Job description

TL;DR: You will bring our design systems to React Native and Expo, so the apps coding agents build feel native on iOS and Android.

Why Better Design

We are a small team, early enough that what you build here shapes the product and the company.

What you will own

• Grow our React Native catalog: design systems that install into an Expo app and match the web version.
• Build the preview that shows each design system running on a phone.
• Teach agents the patterns that make a React Native screen feel native, from lists to gestures.

What we look for

• You have shipped React Native or Expo apps to the App Store and Google Play.
• You know where React Native differs from the web, and why.
• You care how an app feels in the hand.

How we work

• San Francisco or remote. Work with us in San Francisco or from where you do your best work. We write decisions down, so nobody needs a meeting to catch up.
• Small team. Each person owns a whole area, from the first sketch to the release.
• Agents do the repetitive work. Coding agents write the boilerplate, run the checks and review each change. People make the calls that need taste.
• We use what we sell. Our own design review checks every screen we ship, this page included.

Our stack

• Next.js, React and Tailwind for the web app
• Hono on Cloudflare Workers for the API
• Postgres on Neon with Drizzle, and D1 for smaller stores
• An MCP server that coding agents install from npm
• Claude Code and Codex for most of the typing
