• Strong SQL and database knowledge (Oracle, SQL Server, MySQL)
• Familiarity with migration test tools (ETL Validator, Tx tools, Dextrus, Beyond Compare)
• Solid grasp of data governance, data quality, and remediation
• Ability to manage risks, resolve issues, and guide best practice in a fast-moving environment

This is a chance to roll up your sleeves, own the detail, and build something that will define how the bank delivers migrations going forward. If you want a role where you can make a real impact from day one, this is it.
