As a Principal / Lead Data Engineer with a focus on finance and SAP-related data, you will be responsible for the design, development, and evolution of our finance data platform. You will build reliable data architectures, ensure accurate reconciliation between source systems and the data lake, and support high-quality financial reporting.
