You will lead a QE team building a cross-platform BI Test Automation Framework in Python and Playwright that validates enterprise dashboards on Tableau, Power BI, and Looker. The core of the role is engineering test cases that are written once and run against all three platforms through a shared, tool-agnostic Python layer, covering data accuracy against BigQuery and source systems, filters and interactions, row-level security, visual rendering, and dashboard performance.
Key Responsibilities
• Strategy & Leadership: Own the BI QE strategy across functional, data, security, visual regression, and performance testing for Tableau, Power BI, and Looker; lead a team of QE engineers, set coding standards, review pull requests, and provide sprint-level quality sign-off.
• Reusable Framework Architecture: Design and own a platform-agnostic Python framework in which a single test case runs against Tableau, Power BI, and Looker. Use an adapter / Page Object pattern with a common BI interface (open dashboard, apply filter, set parameter, drill down, read KPI / table values, export data),



with one adapter implementation per platform, so that recent dashboards and platforms plug in without rewriting tests.
• Playwright Automation: Build robust UI automation with Playwright for Python, handling embedded iframes, shadow DOM, canvas / SVG-rendered visuals, lazy-loaded tiles, and asynchronous query rendering, using reliable locator strategies, explicit wait conditions, and network interception rather than fixed sleeps.
• Test Authoring & Data-Driven Design: Author test cases with pytest (fixtures, parametrisation, markers, plugins), optionally with pytest-bdd / Gherkin for business-readable scenarios; externalise dashboards, filters, expected KPIs, and user roles into YAML / JSON / CSV test data so the same suite scales across reports, environments, and platforms.
• BI Data Validation: Reconcile values shown on dashboards (KPIs, crosstabs, aggregations, totals, filtered views) against
