Sr Quality Analyst - ETL Tester

Purpose of Job:
As an ETL Tester, you will play a critical role in ensuring the accuracy, consistency, and reliability of data as it moves through our ETL pipelines — from extraction and transformation through to loading into the data warehouse. You'll be responsible for designing test scenarios, executing source-to-target validations, and writing advanced SQL queries (joins, subqueries, window functions, aggregations) to catch data quality issues such as duplicates, nulls, and referential integrity gaps before they reach production. Working within an Agile team, you'll partner with data engineers, and business analysts to validate transformation logic and business rules, support UAT and production validation, and track defects through tools like Jira or Azure DevOps or GitHub. This role is ideal for someone with 3–5 years of ETL/DW testing experience who thrives on precision, enjoys solving data puzzles, and wants to grow into cloud, Big Data, or automation-driven testing.
