Own the reliability, quality, and timely delivery of data lake platform services supporting Santander UK workloads.
Collaborate closely with data engineering, security, and platform teams to enable effective end‑to‑end delivery across the data lake ecosystem and minimise friction between infrastructure and application layers.
Partner with enterprise and data architecture to ensure cloud infrastructure, shared services, and data lake applications conform to approved group architectures and engineering standards.
Develop a great understanding of how the data lake platform supports customer journeys and financial data flows, ensuring infrastructure and services are secure, resilient, and fit for purpose.
