• Experience working within regulated environments or financial services programmes.

NICE TO HAVE

• Understanding of Data Mesh or product-aligned data ownership models.
• Exposure to orchestration tools such as Airflow, Control-M or similar scheduling frameworks.
• Experience with data governance and metadata tooling such as Dataplex, Collibra or equivalent.
• Experience supporting migration from Legacy warehouse platforms to cloud-native data platforms.
