Amazon plans to create 400 tech jobs and open a new office in downtown Denver, the company announced Tuesday.

The expansion of Amazon's Denver Tech Hub will more than double the tech workforce in the city's metro area, where Amazon currently employs more than 350 employees, according to the company. Amazon opened an office in Boulder, Colorado, last fall. The expansion will offer job titles spanning software and hardware engineering, cloud computing, and advertising, the company said.

The new 98,000-square-foot office will be located in Denver's lower downtown neighborhood, according to the release.
