Build tech that matters.
This isn’t about shaving milliseconds off a checkout flow or tweaking ad algorithms. This is about designing and delivering software that protects lives, missions, and national infrastructure. You’ll be part of a trusted team working at the heart of UK National Security, solving complex problems with cutting-edge tools — and doing it fast.
We’re looking for curious, adaptable Full Stack Engineers who thrive on variety, love learning new tech “just in time,” and want to work on systems that genuinely make a difference.

2. Collaborating with users, researchers, and engineers to shape solutions from concept to deployment
3. Working in agile teams to deliver working software at pace
4. Translating ideas into clean, test-driven code that’s easy to maintain and open by default
5. Designing and integrating components across cloud, containerised, and on-prem environments
6. Helping shape strategy and tech direction in a fast-moving, mission-led environment

7. Languages: Python, Java, Golang, JavaScript, C++

9. Back End / Web:, Nginx, Caddy, Uvicorn
10. Databases: PostgreSQL, MySQL, MongoDB, Cassandra
11. Cloud & Containers: AWS, Azure, GCP, Docker, Kubernetes

14. Growth: Long-term programmes, modern tech stacks, and a culture of continuous learning.
15. Environment: Work from sustainable, well-equipped offices in Hampshire or Greater London, with on-site gyms, green spaces, and excellent transport links.
16. Culture: No corporate fluff — just smart people solving hard problems together.
