  • Experience working on enterprise-grade, high-performance applications with complex data interactions.
  • Strong communication skills and ability to work with global distributed teams in US time zones.
  • Experience with PostgreSQL or Aurora PostgreSQL is preferred.
  • Experience modernizing from legacy databases such as Oracle, SQL Server, or DB2 is preferred.
  • Exposure to automated code-refactoring tools or GenAI-assisted remediation workflows is preferred.
