Data & Functional Validation

• Validate end-to-end data flows from source systems (SAP/ODP, CTRM, pricing) into Aurora/PostgreSQL.
• Perform data validation and reconciliation to ensure accuracy, completeness, and consistency.
• Support validation of risk outputs (positions, exposures, pricing, P&L) against defined business logic
  
  

Pipeline & Ingestion Testing

• Test ETL/ELT pipelines for correctness, data integrity, and consistency.
• Validate snapshot and delta ingestion processes, including CDC scenarios.
• Verify handling of edge cases such as data ordering, duplication (idempotency), and recovery.
  
  

Test Automation & Execution

• Develop and maintain test cases and automated test scripts for data pipelines and SQL transformations.
• Execute functional, regression, and integration testing across data and reporting layers.
• Contribute to test automation frameworks using Python or similar tools.
  
  

Performance & EOD Validation

• Identify data discrepancies and performance issues during peak processing.
  

Defect Management & Collaboration

• Log, track, and support resolution of defects and data issues.
• Work closely with engineers and analysts to analyze root causes and validate fixes.
• Participate in test planning, sprint activities, and release validation.

Qualifications
