Site Reliability Engineer

Bun is an open-source JavaScript tooling company focused on making programming simpler. We've raised $26 million from top investors in Silicon Valley, are among the top GitHub repositories and have a growing community of 33,000 Discord members.

We're hiring an experienced Site Reliability Engineer to scale and maintain the infrastructure that builds and tests Bun's growing suite of unit, integration, fuzz, and benchmark tests. You'll lead our efforts to create a robust, automated test infrastructure that can handle complex test cases across macOS, Linux, and Windows. You'll work directly with our JavaScript runtime team to build and maintain the systems that validate Bun's compatibility with the millions of JavaScript packages that developers use every day.

As our first Site Reliability Engineer, you'll build the foundation for Bun's infrastructure and reliability practices from the ground up. You'll make the technical decisions that shape our reliability standards, from choosing our tooling and automation stack to establishing our testing infrastructure across dozens of operating systems and architectures. As we grow, you'll have an opportunity to lead our future SRE team, who will maintain the infrastructure for Bun’s hosted-JavaScript cloud platform.
