About the Position

The Network Quality of Service (QoS) team is a team that monitors, troubleshoots, and finds solutions to instances of poor video quality. You will use home-grown tooling to aggregate, query, and visualize video quality metrics as reported by client video players. Through your knowledge of internet routing, BGP routing policy, and our proprietary video distribution system, you will work with other internal teams and external ISP partners to pinpoint, and route traffic around, problematic areas of the internet with the goal of improving video quality to our customers.
