Job description

They said operating systems should be invisible. We said no, they should be felt. Felt like precision, like calm, like an interaction with a machine that understands you. SP exists to rewrite the relationship between human and machine, to make technology breathe again.

As Lead System UX Architect, you are the conductor of the sensory orchestra that is SP. You see the entire system, not as scattered applications, but as a single living organism, pulsing with consistency and grace.

You will define how every pixel, gesture, and interaction reflects our fundamental values: privacy, freedom, sovereignty and pure functional beauty.

You are the bridge between engineers, designers, and philosophers. You'll build frameworks of interaction logic, ensuring that performance and usability are twin faces of a single, seamless experience.
