Amazon (AMZN) is expanding its workforce again, this time at Amazon Fresh with 1,500 new positions, in addition to adding four brick-and-mortar locations to the Chicago area.

The new grocery stores will be located in Naperville, Bloomingdale, Oak Lawn, and Schaumburg, Illinois, Chicago Tribune reported. The four stores follow Amazon’s first Amazon Fresh location in Woodland Hills, California, which opened in August.

The Woodland Hills store spans 35,000 square feet and offers same-day delivery for Prime members. Store customers are also able to take advantage of Amazon’s Dash Cart, which allows shoppers to scan purchases and skip the checkout line to pay.

The Amazon Fresh stores in Illinois are hiring for full-time, part-time, and flex-time positions, where employees’ job duties will include customer service, cashiering, stocking, food preparation, and packing orders. The hourly wage is $15 and includes benefits.

To apply for a position at Amazon Fresh, job applicants can fill out an application online.

“Our associates are the heart and soul of our Amazon Fresh stores, and we're excited to welcome 1,500 employees to the team as we provide customers with new, low-priced grocery stores in their communities,” Catherine Misko, regional manager of Amazon Fresh stores, told WLS-TV, an ABC affiliate out of Chicago.

“These are great jobs with industry-leading pay and benefits, and we're proud to provide a safe, innovative work environment where associates can grow their careers,” she added.

The move to the Chicago area is a significant expansion for Amazon’s brick-and-mortar Amazon Fresh stores as it looks to compete with Walmart and Target in the grocery business. Amazon Fresh has also announced that it will be adding stores in Northridge, North Hollywood, Long Beach, and Whittier, California, the Tribune said.

Shares of Amazon were trading at $3, 254.97 as of 1:32 p.m. EDT on Tuesday, up $47.76 or 1.49%.
