Software Engineer - UI

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.
