The Seattle-based retailer is already looking for managers, but Lindsey said the company didn’t yet have estimates for when the new facilities would be operating and fully staffed.

About 90 percent of the jobs are expected to pay more than $30,000 annually, said Walter Williams, Edwardsville’s economic development director. Amazon says they will offer a benefits package, including retirement, stock awards and “generous” maternity and parental leave benefits.

Williams said officials anticipated one of the facilities to be open by October but didn’t have a date for the second one.

The new Amazon warehouses are expected to draw workers from throughout the region. And for Madison County, the new jobs couldn’t come at a better time. They could help soften the blow from the layoffs of 2,000 workers at United States Steel’s Granite City mill, which idled earlier this year and will remain closed for an unknown amount of time because of low steel demand.

“When you can add 1,000 permanent jobs to the region, that of course is a big plus,” Madison County Chairman Alan Dunstan said, adding later: “I can’t tell you how pleased we are about having a company like Amazon locating here.”
