Job Description
About the role
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 AI 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.

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.
Analytics baseline: comfortable thinking in SQL-shaped questions and finding the real signal.
Clear, concise communication — written and verbal.
Nice to have
Experience scaling consumer products from concept to a multi-million user base.
Experience with B2C AI products and interactions across mobile and desktop.
A history of shipping side projects, indie tools, or prototypes that escaped into the wild.
This Role Is Exactly Right for You If
You'd rather ship a prototype than write a brief about one.
Given a rough direction, you come back with a plan and a proposed solution.
Your workflow doesn't end in a PRD drafted by AI.
Fast, iterative cycles feel natural, not frantic.
You enjoy collaborating with multidisciplinary teams.
AI Product Builders can come from odd paths. Designers tired of throwing work over the wall. Engineers whose side projects outgrew their day jobs. Indie makers ready for a bigger surface and a team. If you've shipped things users care about and can defend the taste behind them, apply, regardless of what your title says now.
