Founding Engineer

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.
