Proliferate (YC S25) Is Hiring Founding Engineers

About Proliferate

Proliferate is building the operating system for modern engineering: a workspace where engineers and coding agents work side by side.

Our mission is to automate software engineering in a way that makes engineering more human, not less. We believe the best future is not “agents replacing engineers,” but engineers with dramatically better leverage: agents that can take action, stay in context, work in realistic environments, and collaborate closely with the people responsible for shipping.

Proliferate gives teams a shared environment where agents, engineers, and operators can build together. Agents can respond to real engineering signals from tools like GitHub, Linear, and Sentry, work in sandboxed environments that mirror production, and verify their own changes before anything ships.

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.

About the Role

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

Who We’re Looking For

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.

Stack

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

Comp & Benefits

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