Research, Post-Training Data

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 Post-training data research sits at the core of our roadmap and at the intersection of human insight and machine learning. This is the critical bridge between raw model intelligence and a system that is actually useful, safe, and collaborative for humans. Our work combines human and synthetic data techniques to capture the nuances of human behavior and use them to steer models. We research the mechanisms that create value for people to explain, predict, and optimize for human preferenc
