Amazon is hiring up to 4,400 employees for its Maryland facilities, the e-commerce giant announced Monday, as part of a massive companywide expansion accelerated by booming sales during the coronavirus pandemic.

The planned new hires will add to the Seattle-based online retailer’s 17,500-person workforce in Maryland, it said in a news release Monday.

The company has more than two dozen delivery, fulfillment and sortation centers, as well as Whole Foods Market stores, in Maryland, including large facilities in Baltimore, Sparrows Point, BWI Thurgood Marshall Airport and Cecil County. The state ranks among those with the most employment opportunities within the tech leader, according to the news release.

The company wants to bring on a total of 100,000 new full- and part-time workers across the United States and Canada to handle shipping, packaging and customer orders. That’s in addition to 33,000 new corporate positions Amazon announced last week.

Separately, Macy’s announced Monday that it is seeking Marylanders for jobs at its fulfillment center in Joppa as part of a push to hire 1,000 people companywide. The retailer, which has stores in Bel Air, Columbia, Perry Hall, Security Square and Towson, is holding three hiring events at the Joppa facility in September. Workers will assist with customer orders placed online, and available jobs include warehouse staffers and forklift drivers. Candidates can apply by visiting macysJOBS.com.

With more people confined to their homes during the public health outbreak, online retailers — especially those with the infrastructure already in place — have met unprecedented demand for service.

Amazon has opened 75 facilities already this year and plans to add 100 buildings to its network this month alone, said Dave Clark, senior vice president of worldwide operations at Amazon, in a statement. In July, Amazon reported a 43.4% increase in North American sales in the second quarter and 33.5% worldwide revenue growth.

The company pledged to maintain salaries of at least $15 per hour for all workers and include benefits from day one. Some employees will be eligible for up to $500 in signing bonuses, Amazon said in its news release. Interested candidates can visit amazon.com/apply to learn more and apply.
