Teleperformance USA announced Saturday that it will hire more than 300 staff members during the next seven weeks.
Teleperformance works with all the major cell phone providers, but Marcie Ballard, the vice president of recruiting, would not disclose which of them the expansion will serve.
"It is for a major wireless company that we have secured a new line of business, one of our existing clients," Ballard said.
The firm began accepting applications for the openings Friday, she said.
"We need to have those folks hired by the end of November," Ballard said, adding that new workers would make $10 an hour.
The company, which has its U.S. headquarters in Utah, serves Fortune 500 companies such as Microsoft, Dell, Apple, AT&T and Priceline.
When Teleperformance came to Augusta in June 2008, it was to handle calls from clients for Florida-based WellCare Health Plans Inc.
Ballard said the facility now serves three clients and has nearly 300 employees. The 50,000-square-foot customer service center is in the old Waccamaw building on Wylds Road near Augusta Mall.
