• Hands-on experience building cloud data solutions on AWS using AWS Glue, Step Functions, Lambda, Athena, S3, and EC2.
• Proficiency in Python and/or PySpark for data processing, automation, and integration.
• Experience ingesting data from relational databases, files, APIs, and other enterprise sources into governed cloud data layers.
• Experience working with reusable ingestion or hydration frameworks and configurable, metadata-driven pipeline patterns.
• Ability to build curated data products from source-aligned data, including transformation, validation, reconciliation, and publication for consumers.
• Knowledge of data quality, metadata, lineage, security, encryption, identity and access management, monitoring, and audit controls.
• Experience with Git-based source control, automated testing, CI/CD, and deployment across development, test, and production environments.
