Data Test Engineer - Contract - 3 Months - Outside IR35
Key responsibilities
- Test and validate transformation and pipeline logic across Fabric, ADF, and Azure SQL stored procedures, functions, and views.
- Optimise SQL logic and pipelines for performance — reducing run time and resource use, without changing results.
- Build automated data-quality and reconciliation checks (record counts, referential integrity, aggregate totals, flag/measure consistency) that can be re-run to catch issues introduced by future changes.
- Test pipeline and database changes/migrations before they reach live environments.
- Record clear, reproducible findings for both defects and optimisation opportunities, and confirm changes with the development team.
