Member of Technical Staff
Capy, SF
The role
AI coding is a crowded market now, and developers expect first-minute magic and a quality bar that holds across every surface. Meeting that bar means you will have to own the entire product experience and craft it with care.
"Full stack" here means the whole width of Capy: the interfaces developers direct agents from, the agent loop and its tools, the backend the loop re-plans from, the infrastructure the machines boot on, and the layer that talks to every frontier model. You'll make product decisions without a PM, design without waiting on a mockup, and solve the hard engineering problem yourself rather than handing it off. This is a role for people who build with taste and feel the gap between what exists and what should, then close it.
What you will do
- Ship across the whole stack. One day is a new tool in the agent loop, the next is the React surface that shows what it did, the migration behind it, and the Kubernetes change that ships it.
- Set the standard for agent UX. Threads, tasks, diffs, reviews, live machine desktops streamed from our Rust remote desktop: twenty-five agents running at once need an interface that stays legible.
