About Us We're building a new B2C AI browser that will soon be in the hands of millions. Radically simple, delightfully fast, and enhanced by powerful AI features. Our mission is to simplify and improve daily online activities. We've shipped a beta, and the user base keeps growing daily. The surface area ahead is wide: AI features, system-level interactions, and cross-platform experiences on desktop and mobile. We're looking for a Product Builder to help define the next chapter of the browser - someone who ships their own prototypes, holds strong opinions on craft, and doesn't wait to be told where to start. You'll own a product area end-to-end: frame the opportunity, build the prototype that sells it, ship the experience alongside design and engineering, and measure how it lands. Your work will shape how people move through the web every day. Learn more at ace.ai. What You'll Do Own product areas end-to-end, from discovery through post-launch iteration. Turn ambiguous opportunities into opinionated proposals, backed by research, data, and working prototypes. Prototype the experience yourself - in Cursor, Claude, Figma, or whatever gets an idea into something people can feel. Partner with and ship alongside design and engineering. From kickoff to polish. Monitor performance post-launch and make the call on what comes next. Requirements 4+ years shipping consumer or large-scale complex digital products - as a PM, designer, engineer, or in a hybrid role. A track record of shipping thoughtful, user-centered features end-to-end and iterating on real data. Strong product sense: simplifying complexity, seeing around corners, getting into details. Design taste and UX judgment - specific, defensible opinions about flows, motion, and microcopy. Technical fluency: comfortable reading a spec, pushing on architecture, and working with engineers as peers. AI-native in practice: you build with AI - prototypes, experiments, automations, agents, not just documents. Ana
