• Lead and contribute to the migration of legacy ETL workloads to modern frameworks (e.g. Spark )
• Build and optimize large-scale batch and distributed data processing pipelines
• Analyze ETL performance (CPU, memory, I/O, runtime bottlenecks) and implement tuning strategies
• Develop reusable ETL frameworks, components, and orchestration patterns for enterprise use
• Implement data ingestion, transformation, and data quality checks across structured and semi-structured data sources
• Develop and maintain complex SQL transformations, stored procedures, and data models
• Integrate ETL pipelines with enterprise systems using messaging (Kafka/MQ), APIs, and batch orchestration frameworks
• Ensure data integrity, lineage, reconciliation, and auditability across pipelines
• Collaborate with architecture and engineering teams to design target-state data platforms and migration approaches
• Participate in end-to-end system integration and migration testing across distributed platforms
• Contribute to technical design discussions and provide input to stakeholders
• Collaborate with cross-functional teams including data engineering, application support, database, and infrastructure teams
• Mentor junior developers and promote best practices in ETL design, performance tuning, and data engineering
• Ensure adherence to coding standards, version control, and CI/CD practices (Git-based repositories)
