Product Engineer, AI (San Francisco)

Bun Product Engineer

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.

We're building Bun's first revenue-generating product.

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.

What You'll Do :

• Rapidly prototype and ship AI-powered features and products
• Talk directly to developers to understand their pain points
• Build full-stack applications from concept to production
• Design and implement experiments to validate product hypotheses
• Own the entire product development cycle from ideation to metrics
• Work closely with leadership to shape product strategy
