e2e is the open source verification layer for the agentic coding era. You describe what should work in plain English, and e2e checks it like a real user would, on web, iOS and Android.
1.5M npm downloads and 12k GitHub stars in the first month.
We're a small team in San Francisco and Warsaw, backed by YC, Credo, Point Nine and Script Capital, and the co-founders of Uber, Snowflake and Vercel. $9M+ raised.
**You'll own the core:** the agent, the web and mobile engines, and the cache that makes runs fast and cheap. You'll ship it, measure it, and fix it when it breaks.
**You're a fit if you:**
* write great TypeScript and have run things in production
* have shipped LLM features with tool calling
* own what you build, end to end
Bonus: browser automation, iOS/Android internals, or open-source projects people rely on.
We look at your GitHub first.
Visa sponsorship is offered for this role.
