  • Experience working with messaging APIs (WhatsApp Business API, Apple Messages for Business, Twilio, etc.).
  • Familiarity with AI-assisted coding tools and comfort integrating LLM-powered features.
  • Strong background in RESTful and GraphQL API integrations, with proven success in completing end-to-end integrations.
  • Understanding of MCP (Model Context Protocol) and ability to implement custom integrations.

  • Excellent communication skills and ability to work in a fast-paced, collaborative environment.

  • Experience with AI agent frameworks (LangChain, AutoGPT, etc.).
  • Previous work building products at the intersection of AI and messaging apps.
  • Startup experience or comfort working in lean, rapidly changing environments.
  • Understanding of data security and compliance requirements for messaging apps.
