We're creating the third layer of interaction — a personalized AI action layer that lives across all your workflows. If that excites you, and you’re a world-class infrastructure expert, please apply. Why Dex Matters • Flow is everything. Every tab switch, every UI reload, every wait for an AI handoff kills momentum. • The future of productivity is collaborative AI. Dex is an active, real-time partner embedded directly in your browser—the place where your work actually lives. • Context makes or breaks a product. You need systems that understand where you are, what you're doing, and what should happen next. What You'll Build • Core agent components, including memory stores, context compression, inter-agent protocols, planning and tool use. • High performance state management and real-time UI observation systems. • Scalable infrastructure for browser-native AI. Requirements • Expert in React/Next.js, TypeScript, and Python. • Deep browser internals experience. • Proven rapid prototype to production track record. • Preferred: Prior experience with AI/ML infra or agentic systems. Sample Projects • Translating browser inputs (voice, keyboard and mouse inputs, tab changes, DOM) into actionable workflow graphs. • Agentic systems that predict and execute users’ next steps in complex workflows. • A searchable, self-updating memory store for personalized user flow paths.
