The Seattle-based e-tailing giant said Tuesday it will hire the workers to fill the landmark tower on Fifth Avenue over the next few years as it grows its Big Apple “tech hub” — a plan that looks like a bold bet on offices, even as the pandemic forces most of its employees to work from home.

Still, Amazon said it won’t start moving into the new 630,000-square-foot Midtown office until 2023.

The new staffers will join Amazon’s 800 other corporate and tech workers in New York City in supporting its advertising, devices, music, video-streaming, fashion and other businesses. The e-commerce colossus is also expanding its corporate offices in Dallas, Denver, Detroit, Phoenix and San Diego with plans to add about 1,500 jobs across those cities, according to a press release.

“As we expand our tech hubs and continue to invest in communities across the country, we’re excited to be creating new jobs and investing in New York with a new office in Manhattan that will allow us to accommodate the organic growth of our business teams in the city,” Ardine Williams, Amazon’s vice president of workforce development, said in a statement.

Amazon planned to bring thousands of staffers to the 11-story building at 424 Fifth Ave. when it acquired it for about $1.1 billion, The Post reported in March. WeWork had sought to turn the longtime home of bankrupt retailer Lord & Taylor’s flagship store into its own corporate headquarters, but scrapped the plans amid a slew of scandals that derailed its public offering.

Amazon and other tech giants have let employees work from home amid lockdowns aimed at controlling the coronavirus pandemic, which has also driven a surge in demand for online shopping that’s led Amazon’s profits to explode.

The company has said employees can work remotely until Jan. 8, but Williams told the Wall Street Journal most of its staffers will eventually return to work in person. Amazon did not answer The Post’s emailed questions about what will happen after January.

Amazon unveiled its latest New York expansion about a year and a half after abandoning plans for a sprawling Queens campus that would have created 25,000 jobs in exchange for about $3 billion in tax breaks and grants. The company walked away after local officials and activists criticized the incentive package.
