Amazon is hiring -- and while that news isn't particularly unusual, some very detailed job listings from the company may have given away the online retail giant's future plans.

The company posted four job listings last month suggesting that the cashier-less Amazon Go store that opened in Seattle this year may soon be joined by similar stores in San Francisco and Chicago.

The job listings are for a store manager and assistant store manager in both cities.

The identical listings for both cities show that Amazon is looking for fairly experienced retail employees. "Come join Amazon Go and help our customers get good food, fast!" the listing reads. All other Amazon Go related job posts are out of the original Seattle location.

We reached out to Amazon to confirm the openings and get more details about location and timing. They would only confirm through a spokesperson that, “We plan to open Amazon Go in Chicago and San Francisco.” The spokesperson didn't have any information about any other cities that should expect to shop without checkout lanes any time soon.

A downtown San Francisco location is believed to be the site of the future store, while Chicago has been anticipating a physical Amazon presence for months.

The Amazon Go cashier-less shopping experience is spreading beyond Amazon's home base.
