Data Modeler

A Data Modeler specializing in erwin for retail banking serves as a critical architect for the financial institution’s data landscape, responsible for designing, developing, and maintaining complex models that support core functions like CRM, AML, loan origination, and credit card processing. Leveraging deep technical expertise in erwin Data Modeler and erwin Mart, this professional translates intricate business requirements from risk, finance, and product teams into conceptual, logical, and physical structures that ensure high-performance transaction processing and robust data integrity. Beyond technical design, the role is heavily anchored in industry-specific compliance; the modeler must integrate data standards like BIAN or ISO 20022 and ensure that all structures adhere to stringent regulatory frameworks such as Basel III, BCBS 239, and GDPR. By managing metadata, establishing clear data lineage from teller systems to analytics platforms, and employing forward and reverse engineering for legacy modernization, they ensure that the bank’s data assets are transparent, governed, and optimized for both daily operations and complex financial reporting.
