You will work closely with Tableau Developers and Data Engineers to validate dashboard functionality, performance, and underlying data integrity.

• Develop, execute, and maintain comprehensive test cases and scripts for functional, regression, and data validation testing of Tableau dashboards.
• Use intermediate‑level SQL to validate data accuracy, transformations, joins, aggregations, and KPI calculations between source systems and Tableau outputs.
• Perform end‑to‑end dashboard testing, including filters, parameters, calculations, drill down behavior, and performance validation.
• Design and implement automated testing workflows for Tableau dashboards using tools such as Wiisdom, Selenium, or similar automation frameworks.
• Document test strategies, test plans, defects, and release progress using JIRA, Confluence, Excel, and other reporting tools.
• Collaborate with Tableau Engineers and Data Engineers to clarify requirements, identify data issues, and ensure high‑quality dashboard releases.

• Bachelor’s degree or higher in Computer Science, Data Science, Information Systems, or a related field
• 5+ years of experience in dashboard or BI testing (Tableau strongly preferred)

• Solid understanding of database technologies (e.g., Redshift, Oracle, or similar)
• Strong analytical thinking and attention to detail
• Excellent communication skills and ability to work in a collaborative team environment.
• This is a PURELY TECHNICAL, HANDS-ON ROLE — not a coordination or oversight only position
• Candidate must be comfortable working directly with SQL queries, dashboards, and testing tools daily
• Local candidates only
• Must be able to work on‑site in Basking Ridge, NJ 2–3 days per week
