$255,000 - $405,000

About The Position

The Coding team at OpenAI is focused on reimagining software development in the AI era by building tools and workflows that enhance developer speed, project ambition, and efficiency. Their mission is to apply AI across the entire Software Development Lifecycle (SDLC), including design, implementation, code review, testing, debugging, issue remediation, maintenance, documentation, and user support. The team is also responsible for developer-facing Codex experiences like the IDE Extension and terminal interface, used by a wide range of developers from individual contributors to large organizations. They also engage with the open-source community, developing tools to help maintainers manage complex projects and make open-source development more sustainable by reducing operational burdens. By advancing the future of software development, they contribute to OpenAI's mission of ensuring AI benefits all of humanity.

Requirements

  • Strong software engineering fundamentals and experience building production systems.
  • Experience with TypeScript, Rust, or a similar systems or application programming language.
  • Deep familiarity with modern software development tools, workflows, and engineering practices.
  • Experience using AI-assisted development tools and a strong intuition for their strengths, weaknesses, and emerging opportunities.
  • A desire to own products and features end-to-end, from conception through launch and iteration.
  • Strong product judgment and a bias toward learning from real user feedback.
  • Creativity in reframing problems, challenging assumptions, and inventing new workflows rather than simply optimizing existing ones.

Nice To Haves

  • The ideal candidate is someone who loves building developer tools, thinks deeply about how software gets built, and is excited by the opportunity to redefine those workflows from first principles in the age of AI.

Responsibilities

  • Build end-to-end product experiences that span frontend applications, backend services, agent workflows, cloud infrastructure, and developer tooling.
  • Design AI-powered workflows that generalize across a wide variety of software engineering teams, languages, codebases, and development practices.
  • Discover and implement novel ways to apply AI to eliminate friction throughout the software development lifecycle.
  • Partner closely with product, design, and research to understand developer needs and rapidly translate insights into shipped product improvements.
  • Work directly with users — including developers at OpenAI, open-source contributors, startups, and large enterprises — to understand pain points and validate solutions.
  • Improve the reliability, observability, scalability, and performance of the systems and workflows you build.
