tl;dr: founding full stack engineer (leaning front-end), 150k-220k + 0.5-1.5% equity, SF🌞

As we all know, the best arguments come to mind after the conversation, when you’re stuck in a traffic jam or standing in the shower — and that’s where they die, too. But this is humans. Leaping AI’s voice agents remember all of their shower thoughts and improve after each interaction 🛁
They also update Q&A lists, adjust to the client’s mood and do A/B testing on their replies, enabling the automation of call centers for support, sales, and more complex ops calls ☎️

It’s a YC startup that is top-1% on revenue in their batch, having doubled it over the 10 weeks at the accelerator. They have raised $4.8M: among the investors is Paul Graham, who only invests in 3-4 startups a year.
Right now Leaping processes more than 100 000 calls per day, with automation hitting 70-80% without drops in satisfaction score 👑

Even though the agents are self-improving, right now they need a little help from a Founding Full Stack Engineer that’s focused on frontend:

⏹️ TypeScript + Next.js, or experience with a similar stack;
⏺️ Python for backend; knowledge of async patterns is a plus;
⏹️ founding engineer experience — or strong experience in a company with <100 people (!) that shows your initiative, autonomy and taste.

The last part is crucial: you don’t need to be told what to do, you have ideas and get them shipped, you’re opinionated and know how to communicate well — and, most importantly, you love all of this 💓

You’ll be joining a super-early stage project, with a million interesting tasks, a chance to build the engineering culture from ground up, and full ownership of features — from a client's idea all the way to production deployment. And equity, of course! 😇

The pay is $150k-220k + 0.5-1.5% equity. The office is in San Francisco, but you can start remotely and relocate later via O1. If you're already in SF, that's perfect!
