Description

About Bun

Bun is an open-source developer tooling company. Bun is the fastest all-in-one toolkit for building, installing, running, and testing JavaScript and TypeScript. We were born out of frustration with the fragmented, slow JavaScript ecosystem and are on a mission to make JavaScript development faster and more productive.

We've raised $26 million from top investors in Silicon Valley, are among the most popular GitHub repositories, and have a growing community of 34,000 Discord members.

About The Role

As our Product Engineer, you'll rapidly prototype, ship, and iterate on AI-powered products. This isn't about chasing AI hype, it's about finding real problems developers face that we can uniquely solve by combining Bun's speed with modern AI capabilities.

You'll have direct access to leadership, minimal bureaucracy, and the freedom to experiment. Think of this as building a startup within a startup, with the resources and user base of Bun behind you.

This role is on-site at our office in downtown San Francisco. We do offer a relocation bonus if you move to San Francisco.
