What You'll DoYou'll own the quality of data as it moves through ETL pipelines in a state Medicaid environment - from reviewing requirements all the way through defect resolution, regression testing, and automation.
- Review Change Requests (CRs) and participate in requirement analysis for new EDW extracts and transformations.
- Participate in data modeling and requirement gathering sessions to ensure testing stays aligned with business needs.
- Perform backend testing to compare data in source systems to target Medicaid Enterprise Data Warehouses (EDW); verify source-to-target data mapping and transformation logic for Medicaid datasets.
- Validate data quality, standardization rules, and loading accuracy across full-load and incremental-load cycles.
- Write complex SQL queries - multi-table JOINs, aggregations, row counts, null checks, duplicate checks, and referential integrity validation - to validate ETL outputs against business rules.
- Design test plans, test cases, and test scenarios for ETL processes; execute both manual and automated tests.
- Identify, document, and track discrepancies using JIRA, HP ALM, or Azure DevOps Test Plans; collaborate with ETL developers to resolve defects and perform regression testing.
- Develop automated database validation scripts using Python, SQLAlchemy, and Pandas; create shell scripts for ETL monitoring and log analysis.
- Integrate test automation into CI/CD pipelines in Azure DevOps.
- Document test results and provide detailed, actionable feedback to stakeholders.
