Job Description

Posted on: April 23, 2026

Most frontend roles are just building screens.

This isn’t one of them.

This is a chance to own a real-time, collaborative, AI-native product surface - the part of the system where users actually work, make decisions, and rely on the output.

Think Notion or Google Docs-style interaction design, applied to a high-stakes domain where correctness and usability matter.

Why this role is interesting:

  • You’ll own state-heavy, collaborative UI systems, not just components
  • You’ll work on real-time multi-user editing and syncing problems
  • You’ll integrate AI directly into the product experience, not as a bolt-on
  • You’ll join a small, high-performing team with real product traction
  • You’ll have direct influence over product direction and UX standards

This is one of the highest-priority engineering hires on the team right now.

What you’ll be doing:

  • Building rich editing and collaboration experiences (shared editing, commenting, annotation)
  • Designing UI systems where multiple users interact in real time
  • Solving state, sync, and performance challenges across frontend and backend
  • Working closely with product and design to ship fast and iterate
  • Integrating AI workflows into user-facing interfaces

What they’re looking for:

  • 3+ years building complex web applications
  • Strong frontend foundation (React, TypeScript, Next.js)
  • Experience with rich UI, editing flows, or collaborative systems
  • Comfortable owning features end-to-end
  • High bar for product quality and interaction design

Strong signals:

  • ProseMirror, Tiptap, or Yjs
  • Real-time collaboration / multi-user systems
  • Editor or document-based product experience
  • AI or LLM workflows in product interfaces

Comp & setup:

  • Remote (US)
  • Small team, high ownership, fast-moving environment

Why it’s a good move:

If you’ve worked on editor-like or collaboration-heavy products before, this is a rare opportunity to go deeper on:

  • real-time systems
  • complex UI architecture
  • AI-native product design

…and do it in a setting where your work actually defines the product.
