Gov. Jay Nixon and Mayor Francis Slay made the announcement Thursday.
The Philadelphia-based company plans what it calls an "application modernization center of excellence" that will work to develop applications for Apple Mac, Apple iPhone and iPad. Officials say the average salary will be $55,000.
The state awarded Unisys $4.5 million in Missouri Quality Jobs program tax credits as an incentive, along with $900,000 in New Jobs Training funding and $212,500 in recruitment assistance.
Nixon's office says Unisys has already begun staffing at a temporary site, with plans to move to the permanent location later this year.
