About the Role
We are hiring for Senior Software Developers in Test (React/Java) to join a growing Solutions Engineering team, supporting a large-scale modernisation and AI-enabled transformation programme.

Working within a greenfield approach inside a brownfield environment, you will introduce modern tooling, improve developer feedback loops, and embed quality earlier in the software delivery lifecycle.
You will report into a Principal Software Engineer and act as a senior quality engineering voice within delivery teams.
