  • Generate AI-assisted validation reports that explain detected issues in clear, actionable terms.
  • Integrate AI validation capabilities into AWS data platforms and workflows (Glue, Lambda, Redshift, Athena, S3).
  • Evaluate how AI can be used to deliver in-depth QA analysis of deliverables.
  • Collaborate with data engineering, QA, and business teams to define data quality rules, thresholds, and SLAs.
  • AI-powered data validation platform.
  • Automated ETL quality control framework.
  • Anomaly detection models and monitoring dashboards.

  • Hands-on experience with AWS Lambda, AWS Glue, Amazon Redshift, Amazon Athena, and Amazon S3.
  • Practical experience with machine learning and anomaly detection techniques applied to data (statistical, time-series, or ML-based).
  • Solid understanding of data quality and data governance principles (completeness, accuracy, consistency, lineage).
  • Experience designing source-to-target reconciliation and ETL testing strategies.
  • Solid understanding of Agile, SDLC, and modern engineering best practices.

Desired or nice to have expertise _

  • Experience with data quality frameworks such as AWS Glue Data Quality, Great Expectations, or Deequ.
  • Experience building monitoring dashboards (Amazon QuickSight, CloudWatch, or similar).
  • Familiarity with Amazon SageMaker or other ML platforms for model training and deployment.
