Senior Full Stack Developer

Senior Software Engineer (Full Stack – Systems Ownership)

Defence & National Security | UK Wide | Up to £100,000 + Package

Most “full stack” roles mean building features.

This one means owning systems.

We’re working with a well-funded Defence AI business building secure, large-scale software platforms used across Defence, National Security and Government environments.

They’re hiring Senior Software Engineers who can take end-to-end ownership of complex systems — not just front-end or backend slices.

What you’ll actually be doing

• Designing and building full-stack platforms from the ground up
• Owning backend services, APIs, and system architecture
• Developing modern web applications (React / TypeScript)
• Working with cloud-native infrastructure (AWS / Azure)
• Integrating AI and data capabilities into real systems
• Deploying software into secure, operational environments

What they’re looking for

• Strong experience in C# / .NET, Java or Python
• Frontend experience (React + TypeScript)
• Backend / API / distributed systems experience
• Cloud experience (AWS or Azure preferred)
• Engineers who think in systems, not tickets
• Defence, National Security or consultancy background highly desirable

Why this role stands out

This is not a “feature factory” environment.

You’ll be joining a high-growth, well-funded Defence AI business where engineers are trusted to design, build and own real systems used in critical environments.

Startup pace. Defence-grade impact. Real ownership.

Package

• Up to £100,000 + benefits
• UK Wide
• Defence & National Security programmes
• High-impact, complex engineering work

If you want to build systems end-to-end — not just components — this is worth a conversation.
