ABOUT OUSTER

Ouster designs and manufactures sensors and software for engineers, roboticists and researchers building safer and more efficient systems. We have transformed lidar from an analog device containing thousands of components into a digital device powered by a single chip-scale laser array and a single CMOS sensor. The result is a full range of high-resolution lidar sensors that deliver superior imaging at a substantially lower cost.

Our sensor hardware and perception algorithms are deployed in autonomous vehicles, drones, industrial automation and a wide range of other applications. If you are motivated by solving difficult problems at scale, we are hiring across the company and would like to hear from you.
