• Comfortable on Linux: navigating systems, debugging across the stack, reading logs that nobody curated for you.
• Sound software engineering fundamentals: clean code, automated testing, and a feel for when to optimise and when to leave it alone.
• Awareness of secure software development practices and a proactive approach to identifying and mitigating risks.
• Experience building software that handles sensitive data or operates in security-conscious environments.

• Experience building software for constrained or embedded targets (Raspberry Pi class, single-board computers, IoT, ruggedised hardware).
• Experience with offline-first or intermittently-connected applications, including conflict resolution and reconciliation.
• Familiarity with edge-style stacks: container orchestration at the edge, lightweight messaging, time-series data, telemetry.
• Experience in regulated sectors delivering complex connected systems, such as defence, national security, telecommunications, financial services, or automotive industries.

• Curious and adaptable: Our work crosses domains and you should be comfortable picking up new technologies, languages, and problem spaces.
• Ownership: You finish what you start and you care about the user.
• Pragmatic: You choose solutions that work in practice, and you know when to use the standard tool and when the problem genuinely needs something different.
• Collaborative: You share knowledge generously and you're happy to step into someone else's part of the stack when it helps.
• Resilient: You're comfortable in a fast-paced environment where requirements evolve as we learn more about the operational problem.
• Quality-driven: You take pride in building software that holds up, particularly in environments where retrying is not free.
