About the role

We are an applied AI lab building end-to-end software agents. We're the makers of Devin, the first AI software engineer.

Responsibilities

  • Ship Product and Talk to Users: Own features end to end, from the first line of code to the conversation with the developer who uses it. User feedback directly shapes what you build next.
  • Build Performant and Beautiful Experiences: Craft interfaces across our IDE, web, and CLI surfaces that feel fast, focused, and effortless. Quality is not a final pass; it's built into how you work.
  • Set the Standard for Agent UX: Define interaction patterns for how developers work alongside AI agents. This is new territory with no established playbook. You'll create the conventions that others will follow.
  • Build the Agent and Agent Harness: Work directly on Devin and the core agent infrastructure that powers it. This means building the agent loop, tool use, and the harness that lets Devin operate reliably across real-world tasks.
  • Punch Through Technical Walls: The best developer experiences often require solving hard engineering problems. You won't hand those off; you'll solve them.
  • Move Fast Across Surfaces: Ship across our IDE, web, and CLI products. Context-switch quickly and maintain a high quality bar across all of them simultaneously.

Qualifications

  • Full-stack engineering depth: Strong engineering skills with a natural instinct for product quality; you notice when something is off and you fix it.
  • Developer empathy: Genuine understanding of developer workflows, frustrations, and what delightful tooling actually feels like.
  • Python, TypeScript, and React proficiency: Experience with all three in complex, production-grade products.
  • Independent product judgment: The ability to make sound product decisions without needing extensive process or sign-off.
  • UX and Design Obsession: You sweat the details others overlook: micro-interactions, transitions, response times, empty states, because you know that magical product experiences are built from hundreds of small decisions done right.
  • Developer tools experience: Experience building developer tools, IDEs, or technical products where the user is an engineer is a strong plus.
  • Relevant industry experience: Prior experience at a frontier AI lab, applied AI company, or developer tools company; you know what good looks like in this category.
  • Degree from a top-tier university: BS, MS, or equivalent in Computer Science, Mathematics, Engineering, or a related technical discipline from a highly selective program.
