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

About the Team

OpenAI's Industrial Compute organization is responsible for planning, delivering, operating, and optimizing the compute infrastructure that powers frontier AI.

As OpenAI scales toward becoming an intelligence utility, Industrial Compute coordinates a complex lifecycle spanning infrastructure strategy, capacity planning, provider partnerships, fleet operations, product demand, and financial planning. The organization manages one of the largest and fastest-growing compute footprints in the world, where decisions around capacity allocation, deployment readiness, utilization, reliability, and product demand directly impact product availability, customer experience, and business performance.

The Capacity Systems team builds the software platforms, data systems, and automation frameworks that connect these functions into a shared operating model. We transform fragmented planning workflows into scalable systems that enable teams to understand what compute was contracted, delivered, healthy, allocated, and ultimately converted into business and research outcomes.

About the Role

We are seeking a Capacity Systems Software Engineer to build the platforms and services that power Industrial Compute planning, forecasting, optimization, and operational decision-making.

In this role, you will design and develop software systems that connect infrastructure delivery, fleet health, capacity allocation, demand forecasting, deployment readiness, financial planning, and product consumption into a unified system of record. Your work will help OpenAI make better decisions about where compute should be deployed, how capacity should be allocated, and how infrastructure investments translate into business value.

You will partner closely with Capacity Planning, Fleet Operations, Infrastructure Engineering, Product, Finance, Supply Chain, and Strategic Sourcing teams to replace spreadsheet-driven workflows with scalable software systems that enable visibility, automation, and decision support across OpenAI's global compute footprint.

This role is ideal for engineers who enjoy building internal platforms, operational systems, workflow automation, and data-intensive applications that sit at the intersection of software, infrastructure, and business operations.

Why This Role Matters

Demand for compute is growing faster than traditional planning systems can support.

Capacity decisions increasingly require understanding complex tradeoffs across infrastructure delivery, fleet health, model deployment, latency, utilization, cost, revenue impact, and operational risk. The systems built by this team help transform compute from a collection of disconnected operational signals into a measurable, optimizable business capability.

Success in this role will help create a world where every major unit of compute can be traced from infrastructure commitment through delivered business value, enabling faster launches, higher utilization, improved operational efficiency, and better decision-making across OpenAI.
