Tom Fallows, the man credited with creating Google Inc.’s same-day delivery service, has taken a job with Uber, the company that enables consumers to hail cabs, town cars and ride shares online.

Uber gave no immediate comment on the hire. The service has recently begun to step into e-commerce via a test of a service that allows Uber users to order more than 100 grocery items through its mobile app. The groceries are then delivered by an Uber driver. The move pushed Uber into a field that also has attracted Amazon.com Inc. and the U.S. Postal Service, along with Fallows’ former employer.

Fallows started at Google in 2010 as a product manager, according to his LinkedIn profile. He created Google Trusted Stores—a system that shows consumers how Google rates sites in such areas as returns and shipping times, and offers rebates for poor customer service—along with Google Express, the same-day delivery service that until recently was called Google Shopping Express. Google launched the service in the San Francisco Bay area in March 2013 and recently expanded it to consumers in Chicago, Boston and Washington, D.C.

“It’s been awesome to help this team build Google Express from just a concept to a national service with paying members and dozens of merchant partners,” Fallows said in a statement provided by Google. “Even though the next stage of my career takes me outside Google, I’m really excited to watch Google Express continue to thrive and expand.”
