Application Engineer
About Jan
Jan is an open source AI assistant built by Menlo. It began as a private, offline alternative to ChatGPT and has grown into a general purpose agent that runs open models locally on your own hardware, or connects to frontier models like GPT, Claude, and Gemini when you want them. Give Jan a task and it works on its own until the job is done. Built in public around one belief: AI should be open, private, and answer only to you.
The Role
We are looking for an Application Engineer to build and ship the Jan desktop app across platforms. You will own the application end to end, from architecture through packaging and distribution, working full stack across the web and native layers.
This is a build-and-ship role, not a UI design one. You will care about how the app is put together, how it performs, and how cleanly it gets into users' hands on every platform. This is a lean, agent-native setup, so you will orchestrate coding and execution agents to move fast while keeping the judgment to get the hard parts right.
What You'll Do
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.
