About the Team

Our team brings OpenAI's most capable technology to the world through our developer platform: the OpenAI API. As the leading AI development platform, our API is used by millions of developers and the majority of enterprises around the world, and powers the majority of AI applications that you may use on a daily basis. The platform supports everything from simple model calls to stateful, multimodal, tool-using applications through the Responses API, Agents SDK, Realtime API, and more. Our SDKs turn that fast-moving platform into reliable, idiomatic developer experiences across languages.

About the Role

We are looking for a software engineer to help build the official SDKs that power the OpenAI API. Currently offered in Python, Node.js, Golang, Java, and Ruby – our SDKs are some of the most popular in the world. You will help shape the developer experience for all new API features, as well as all future versions of our APIs. We're looking for engineers who are deeply immersed in AI-native development: people who actively build with Codex and other coding agents, have developed agentic applications or developer tools, and bring strong, experience-backed opinions about OpenAI's APIs. You'll pair that firsthand product intuition with meticulous SDK design to improve how developers build with our platform. Prior experience building SDKs is lovely, but not absolutely necessary.

In this role, you will:

Define and implement the SDK experience for all new API features, as well as all future versions of our API.
Build and experiment with agentic applications, developer tools, and coding-agent workflows using Codex and OpenAI's APIs, translating firsthand experience into better SDK abstractions, API ergonomics, and developer experiences.
Build and maintain our systems to make SDK maintenance and generation streamlined and automated.
Contribute to our SDK strategy and roadmap, including which languages to support and what features to support.
Collaborate closely with the rest of the API team, our Developer Experience team, and our GTM team to make our SDKs the best in the world.
Work directly with developers adding features, fixing issues, and contributing to documentation.

You might thrive in this role if you:

7+ years of professional engineering experience (excluding internships) in relevant roles at tech and product-driven companies.
Have deep, hands-on experience using Codex and other coding agents to build and ship software.
Have built agentic tools or AI-powered systems and understand practical considerations such as tool use, orchestration, evaluation, and reliability.
Have built directly with OpenAI's APIs and SDKs and can articulate specific opinions about their strengths, limitations, and opportunities for improvement.
Love building for other developers, and thrive on feedback from opinionated users.
Thrive working in the open source community, and love engaging directly with developers.
Can thrive and operate independently in a fast-paced environment with ambiguous requirements and goals.
Are an engineer at heart, but are willing to lean into product decisions.
Have experience maintaining SDKs or building SDK-generation software.

Compensation Range: $293K - $385K USD
