What this job asks for AI summary

A senior frontend role focused on building a collaborative document editing platform for drug development workflows. The core technical challenge is architecting real-time, multiplayer document editing — including conflict resolution and presence features — using React and TypeScript. The position suits an experienced engineer with strong product instincts who has worked in small, early-stage environments and is comfortable driving technical decisions independently.

Why we read it this way (6)

The 5+ years requirement is stated at the role level tied to React and TypeScript together ('5+ years of production experience building modern web applications with React, TypeScript…'), so it is captured as both overall years minimum and on those individual skills.

Real-time collaborative editing (CRDTs, presence indicators, conflict resolution) is described as a core ownership area under 'What You'll Own' with architectural responsibility, making it a hard gate rather than a nice-to-have; CRDTs is the concrete named concept extracted.

Rich text editor experience (Slate, ProseMirror) and real-time collaboration libraries (Yjs, Liveblocks) appear explicitly under 'Nice to Have' and are marked preferred accordingly.

The role is hybrid in San Francisco (Tue/Wed/Thu in-office, Mon/Fri remote) — it is NOT fully remote.

AI-augmented tooling (Cursor, Claude) is called out as a required working style, but these are framed as workflow accelerators rather than gateable technical skills; no specific tool is hard-required, so they are omitted from the skills list to avoid inflating hard gates.

Startup experience (<50 people) is listed as a required attribute but names no specific technology, so it is not captured as a skill.
