This role will focus heavily on developing and maintaining SQL-based transformation logic to ensure high quality, trusted, and analytics ready data.
Working closely with the Data Management team, the Data Engineer will help identify, remediate, and prevent data quality issues by encoding validation rules and controls directly into data pipelines.

Partner closely with data analytics and reporting teams to understand consumption needs and ensure data is structured for performance, usability, and scalability.

Implement and enforce data quality rules, validation checks, and automated error detection within ETL and transformation workflows.

Support master and reference data processes, including defining data quality criteria, uniqueness rules, and remediation approaches.
-
Collaborate with domain owners and data stewards to analyze root causes of data quality issues and drive corrective actions.
-
Monitor cross-domain data provisioning to ensure data is sourced from approved and governed systems.
-
Contribute to the evaluation and implementation of data governance, architecture, and quality tools in partnership with Global Technology teams.
-
Document data pipelines, transformation logic, and architectural decisions to support maintainability and knowledge sharing.
