  • (e.g., ADF, Glue, dbt, Informatica, Talend, Airflow etc.)

Responsibilities

  • Design, develop, and execute
    data-focused test plans and test cases
  • Validate ingestion, cleansing, transformation, and loading logic
  • Write and maintain SQL-based validation scripts
  • Detect discrepancies, anomalies, schema drift, and data inconsistencies
  • Collaborate with data engineers to troubleshoot and resolve issues
