Your responsibilities

  • Design and implement data testing and quality assurance frameworks.
  • Build automated validation for data pipelines and data products.
  • Own source to target reconciliation between legacy systems and the new platform.
  • Build repeatable regression packs that run unattended.
  • Write unit tests that execute automatically within CI/CD, with quality gates that can block a release.
  • Detect and handle schema drift and unexpected structural changes.
  • Validate reports, dashboards, and semantic models, including measure definitions, filter behaviour, and totals.
  • Apply AI assisted techniques to test generation and coverage analysis, with human review.

Our requirements

  • 5+ years of experience in quality engineering, with meaningful recent experience testing data or ETL processes rather than applications.
  • Strong Python and SQL skills, used for building test automation rather than only running it.
  • Experience with pipeline validation, including row counts, control totals, referential integrity, and business rule assertions.
  • Experience with source to target reconciliation using defined tolerances.
  • Experience with test automation within CI/CD, including gates that block a release.
  • Experience with Azure DevOps.
  • Experience with SQL Server.
  • English proficiency at a level suitable for direct client conversations.

Optional

  • Experience with Azure Databricks or Microsoft Fabric.
  • Experience with data quality frameworks, including Great Expectations, dbt tests, Databricks Expectations, DLT quality rules, Soda, or Deequ.
  • Experience designing a test framework from scratch rather than extending an existing one.
  • Experience testing semantic models and BI layers.
  • Experience working in a regulated financial services environment.
  • Experience with application test automation alongside data testing, including Selenium, C#, SpecFlow, or Playwright.
