  • Monitor/evaluate agent performance with LangSmith, AgentOps, and similar tools.
  • Ship real-world enterprise AI use cases - Copilots, orchestration engines, intelligent search, and more.
  • Mentor and review the work of junior AI engineers, spreading best practices.
  • Work with product, data, and DevOps teams to bring AI solutions into production at scale.

What Youll Bring

  • Proven track record with RAG pipelines and vector databases.
  • Hands-on with agent frameworks (LangChain, LlamaIndex, etc.) and orchestration.

  • Delivered enterprise-grade AI solutions (not just demos).
  • Experience mentoring engineers and building technical excellence in a team.
