As a Fabric & Power BI Data QA Engineer, you will ensure the end-to-end data accuracy, reliability, and visualization integrity of enterprise analytics solutions. You will collaborate with data engineers, BI developers, analysts, onsite/offshore teams, and business stakeholders to validate data transformation logic, data pipeline orchestration, semantic models, and executive reporting dashboards.

Work You'll Do :

- End-to-End Test Strategy & Planning : Review functional and technical specifications to create comprehensive test plans covering the entire data lifecycle - from source ingestion to final Power BI reporting.

- Fabric Pipeline & Data Layer Testing : Validate source-to-target data mappings, incremental loads, watermarking, schema drift handling, and business transformations across OneLake, Lakehouse (Delta tables), and Data Warehouse layers.

- Power BI & Semantic Model Validation : Thoroughly test Power BI reports and dashboards, validating semantic models, relationships, DAX calculations, filter contexts, KPIs, drill-throughs, and Row-Level Security (RLS).

- Automated & Script-Based Validation : Write and execute complex SQL queries and PySpark scripts within Fabric Notebooks to automate regression testing, aggregate checks, and cross-layer data reconciliation.

- Defect Management & Triage : Identify, document, log, and track data and visualization defects using Azure DevOps or Jira, working closely with engineering and BI teams for prompt resolution.

- Agile & Quality Governance : Actively participate in sprint planning, story refinement, and test estimation, driving QA standards and automated testing practices across the team.

- Verify data accuracy and pipeline orchestration across Fabric Data Pipelines, Dataflows Gen2, and PySpark Notebooks.

- Validate data persistence and consistency across OneLake, Lakehouse, and Data Warehouse architectures.

- Perform rigorous Power BI Testing :

1. Reconcile report and dashboard metrics directly against underlying Fabric Lakehouse / Warehouse gold tables and source systems.

2. Validate complex DAX measures, calculated columns, hierarchies, and dynamic aggregation logic.

3. Verify report performance, slicers, cross-filtering behaviors, drill-downs, and visual interactions.

4. Test and validate Row-Level Security (RLS) and user access permissions across different security roles.

- Develop automated data validation scripts using SQL and PySpark for regression testing and large-volume reconciliation.

- Test pipeline error-handling frameworks, retry mechanisms, and schema drift handling.

- Integrate test gates and automated quality checks into Azure DevOps / CI/CD deployment pipelines.

Qualifications :

Must-Have Skills / Project Experience :
