• Define and evolve the data architecture to support robust, secure, and scalable storage patterns across multiple AWS database services, especially as they relate to Payments and our ecosystem.
• Enforce and evolve data governance policies, including data classification, lineage, and access controls.
• Ensure compliance with industry standards and regulatory requirements for data privacy, integrity, and retention.
• Lead, manage, and mentor a small team of data engineers, promoting continuous learning, collaboration, and high performance.
