• Design, develop, test, and publish interactive dashboards, workbooks, and reusable data sources in Tableau.
• Use SQL to prepare and validate data, reconcile dashboard results against source systems, and investigate discrepancies.
• Optimize dashboard load times and responsiveness by reviewing workbook design, calculations, queries, and extract usage.
• Maintain published content in Tableau Server or Tableau Cloud, troubleshoot refresh failures, and coordinate access and permissions with platform administrators.
• Document metric definitions, data sources, and workbook logic so others can use and maintain the reporting.
• Gather feedback from dashboard users and refine reports as business needs evolve.

• Strong SQL skills, including joins, aggregations, common table expressions, and window functions.
• Working knowledge of relational data modeling, including how data grain and join cardinality affect reporting accuracy.
• Experience with Tableau Server or Tableau Cloud, including publishing workflows, extract refreshes, and content permissions.
• Ability to apply data visualization principles to make complex information easy to interpret and act on.
• Ability to clarify ambiguous requirements, explain technical decisions to non-technical audiences, and collaborate across teams.
