Cittabase is Hiring hiring a Sr. QE Engineer for a large-scale Data & Analytics program spanning multiple source applications, a cloud data warehouse, and BI reporting tools. This role requires solid Data Warehouse and Data Engineering fundamentals as the primary bar, write and optimize SQL against large datasets, and build validation/automation logic in Java and/or Python.
Core Responsibilities
- Own quality engineering for assigned areas of the data platform — covering data validation, transformation logic checks, BI-layer testing, and pipeline health across multiple source applications, the cloud data warehouse, and BI reporting tools
- Write and review complex SQL against large datasets — joins, set operations, aggregations, and layer-aware comparisons appropriate to each stage of the DW
- Build Java and/or Python utilities/scripts to support test automation, data validation, and pipeline checks — including designing reusable, maintainable logic and handling large datasets efficiently
- Understand and account for aggregation-grain differences across DW layers




- Extract and validate data from source applications without direct database access, using API-based or scripted extraction approaches
- Work with data transformation pipelines to understand transformation logic and trace data lineage across layers
- Support performance validation for data pipelines and BI dashboard load
- Collaborate with the automation team to integrate validation logic into the existing CI/CD pipeline — deep BDD/Cucumber authorship not required, but willingness to learn and work within an existing framework is expected
- Contribute to test case design, defect triage, and quality reporting for the assigned scope

Required Skills & Experience
Data Warehouse / Data Engineering:
- 5+ years hands-on experience with a cloud data warehouse or lakehouse platform
- Strong SQL — able to write non-trivial queries from scratch joins across large tables, set-difference logic, aggregation and grain r
