  • Experience building internal libraries, services, or APIs used across teams

Bonus

  • Experience with agent frameworks (LangChain, CrewAI, AutoGPT, etc.)
  • Exposure to evaluation tools and prompt optimization strategies
  • Prior experience designing tool schemas or function-calling workflow
