Build and maintain the Jan desktop app across macOS, Windows, and Linux using Tauri. Work full stack across the app: React and Node.js on the application layer, Rust on the native side. Own packaging, builds, and distribution: installers, auto-update, release pipelines, and code signing. Give Linux first-class support: packaging and distribution across common distros. Integrate local model runtimes and app features end to end. Work agent-natively as your default, running agents in parallel with your own review and guardrail discipline.
