• Ensure processes, governance, and procedures are rigorously adhered to.

What you’ll need:

• Expert-level experience of performance monitoring and optimisation of Db2, including SQL tuning, buffer pool tuning, with the ability to make targeted recommendations to improve service stability and availability.
• Expert-level experience of governing and approving DDL changes, handling schema evolution, validating impact, and ensuring alignment to change‑control processes.
• Extensive experience of leading the resolution and troubleshooting of critical on-line systems.
• Proven experience of communicating and translating complex technical concepts for Senior Leadership.
• Experience of supporting junior team members, providing coaching on Db2 fundamentals, performance tuning, utilities, and operational processes.

It would be great if you also had:

• 10+ years of experience as a z/OS Db2 DBA in a financial organisation.
