What we need is a leader who can take it the rest of the way. Requirements What you'll do Own the AI/ML core of the Mosaic platform — retrieval, agents, model routing, evals, and the research that improves all of them. Set the research agenda. Decide what we investigate, what we measure, and what we ship. Lead the research team directly (with hiring authority) and the AI analyst function indirectly. Partner closely with engineering, product, and the CEO to turn research into production capability. Define and own the quality bar for our AI outputs. What you bring MSc or PhD in Machine Learning, NLP, Computer Science, or a closely related field. 5+ years of hands-on industry experience building production AI/ML systems. Real production experience with AI agents — designed, built, evaluated, and improved them. Prior experience managing researchers or ML engineers. Independent research mindset — a point of view on what to bet on next, and the judgment to defend it. Track record of shipping research into product, not only papers or prototypes. Comfortably partnering deeply with engineering and product.
