## About the role

Superhuman Docs' tables started as a custom, in-memory database designed to run in a browser tab. Our customers have pushed it beyond its limits, and as a result we’re making big changes to our storage and calc engine.

## What they're looking for

- 2-3+ years as an EM or tech lead managing a small team (~5), staying close to the code. This is a player-coach role — roughly half management, half hands-on — not a step away from engineering
- You want to build a real product, not just go deep on infrastructure for its own sake
- Nice-to-have: TypeScript, SQLite, Operational Transforms, WebSockets, OPFS, and React. None of these are gates — strong engineers pick them up fast
