  • Validate Tableau dashboards and BI reports for data accuracy, performance, and visualization correctness.
  • Develop and execute complex SQL queries to ensure data integrity across multiple systems.
  • Conduct data reconciliation, profiling, and quality checks within data warehouse and reporting environments.
  • Collaborate with developers, data engineers, and business analysts to identify and resolve data quality issues.
  • Document test results, track defects, and provide clear QA metrics to stakeholders.
  • Support the automation of BI/ETL testing processes where feasible.

Qualifications

  • 3–8 years of experience in ETL, BI, or Data Warehouse testing.
  • Strong hands-on experience with ETL tools such as SSIS and IBM DataStage.
  • Proficient in working with Tableau BI dashboards and validating reports and data visualizations.
  • Expertise in SQL for data validation, reconciliation, and crafting complex queries.
  • Comprehensive understanding of data warehouse concepts, data modeling, and BI processes.
  • Experience testing source-to-target mappings (STTM) and transformation logic.
  • Strong communication and collaboration skills, especially in Agile/Scrum environments.
  • Relevant educational qualifications may include a degree in Computer Science or related fields.

Preferred Skills

  • Familiarity with additional BI tools (e.g., Power BI, Business Objects).
  • Experience in ETL/BI testing automation frameworks like QuerySurge, Informatica DVO, and Selenium + DB.
  • Knowledge of cloud-based data platforms such as Azure, AWS, or GCP.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
