Senior Software Engineer | Kimchi Studio

Join CAST AI to work on Kimchi Studio, a desktop app for autonomous coding agents. You'll own features end-to-end, working with TypeScript, React, Node, and Go. This is a remote-first role with competitive salary and benefits.

• You'll own features end to end: design, implementation, testing, production rollout.
• Multiple agents on separate branches side by side with native git worktree support.
• Every agent action visible, diffable, and undoable.
• Local first on your machine, remote sessions when you need them.
• You'll work directly with product and other engineering teams on problems that don't have textbook solutions.

• You've personally driven a complex product feature from idea to shipped, and you can tell that story with receipts.
• You're a full-stack engineer: TypeScript where the product lives (Electron/React UI, Node services) and Go where the backend lives. Strong in one, ready to go deep in the other, and honest about which is which.
• You have deep debugging and performance instincts: when the app janks or a query slows down, you find the cause through query profiles and flame graphs.
• You care about UX, speed, and polish.
• Bonus: shipping Electron apps at scale (updates, code signing, multi-platform builds), Kubernetes internals, or building your own AI workflows and harnesses at home.
