About the role

Engineers to build the systems behind OpenAI's plugin ecosystem, focusing on APIs, SDKs, plugin discovery and usage experiences, and reliable execution across ChatGPT and Codex.

Responsibilities

  • Design and ship APIs, SDKs, and services that developers use to extend ChatGPT and Codex.
  • Build intuitive experiences that help users discover, install, and use plugins to get more done.
  • Make plugins easier to create, test, publish, update, and share.
  • Improve when and how models use plugins, from choosing the right plugin to completing a task. Work with Research to diagnose failures and measure improvements as models evolve.
  • Improve plugin reliability and interaction quality across ChatGPT and Codex, including interactive apps, with clear error messages and recovery paths.
  • Build consistent permissions, approvals, and admin controls that help individuals and organizations confidently adopt plugins.
  • Work with developers and partners to turn recurring problems into improvements to the platform, tooling, and documentation.
  • Collaborate across engineering, Product, Research, Security, and Trust & Safety to scale plugin infrastructure and deliver safe, reliable execution.

Qualifications

  • Care about product quality and can make complex capabilities feel intuitive, from discovering a useful plugin to completing a task with it.
  • Have strong opinions about APIs and abstractions, and can explain the tradeoffs behind your decisions. Experience with identity, permissions, or integration-heavy systems is especially valuable.
  • Enjoy talking with users and developers, understanding what they’re trying to accomplish, and turning recurring problems into product and platform improvements.
  • Can move between product questions and technical details, collaborate across teams, and take an ambiguous problem through to production.
  • Are comfortable working across web interfaces and backend systems. Experience building applied AI systems, diagnosing model–tool interactions, and measuring reliability and quality is especially valuable.
  • Have built products people rely on or software that other developers use, such as an API or SDK, an open-source project, a developer platform, or internal tools with real users.
