Manage a team of agents from your desktop

Proliferate is building the operating system for modern engineering.

We are building the company in person in SoMa, San Francisco. We care a lot about intensity, craft, and working with people who want to do the best work of their careers. We work hard, and we also take health seriously: company-expensed Whoop, meaningful health and wellness budget, and top-tier insurance.

I (Pablo) finished my master's in AI at 19 and joined Onyx (YC W24) as engineer #1, where I spent a year building enterprise AI search before starting Proliferate. You can see what I shipped there here. We’ll be working closely together.

You’d be one of our first engineering hires and build the core product. This is a high-ownership role across product, systems, and user experience.

We have an extremely small, flat, talent-dense team. We value urgency, taste, truth-seeking, and people who care deeply about the quality and impact of their work.

TypeScript, React, Next.js, Python, Postgres, Redis, AWS, Rust

Top-of-market salary plus meaningful equity, full health/dental/vision, all meals covered, equipment budget, and a monthly health and wellness stipend.
