• Implement ETL/ELT processes supporting multi source, multi format data migration.
• Develop data models, schemas, mapping artifacts, and integration structures for legacy to cloud migration.
• Enhance automation, performance tuning, throughput, and fault tolerance within cloud based pipelines.

Data Quality, Transformation & Validation

• Lead data cleansing, normalization, enrichment, and validation efforts across legacy sources.
• Perform root cause analysis on data anomalies and guide corrective actions.
• Coordinate with QA/Test Engineers to embed data validation and automated testing into pipeline workflows.

Cloud Integration & System Support

• Support data engineering activities within AWS cloud environments (preferred).
• Collaborate with Cloud Engineers, DevSecOps teams, Migration Engineers, and system developers to integrate data flows with program architecture.
• Ensure compliance with security, logging, auditing, and handling requirements across environments.
