About the Role

We’re hiring a developer with deep, hands-on experience building with MCP and ChatGPT Apps. This is not a general AI role. You should already be comfortable working inside these ecosystems, even if that experience comes from building, testing, or experimenting with your own projects.

  • Rapidly prototype and test new ideas using MCP and ChatGPT environments
  • Use Claude Code as part of your development workflow
  • Improve performance, reliability, and usability of AI-driven features
  • Collaborate on product direction and technical architecture
What We’re Looking For
  • Someone who has already spent serious time inside MCP + ChatGPT App environments
  • Builders who experiment, ship quickly, and learn by doing
  • Developers who understand both the technical and product side of AI apps
  • People who can operate with high ownership and minimal oversight
  • Extensive experience working with MCP Apps and ChatGPT Apps
    • This can include production work, side projects, or heavy experimentation
    • You should not be learning these for the first time in this role
  • Strong proficiency in JavaScript (React) or TypeScript (Node.js preferred)
  • Experience integrating and working with LLM APIs (OpenAI, Anthropic, etc.)
  • Working knowledge of Claude Code and how to use it effectively in development workflows
  • Experience building and shipping full-stack applications
  • Strong understanding of prompt design, tool usage, and AI interaction patterns
  • Retirement Plan (401k, IRA)
  • Paid Time Off (Vacation, Sick & Public Holidays)
  • Free Food & Snacks
  • Wellness Resources
  • Stock Option Plan
