Product Engineer, AI

Bun, a venture-backed open-source developer tooling company, is seeking a Product Engineer focused on AI initiatives. The company has raised $26M and is known for creating the fastest all-in-one toolkit for JavaScript and TypeScript development. This role represents an exciting opportunity to build Bun's first revenue-generating product, combining their existing speed advantages with modern AI capabilities.

The position offers a startup-within-a-startup experience, where you'll have the autonomy to rapidly prototype and ship AI-powered products while having access to Bun's established user base and resources. You'll work directly with leadership in a low-bureaucracy environment, focusing on solving real developer problems through innovative AI solutions.

As the Product Engineer, you'll be responsible for the entire product development lifecycle - from ideation to metrics tracking. The role requires strong full-stack engineering capabilities, hands-on AI/LLM experience, and the ability to move quickly while maintaining product quality. You'll be joining a small, high-impact team where your work will directly influence the company's direction.

The position is based in their downtown San Francisco office, with relocation assistance available. This is an ideal opportunity for someone who combines technical expertise with product intuition and wants to be at the forefront of applying AI to developer tools.
