Develop dbt-native tests as well as custom Python unit tests to validate transformation correctness and data quality.
Develop Airflow DAGs to orchestrate Python EL and dbt scripts end-to-end, producing output that is functionally equivalent to the source Informatica workflows.
Contribute to GitLab CI/CD pipeline for dbt and Airflow code, including lint gates, automated testing, and deployment to shared NAS.
Perform peer code reviews and provide constructive technical feedback to fellow engineers.
Troubleshoot performance issues and data discrepancies during SIT and UAT, including row-count reconciliation between source Oracle/SQL Server systems and the target warehouse.
Contribute to technical documentation, runbooks, and handover materials.
