Onlook is on a mission to bring more people together in code. We built a visual editor that anyone can use to contribute code to real codebases – or, just create a website super fast.

Since launching, Onlook hit #1 on Hacker News, was the #1 trending repo on GitHub—above DeepSeek, Anthropic—and has earned over 19,000 GitHub stars.

If you're looking for an opportunity to be a part of a next-generation design-led company, Onlook might be the right place for you.

Working at Onlook

We’re based in San Francisco, the startup capital of the world, and work closely together in person. Your day-to-day involves working directly with the founders on implementing state-of-the-art techniques for code generation, collaborating with over 80 contributors across the world, answering user feedback, etc. You’ll be working across various parts of the stack and taking full ownership over large projects or features.

We have a very cool office near South Park – it has ultra tall ceilings, tons of natural light, great restaurants and groceries stores just a block away, a full-kitchen, and even a shower. Employees get bespoke black bomber jackets with the Onlook crest embroidered on them, their own standing desk, monitor, budget for tech, and more.

You must be willing to move to San Francisco if you are not already here.

Onlook’s values are a reflection of our founding team and the cultures of the companies we’ve come from. Speed, technical excellence, brand, and attention to detail are what uniquely set Onlook apart.
