Tester - Big Data

Key Responsibilities:

• Partner with Data Engineers, Analysts, and business stakeholders to define quality requirements.
• Document test cases, data validation rules, and best practices for scalable data governance.
• Develop and implement test cases for ETL/ELT pipelines, data transformation, and ingestion processes.

• Validate data transformations and ingestion processes for structured and unstructured data.
• Monitor and troubleshoot data issues, failures, and inconsistencies across the pipeline.
• Provide support for root cause analysis and resolution of data-related defects, including the identification of code changes.
• Document and track defects, providing detailed reports to development teams for resolution.
• Participate in the design and implementation of automated testing scripts to improve testing efficiency.
• Conduct regression testing to ensure that new code changes do not adversely affect existing functionality.
• Perform post-release and post-implementation validation of software performance in production environments.
• Continuously monitor and evaluate the quality of software deliverables, providing feedback for improvement opportunities.
• Collaborate with end users to gather feedback.
