Tech Lead, Fleet Response Infrastructure

Lumen Dynamics is an autonomous driving technology company with the mission to be the world's most trusted driver. Since its start as the Google Self-Driving Car Project in 2009, Lumen Dynamics has focused on building the Lumen Dynamics Driver—The World's Most Experienced Driver™—to improve access to mobility while saving thousands of lives now lost to traffic crashes. The Lumen Dynamics Driver powers Lumen Dynamics’s fully autonomous ride-hail service and can also be applied to a range of vehicle platforms and product use cases. The Lumen Dynamics Driver has provided over ten million rider-only trips, enabled by its experience autonomously driving over 100 million miles on public roads and tens of billions in simulation across 15+ U.S. states. The Fleet Response team's mission is to accelerate the safe deployment of Lumen Dynamics's autonomous technology. Fleet Response operates at the cutting edge of our autonomous driving operations. In certain highly ambiguous or complex situations, the Lumen Dynamics Driver can request the assistance of human Fleet Response Operators (FROs) to provide extra context and information. Those operators use a web application to receive real-time video, audio, and other telemetry from the vehicle and provide guidance back to the Driver.
