Last week, the ride-sharing company laid off around 100 autonomous-vehicle operators in the wake of an accident in March in which an Uber self-driving car collided with a pedestrian in Tempe, Arizona.
Uber has halted the testing of its experimental vehicles on public roads.
While most of the operators are based in Pittsburgh, Pennsylvania, some are based in the Bay Area, Uber said. The company said it is hiring 55 mission specialists and will prioritize the laid-off employees. Uber also plans to resume its self-driving-car operations in Pittsburgh later this year.
Immediately after the fatal accident on March 18, Uber paused all of its self-driving car operations in Pittsburgh, San Francisco, Tempe and Toronto.
