Software Developer

Our client is a well-established technology consultancy delivering mission-critical solutions at the very heart of UK National Security. They operate in some of the most secure and technically demanding environments in the country, and the bar for who they bring in is understandably high. This is a close-knit technical team working on complex, high-stakes software programmes where quality and reliability are non-negotiable. You'll be working alongside experienced engineers and technical leads, contributing directly to solutions that have real-world impact in a fast-paced, secure setting. What they absolutely need from you: proven commercial software development experience, a strong programming background, and the ability to deliver across the full SDLC, from design through to deployment. If you're a Senior Developer, the ability to guide others and contribute to technical decisions will set you apart. Sound like you?
