Reference Data Management -Data Analyst

About the job

The Reference Data Management (RDM) capability is a foundational pillar of Sanofi's commercial data ecosystem, designed to deliver clean, governed, and AI-ready reference data and codelists at enterprise scale.

RDM manages 200+ commercial codelists spanning 50 countries, providing the standardized definitions, mappings, hierarchies, and classifications that underpin downstream analytics, AI models, and business intelligence across the commercial organization. These codelists - covering domains such as markets, products, customers, hierarchies, and organizational structures - serve as the single source of truth for commercial reference data, ensuring consistency, accuracy, and compliance across global markets.

The capability integrates tightly with Sanofi's Snowflake-based data platform, where RDM data is consumed by 50+ downstream systems, data shares, and AI/analytics applications. A key architectural principle is that clean, governed codelists are the foundation for AI/analytics consumption - without accurate, well-structured reference data, AI models and business insights cannot be trusted or scaled.

RDM is built on the Informatica MDM platform and follows enterprise data governance standards, ensuring that all reference data changes are properly assessed, approved, validated, and documented. The capability is governed by a cross-functional team including the RDM Platform Product Owner, Data Owners, Data Stewards, and Platform/System teams, and is sponsored by the Global Head of GTMC Data Management and Head of Global Commercial Data Foundations.

As Sanofi scales its AI-powered commercial capabilities, RDM plays a critical role in enabling trusted, reusable, and interoperable data - reducing duplication, maximizing data quality, and accelerating time-to-insight for business stakeholders worldwide.
