Job Description
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.
