OpenAISan Francisco, CA

About The Position

We’re looking for backend engineers to help design and scale the systems that will drive the future of AI in finance. We’re a small, specialized team operating like a startup within OpenAI, and we’re looking for like-minded builders to join us. On March 5, we launched ChatGPT for Excel — just the first step in what we’re building in this space.

Requirements

  • 7+ years of professional engineering experience (excluding internships) in relevant roles at tech and product-driven companies
  • Proficiency in one or more backend languages (e.g., Python, Go, Rust, Typescript or similar) and distributed systems concepts.
  • Enjoy building infrastructure that supports billions of requests and petabytes of data.
  • Care deeply about reliability, safety, and performance in production environments.
  • Interest in AI/ML (direct experience not required)
  • Proven ability to thrive in fast-growing, product-driven companies by effectively navigating loosely defined tasks and managing competing priorities or deadlines.

Nice To Haves

  • Former founder, or early engineer at a startup who has built a product from scratch is a plus

Responsibilities

  • Own the end-to-end development lifecycle for new platform capabilities and integrations with other systems
  • 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
