We walk the talk on open-source philosophy: All roles (yes, even design and corporate!) require using Linux distributions as our primary OS whenever possible.You'll also have some points of contact with the frontend, mainly when it comes to passing data between Clojure and the engine.You'll be part of a small team working in Rust on Penpot's rendering engine (built with WASM, Rust, and Skia), on the text editor, and on ongoing performance improvements.• Interest in or experience with reactive programming (at Penpot we use RxJS).• Regular use of LLMs (Claude, Cursor, ChatGPT, OpenCode...) as part of your way of working, among other things to make it easier for you to interact with and integrate into Penpot's Clojure core.• Regular use of LLMs (Claude, Cursor, ChatGPT, OpenCode...) as part of your way of working, among other things to make it easier for you to interact with and integrate into Penpot's Clojure core.• Hands-on experience with frontend technologies, with a good command of JavaScript, browser APIs, HTML, and CSS.
