QA Analyst, ETL Tester

Job Description: Youll 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.
