Full-Stack Engineer Intern
We're looking for engineers who can turn research prototypes into production-ready systems. You'll work at the intersection of browser automation, agent infrastructure, and intuitive UX that make complex agent behavior understandable and controllable.

Why Dex Matters

  • Flow is everything. Every tab switch, UI reload, or AI handoff delay kills momentum.
  • The future of productivity is collaborative AI. Dex is a real-time partner embedded in your browser—the place where your work actually lives.
  • Context makes or breaks a product. You need systems that know where you are, what you're doing, and what’s next.

What You'll Build

  • Fullstack browser extension interfaces based on research prototypes.
  • End-to-end features using React/Next.js, Python, and SQL.
  • Beautiful and intuitive frontend systems.

Requirements

  • Strong foundation in React/Next.js and TypeScript.
  • Experience building and shipping complex web apps and/or browser extensions.
  • Familiarity with design systems like Figma or Framer.
  • Preferred: Proof of meaningful open-source contribution.
  • Preferred: Strong UI/UX or design portfolio.

Sample Projects

  • Reusable tool call and output components for LLM-generated responses.
  • Building efficient indexing, search, and memory layer architecture.
  • Developing security and guardrails to approve and deny agent requests.
  • Integrating third-party platforms (e.g. Slack, Notion, Gmail) to enable workflows.
