Fullstack Developer Full Time NEW

Full Stack Developer Bristol (Hybrid, 3 days onsite) SC Cleared or SC Clearable – hiring for multiple levels

Key Areas of Responsibility

As a Full Stack Developer, these are some of the core areas you’ll be working in:

• 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

We are looking for someone who is passionate about technology and who actively invests in their technical skills. You’ll be constantly learning in this role, but some key skills and experience you should already have include:

Essential

• 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.
• Must hold or be eligible for SC clearance. Candidates without existing clearance will be considered provided they meet the eligibility criteria.

Desirable (not essential)

• 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.
