Required Skills
  • 4+ years of backend development experience, with strong programming skills (Python, Node.js).
  • Deep experience with serverless architectures, microservices, and AWS (Lambda, EC2, RDS).
  • Familiarity with LangGraph, LangChain, or equivalent AI orchestration frameworks.
  • Working knowledge of vector databases (Chroma, Pinecone) and semantic search.
  • Solid database and API design expertise, particularly with PostgreSQL.
  • Experience building scalable, low-latency backend systems for AI or data platforms.
