About the Team

The Plugin Developer Platform team builds the APIs, SDKs, and tools that let people extend ChatGPT and Codex. We work on plugins, connectors, the Model Context Protocol (MCP), and interactive apps.

About the Role

We're looking for platform-minded engineers who know what it takes to build a platform developers want to use. You'll work across developer-facing interfaces, APIs, and backend systems. You'll own features from the first developer conversation through implementation and release.

Responsibilities

  • Design and ship APIs, SDKs, and services that developers use to extend ChatGPT and Codex.
  • Make plugins easier to create, test, publish, update, and share.
  • Improve compatibility and consistency across ChatGPT and Codex, including interactive app experiences.
  • Contribute to MCP and other open standards, bringing practical developer needs into their design.
  • Work with developers and partners to understand recurring problems and improve the platform, tooling, and documentation.
  • Work with Product, Research, Security, and Trust & Safety on permissions, compatibility, and safe, reliable execution.

Requirements

  • Have built software that other developers use. Your experience might include an open-source project, an API or SDK, a developer platform, internal tools with real users, or a devtools company.
  • Have opinions about APIs and abstractions, and can explain the tradeoffs behind your decisions.
  • Enjoy talking with developers and learning what they are trying to build.
  • Can move between product questions and technical details, identify what matters, and take work from an unclear problem through to production.
  • Are comfortable working across web interfaces and backend systems, and learning unfamiliar parts of the stack.
  • Want to help define how developers build software for AI agents, including through open standards such as MCP.
