Snowflake QA

Seeking a Data QA Engineer II to join the Data Engineering team supporting RIDW, our enterprise Snowflake data platform. This is a net-new headcount created to meet the growing quality and validation demands of the platform as we scale toward the DWEB Enterprise BI Go-Live and beyond.
In this role, you will own the design and execution of automated data quality frameworks, validate ETL and SCD pipeline behavior across our Bronze-Silver-Gold medallion architecture, and serve as the primary quality gate for data delivered to Power BI reporting and downstream business consumers. You will work closely with data engineers, the Data Engineering manager, and business stakeholders to ensure data accuracy, reliability, and observability across all platform layers.
Pipeline & ETL QA
• Design and execute test plans for Snowflake stored procedures, Task DAGs, and incremental/full-load pipeline patterns
• Validate SCD Type 1 and Type 2 logic, including active record counts, reactivation paths, and tenant code update behavior
• Test bronze ingestion across various data sources.
• Perform row count reconciliation, duplicate detection, and watermark/freshness validation across environment tiers (DEV, QA, UAT, PROD)
• Own regression testing during environment refreshes and schema promotion cycles
Data Quality & Validation
• Build and maintain data quality rules and threshold definitions.
• Validate Gold layer semantic models including rule view aggregations, Dynamic Tables, and reporting views
• Identify and document data anomalies, surface them via structured QA handoff packages, and track remediation through to sign-off
• Verify referential integrity across key grain tables.
• Conduct UAT validation cycles in coordination with business stakeholders and the BI team
Automation & Framework Build
• Develop automated test suites using Python, dbt tests, or Snowflake-native SQL to reduce manual regression effort
• Integrate QA checks into CI/CD pipelines via Azure DevOps, including pre-merge and post-deploy validations
• Build and maintain data observability tooling: zero-row load alerts, data freshness checks, watermark stall detection, and anomaly notifications
• Author reusable QA scripts and test fixtures that can be deployed consistently across DEV/QA/UAT environments
• Contribute to promotion tracking and CI/CD logging patterns that connect deployment events to quality outcomes
