Amazon.com plans to add more than 40,000 people to its corporate ranks in the United Statesover the coming months, with over 1,000 of those roles in Massachusetts. It’s part of a hiring spree that includes what the company is calling its biggest-ever recruiting and training event.

The online retailer and cloud-computing company said in a statement that it plans to hold a career fair Sept. 15, continuing a pattern in recent years of inviting job seekers en masse to learn about the company’s open roles.

Amazon didn’t specify where all the positions would be located, but the company’s job posting site on Wednesday listed Seattle; Arlington, Va.; New York; Bellevue, Wash.; and Sunnyvale, Calif., with the most open roles.

Currently, the e-commerce giant has 1,100 corporate openings in Massachusetts, with more than 550 in the Boston area, according to its website. Locally, the company is seeking research scientists for its virtual assistant Alexa, machine-learning engineers, and engineers for its robotics division, among other roles, a company spokesman told the Globe.

“Amazon continues to grow quickly and relentlessly invent across many areas,” Andy Jassy, the company’s chief executive, said in a statement. “We’re hoping that Career Day gives both job seekers and current Amazon employees the support they need to learn new skills or reimagine their careers.”

In Boston, Amazon’s growth plans will likely cement the city’s status as one of Amazon’s largest tech hubs outside of its Seattle headquarters and Northern Virginia. Since opening a small office in Kendall Square in 2013, the company has expanded into offices in Fort Point, the Back Bay, and Medford ― along with its impending expansion in the Seaport. (Many local employees work on Alexa, Amazon Web Services, robotics, and pharmacy technology.)

In January, Amazon announced it would add 3,000 more jobs over the coming years in a new 630,000-square-foot office being built in the Seaport District. That will go up near another building under construction and expected to open early next year that will house 2,000 Amazon engineers, software developers, and other employees, bringing Amazon’s workforce to roughly 7,000 workers in the Boston area. Amazon currently employs 950,000 people in the United States, and 1.3 million worldwide; most are warehouse and logistics workers.

The company’s ranks have swelled during the pandemic, as stay-at-home orders made the case for online shopping. Former CEO Jeff Bezos earlier this year pledged Amazon would focus more on the welfare of its workers, a statement that followed an unprecedented union drive in the company’s warehouse ranks and activism among corporate employees at its Seattle headquarters.

Amazon shares rose less than 1 percent Wednesday on the Nasdaq stock exchange.
