Senior Backend Software Engineer - Python

About Ouster Ouster is a NASDAQ listed company with a range of lidar sensors and software solutions built on top of those sensors.
Our advanced vision algorithms and sensor hardware are used in autonomous cars, drones, robots, smart intersections, and many other applications.
We develop software that provides cities with the information needed to better understand and improve their transportation network.
Our small, tight-knit team consists of engineers with backgrounds in Transportation and Software Engineering, dedicated to this mission.
Mission Your role will primarily involve working on Ouster’s Blue City solution with the mission of making roads safer, reducing commute times, and cutting emissions.
We develop a backend infrastructure that enables live streaming of raw lidar pointclouds efficiently to many clients, continuous streaming of data from our edge computers at the intersection to the cloud to perform analytics, and gives users access to the analytics we calculate. You will also help make roads safer by creating analytics like our near miss detection, which finds close calls between vehicles, cyclists and pedestrians.
These analytics allow cities to perform before and after studies on infrastructure changes, measure changes in the rate of close calls, and view 3D recordings of individual events to better understand issues at their intersections.
