• Working knowledge of SQL (Snowflake preferred but SQL Server, Oracle, and Teradata are also relevant).
• Experience with analytical or data tools such as Python to analyze data, validate outputs, and resolve complex data issues; AI tool experience is a plus.
• Strong collaboration, communication, and organizational skills across business and technical teams.
• Experience contributing to automation or data quality improvement initiatives is a plus.

Job Contribution:

Recognized as an experienced professional with strong working knowledge in the field, this role independently handles moderately complex data issues, supports key data quality and operational initiatives, and contributes to improvements in enterprise data reliability and performance.
