About the Role

The Senior QA Engineer for Data will test and validate the data platform behind our internal back-office systems, including Databricks pipelines and the Power BI reports that business users rely on.

• Test and validate Power BI reports against source data.
• Define and implement data quality checks, and help set QA standards for the data platform.
• Integrate data tests into CI/CD pipelines.
• Investigate data defects and pipeline performance issues, and coordinate fixes with data engineering.
• Work with business users to understand how they use data and reports, and propose technical and non-technical solutions to business problems.
• Mentor onshore and nearshore QA testers, and review their test code against coding standards.
• Track and report on data quality metrics, test coverage, and release readiness.
• Stay current on QA tools and practices, including AI-assisted testing.
