Front-End Developer for a WebOS – Code the Future of Desktop and Web


KerrOS: The Newest Star in Our Innovative Family 🌟

KerrOS is the latest addition to our pioneering group of companies. As the team behind ventures like Loopia, Pingdom, and Dooer, we’re proud to introduce KerrOS as the brightest new member of our family. Join us on this exciting journey as we build the 6th and missing operating system—the WebOS.


Are you ready to push the boundaries of what’s possible in web and desktop integration? At KerrOS, we’re on a mission to build the 6th and missing operating system—the WebOS. We’re creating a seamless experience between the web and desktop environments, and we need your unique skills and passion to make it happen.


About You – The Rare Breed We’re Looking For 🌟

Window Manager Enthusiast: You have a deep appreciation for window managers, compositors, and tiling systems. You understand the intricacies of X11 and Wayland protocols and are excited about making the desktop and web environments work together seamlessly.

React Maestro: You’re not just familiar with React—you know it inside and out. You understand the underlying principles of JavaScript engines and how they interact with HTTP protocols. You keep up with the latest updates from W3C and dive into the detailed papers and RFCs that shape the web.

Standards Advocate: You love standards and patterns around established conventions. You follow protocols closely and appreciate the elegance they bring to complex systems. Building on top of Human Interface Guidelines isn’t just a task for you—it’s a passion.

Accessibility Champion: Accessibility isn’t a burden to you; it’s essential. You understand that everyone has an equal right to access technology, and you believe accessibility should be a standard—not something that’s added later. We are committed to following all standards to ensure inclusivity.

Fast Learner with Unique Abilities: Regardless of seniority, your trademark is that you’re a fast learner. You have always built things in your private time, showing that this has been a passion for a large part of your adult life. We’re excited to meet you.

Spatial Thinker with Rapid Understanding: You have an uncanny ability to grasp complex concepts quickly. Spatial thinking and abstraction come naturally to you. With the help of the latest AI models, you believe you can become an expert in new areas swiftly.

Schema-Driven UI Enthusiast: We’re 100% about schema-driven UIs where interfaces are not designed but mapped together. You, like us, believe this is the only way things can and should be—everything else becomes unmaintainable. We don’t own a Figma subscription! We design with data, schemas, mappings, and components.

UX Visionary: User experience comes effortlessly to you. You’re amazed (and sometimes puzzled) at how larger teams can miss the mark, and you’re eager to set new standards in UX excellence. You see the big picture and the subtle details that make an interface intuitive and delightful. And you have the confidence to know this—so it’s okay to be a bit proud about it.

Passionate Contributor: You may have built or contributed to projects in the open-source community. Your GitHub is a testament to your dedication, filled with projects that showcase your drive to innovate and improve.

Team Player with Drive: While you love diving deep into your own projects, you thrive in collaborative environments. Sharing knowledge and working with like-minded individuals fuels your passion even more.

Have Fun, Work Smart and Hard: This is our life—we are a startup. We don’t feel like we’re working because this is what we do. We believe that you, like us, are at a point in life where you have the time and passion to give to this mission. We find it so fun and rewarding that we can’t leave it, and we know this isn’t for everyone. But we want to build something that everyone looks up to and that moves and iterates fast. If you feel this excites you—then we really look forward to meeting you.
