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.

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.

Dex is a personal CRM that reminds you to keep in touch with the people you would otherwise forget.

Dex helps turn your acquaintances into your allies. Going beyond the superficiality of social networks requires commitment. If you remember to keep in touch thoughtfully, you can turn the interesting person you met at a networking event into a friend that has your back.

I built Dex after failing to keep up with the tools I tried (Airtable, Notion, etc) for relationship management. Installing an actual CRM like Hubspot felt like a wrong fit for my informal relationships -- these people were 'my team,' not customers.

Dex is a lightweight personal CRM that’s easy to stick with. Key to Dex is a Chrome extension that enables you to manage relationships while you’re in Facebook, Messenger, Twitter, and the social apps you already use. Dex can also send you actionable reminders (daily, or based on your calendar events) to log your interactions for next time. By using Dex, you can:

Build stronger relationships, by sending you a nudge to follow-up.
Be more thoughtful, by helping you remember where you left off.
Become a superconnector, by making connections you wouldn’t otherwise remember.
