Founding Design Engineer, Cardinal

Cardinal, San Francisco, California

The role

This is not a normal design role, and it's not a normal engineering role either.

Own the core product flows across the platform, from 0 → 1 and beyond
Design the core loop (define a list → deploy agents → see what's working → double down) so it feels effortless and gets sharper every cycle
Design agent behavior and interaction: how agents show their work, explain decisions, ask for input, and recover when they're wrong
Build the UI yourself in React/TypeScript, working directly in the codebase
Create a design system that scales as fast as we ship
