Work with data teams to understand source data, refresh schedules, ETL outputs, and data quality. Build workbooks following agreed technical standards and best practices. Optimize dashboard performance (extracts vs. live connections, calculations, filters, structure). Validate dashboard accuracy against source data and business rules. Support access controls, row-level security, publishing, and secure distribution. Assist with testing (unit, integration, UAT), defect fixes, and deployment. Write documentation, user guides, and knowledge-transfer materials. Requirements 2–4 years' experience in Tableau development, BI reporting, or data visualization/analytics.
