## Description

This role bridges data science and data architecture. The person will map data sources and relationships, build and maintain a company-wide data dictionary, and support the Enterprise Architect in applying policy, standards, and business logic to the overall data framework.

Key Responsibilities

 * Data Mapping

Identify, trace, and document how data flows across systems - from source to destination - including transformations, dependencies, and ownership.

 * Data Dictionary Development

Build and maintain a comprehensive data dictionary defining every field, its meaning, format, source, and business context, so teams have one consistent reference.

 * Architecture Support

Work closely with the Enterprise Architect to translate data mapping and dictionary findings into the technical architecture, ensuring data models reflect real business logic and policy requirements.

 * Data Quality & Standards

Analyze data for consistency, accuracy, and completeness. Flag gaps or conflicts between systems and recommend standardization.

 * Business Logic Validation

Partner with business stakeholders (HR, Finance, Operations, etc.) to confirm that documented business rules match how data is actually defined and used.

 * Governance Collaboration

Support data governance efforts by aligning the data dictionary and mapping work with company policy, compliance needs, and access control requirements.

 * Documentation & Reporting

Create clear, maintainable documentation (data lineage diagrams, dictionary entries, mapping reports) that both technical and non-technical teams can use.
