  • Deploy and operate workloads on AWS (ECS/EKS, EC2, Fargate, API Gateway, VPC, security patterns)
  • Integrate with internal/external systems using robust API patterns (retries, idempotency, rate limiting, circuit breakers)
  • Implement secure AuthN/AuthZ (OAuth2/OIDC, SAML, RBAC, secrets mgmt)
  • Enable governed access to Snowflake/warehouse environments and build data-driven features
  • Own CI/CD, testing, observability, performance, and production readiness


Qualifications

  • Recent hands-on experience building GenAI/Agentic AI solutions (LangChain/LangGraph, Bedrock, Snowflake Cortex, RAG)
  • Strong backend engineering in Python (FastAPI preferred)
  • Strong React front-end experience
