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.

• Implement KPI evaluations as independent API services, covering rule-based checks and AI/ML-assisted evaluations together with DQM specialists who own the rules.

• 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.

What We're Looking For

• 3+ years of professional Python backend development experience.

• Degree in Computer Science, Software Engineering or a comparable field, or equivalent professional experience.

• Vietnamese native speaker; fluent English, written and spoken. German is a plus.

• Ability to work independently while collaborating with local and international teams.

• Strong SQL and PostgreSQL skills, including performance tuning and database design.

• Experience with large-scale ETL/batch processing and reliable data pipelines.

• Hands-on experience with AWS (Step Functions, Lambda, Fargate, Aurora) and Infrastructure as Code (AWS CDK, Terraform, or CloudFormation).

• Solid knowledge of automated testing, Docker, CI/CD, monitoring, and production troubleshooting.

• Experience with React and TypeScript; familiarity with Module Federation, Vite, or Mantine is a plus.
