• Experience working in Azure or another major cloud environment.
• Good grasp of SQL Server, performance optimisation and data‑driven applications.

• Clear communication skills and a pragmatic delivery mindset.

• Work on a high‑impact payments platform with a respected Northern Ireland engineering team.
