• Build test harnesses and reusable libraries for unit, integration, and regression testing of ETL pipelines and APIs.
• Implement continuous testing pipelines integrated with CI/CD tools (Azure DevOps, GitHub Actions, or Jenkins).
• Collaborate with data engineers to embed data quality gates within orchestration tools (Azure Data Factory / Airflow).
• Define and monitor data quality KPIs, thresholds, and alerting using observability tools (Datadog, Prometheus, etc.).
• Develop mock data generation and simulation frameworks for performance and stress testing.
• Ensure comprehensive test coverage for schema evolution, transformation logic, and downstream data consumption APIs.
• Contribute to best practices and documentation around test-driven data engineering and quality-first development culture.
