• Write, tune, and maintain SQL queries across multiple data sources (Data Lake, Redshift, SQL Server, Athena)
• Combine and reshape data using cross-database joins and data blending to support reporting needs
• Maintain and evolve reporting datasets ensuring data stays accurate, current, and well-structured for downstream use
• Focus on user-friendly, intuitive dashboard design and interface development
• Troubleshoot and resolve data or report-level issues
• Document report logic, data sources, and SQL transformations for maintainability
• Contribute to a standard visualization style guide and reporting best practices
• Develop Python scripts as needed for report automation (e.g., exporting dashboards as PDF/CSV)
• Integrate Tableau reports with APIs or other tools (R, Python) for predictive/real-time reporting
• Collaborate with AWS-based data teams (S3, Glue, Lambda) to source and prep report data
• Apply agentic engineering practices and AI coding tools (e.g., Claude, Copilot) to accelerate SQL development, report building, testing, and documentation
• Use AI-assisted workflows to automate repetitive data-prep, QA, and refresh-scheduling tasks

• 5 10+ years of experience, with strong emphasis on SQL and Tableau report/dashboard development
• Proven experience building reporting applications in a professional environment
• Solid understanding of data modeling and relational/columnar databases

• Comfortable using AI tools (e.g., Claude, ChatGPT, Copilot) and agentic engineering workflows to speed up development, testing, and documentation

Additional Skills

• Strong analytical thinking and structured problem-solving ability
• Comfortable contributing to migration of existing Tableau reports to Tableau Online, from a report-development standpoint
