Job Description

This role is responsible for validating ETL pipelines and data platforms built on Azure Data Factory, Databricks, and Microsoft Fabric, along with the downstream tables, reports, and models they feed.

KEY RESPONSIBILITIES Design and execute test plans covering source-to-target validation and transformation logic for ETL pipelines Write SQL and PySpark scripts to verify accuracy, completeness, and consistency in Delta Lake tables Perform regression testing on every pipeline change; a successful pipeline run does not guarantee correct output, and validation must be independent of execution status Build and maintain reusable data quality checks (e.g., Great Expectations,



dbt tests, or custom PySpark frameworks) in place of one-off manual queries Reconcile data between source systems and target Lakehouse/Warehouse layers, and investigate root cause when discrepancies are found Validate schema conformance, null/duplicate handling, referential integrity, and business rule adherence across Bronze/Silver/Gold layers Validate Microsoft Fabric artifacts — Lakehouses, Warehouses, and semantic models — including DirectLake mode behavior and cross-domain data consistency Apply consistent QA methodology across tools; the underlying platform (Databricks, Fabric, or otherwise) should not change how rigorously data is validated Document test cases and defects with enough detail for engineers to act on them without requiring additional clarification Work directly with the data engineering team on requirement clarification and defect resolution REQUIRED SKILLS Solid SQL, with th
