About the Team

Codex for Finance is a specialized team within OpenAI’s B2B Applications organization. B2B Applications builds and operates the products that bring our cutting-edge research to millions of companies and developers worldwide.

About the Role

We’re looking for full stack product engineers to help design and scale the future of AI in finance.

On March 5, we launched ChatGPT for Excel — just the first step in what we’re building in this space.

In this role, you will:

  • Own the end-to-end development lifecycle for new enterprise products.

  • Collaborate closely with product, design and external customers to understand problems and implement effective solutions

  • Work with the research team to improve our next generation of models
