Senior Software Engineer - Rails

About Us

We’re Bolt.new by StackBlitz!

We’re the team that brought you WebContainers, the first-of-its-kind technology that made it possible to run Node.js right inside your browser. That breakthrough kicked off our journey in 2019, and it’s what powers the online IDE used by over 1 million developers every month.

We built Bolt.new — an AI-powered app builder that helps you create, edit, and deploy full-stack web and mobile apps instantly in your browser without installs or setup.

We’re a fully remote, globally distributed, and deeply collaborative team passionate about building the future of software development.
