Full Job Description

WHO WE ARE We are an applied AI lab building end-to-end software agents. We're the team behind Devin, the first AI software engineer, and Windsurf, an AI-native IDE. These products represent our vision for AI that doesn't just assist engineers, but works alongside them as a genuine teammate. Our team is small and talent-dense: world-class competitive programmers, former founders, and researchers from the frontier of AI, including Scale AI, Palantir, Cursor, Google DeepMind, and others. ROLE MISSION AI coding is a more mature and competitive market than it was two years ago. User expectations have risen sharply: developers now expect first-minute magic, polished experiences, and a consistently high quality bar across every surface they touch. Meeting that bar across an IDE, a web product, and a CLI requires engineers who can own the full experience, not just the implementation. This role exists for engineers who build with taste. You'll make product decisions, push through technical walls, and ship experiences that developers love, without waiting for a PM or designer to define the problem for you. The best product engineers at frontier AI companies are the ones who feel the gap between what exists and what should exist, and then close it. That's what we're looking for. WHAT YOU'LL ACCOMPLISH - 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 infr
