We’re supporting a major defence software programme and are now looking for an experienced Software Engineer (C# / .NET) to provide short-term delivery support.

The project is in an active update and stabilisation phase and needs an engineer who can quickly get up to speed with an existing codebase.

This is an intial three month project – there is a strong likelihood of extension or movement onto a follow‑on project depending on programme need and performance.
