Job Description
About the Team
The ChatGPT Ecosystem team is a core part of our broader effort to evolve ChatGPT into a true super-assistant.
Our goal is to build the platform that allows developers—and eventually end users—to extend ChatGPT in powerful ways, making it dramatically more useful across a wide range of real-world tasks. We’re creating the foundation for a rich ecosystem of applications, integrations, and tools that expand what ChatGPT can do.
This team sits at the intersection of product engineering, platform design, and developer experience, working closely with product, research, security, and trust & safety to enable a global community of builders to create on top of ChatGPT.
About the Role
As a Full Stack Engineer on the ChatGPT Ecosystem team, you will help design and build the platform that powers ChatGPT Apps and developer integrations.
You’ll work across the stack—from developer-facing interfaces to backend systems—to ship features that make it easier for developers to build, deploy, and scale applications within ChatGPT. You’ll collaborate closely with product managers, researchers, and cross-functional partners to translate evolving model capabilities into robust, developer-friendly tools.
We’re looking for engineers who enjoy building platforms, care deeply about developer experience, and are excited to shape the foundation of a new application ecosystem.
This role is based in San Francisco or New York City. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.
What You’ll Do
Build end-to-end platform features that power the ChatGPT Apps SDK and broader developer ecosystem.
Design and implement APIs, services, and interfaces that enable developers to build and integrate applications within ChatGPT.
Improve developer workflows, tooling, and documentation to make building on ChatGPT intuitive and scalable.
Partner closely with Product, Security, Trust & Safety, and Research to ship high-quality, safe, and reliable platform capabilities.
Iterate quickly based on developer feedback to continuously improve the platform and ecosystem experience.
Help define the technical direction and architecture of the ChatGPT Ecosystem as it scales.
You Might Thrive Here If You
Enjoy building high-quality product and platform experiences across the full stack.
Are comfortable owning features from concept to production in a fast-moving environment.
Have experience working with modern web technologies and backend systems (language/framework flexibility is fine).
Have experience building developer tools, APIs, or platforms (e.g., SDKs, integrations, open source projects, or internal tooling).
Care deeply about developer experience and designing intuitive, well-crafted interfaces and abstractions.
Like tackling ambiguous problems and shaping them into clear, scalable solutions.
Are excited about building foundational systems that other developers will build on top of.
Have experience with or interest in AI-powered applications and LLM-based systems.
