What You'll Do

• Build and operate the weekly AWS pipeline using Step Functions, Lambda and Fargate, with supplier-level fan-out over Aurora PostgreSQL and billions of linkage rows.

• Ensure data correctness through idempotent synchronization, prevention of silent data loss and reconciliation against the source system and legacy Oracle output.
• Investigate production failures to confirmed root causes, including timeouts, deadlocks, capacity limits and unusual supplier data, then implement the fix, improved logging and a regression test.
• Measure AI predictions against human decisions using ground truth, abstention handling and analysis of inconsistent verdicts.
• Maintain the React and TypeScript review application used by specialists to download, review and upload evaluations.
• Manage infrastructure as code with AWS CDK in Python and maintain CI/CD across sandbox, development and production environments in Azure DevOps.
