  • Conduct manual reviews of legal names, "doing business as" (DBA) names, and address details to confirm whether matched records represent the same business entity.
  • Establish and follow standardized verification and approval processes, manually approving or rejecting entity matches based on accuracy and supporting documentation.
  • Perform additional research using online resources and publicly available data to validate entities when automated matching is inconclusive.
  • Document all decisions related to entity confirmation to ensure full traceability, auditability, and support of data quality initiatives.
  • Provide insights and recommendations to improve automated matching logic and workflows based on recurring manual review findings.
• Master Data Quality Management
  • Regularly monitor master data for accuracy, completeness, consistency, and reliability, initiating corrective actions when data issues or inconsistencies arise.
  • Identify data quality gaps and work with business and technical teams to implement remediation plans and prevent recurring issues.
  • Ensure master data within the Customer domain remains accurate and aligned to business and regulatory requirements.
• Master Data Standards, Definitions & Governance
  • Establish and maintain data standards, definitions, and business rules for Customer master data elements, ensuring alignment with enterprise data governance policies.
  • Enforce data integrity rules, business rules, and compliance requirements—including financial, regulatory, and privacy standards.
  • Maintain oversight of the master data lifecycle (creation, updates, merging, archiving, and deletion) to ensure timely, accurate, and consistent data availability.
  • Document and maintain metadata, data lineage, and data stewardship artifacts to support consistency and governance across systems and processes.
• Stakeholder Collaboration & Operational MDM Support
  • Collaborate with business units, IT, compliance, and data governance teams to align on master data needs, integration requirements, and data quality expectations.
  • Serve as a key point of contact for business representatives needing clarification on Customer master data or related governance standards.

• Bachelor’s Degree in Business Administration, Computer Science, Information Management, Quantitative Analytics, Data Science, or a similar discipline.
• 6–8+ years of experience working in data stewardship, data governance, master data management, or a similar data‑focused role.
• Familiarity with data governance policies, data lifecycle management, and regulatory requirements impacting Customer data.
• Experience with MDM technologies such as Informatica MDM, Informatica Customer 360, Reltio, or similar master data platforms (preferred).
• Familiarity with data‑matching algorithms, survivorship rules, data quality concepts, and entity resolution processes.
• Strong understanding of Customer data structures, entity relationships, and master data workflows.
