The state Commerce Department said Thursday that iQor US Inc. plans to hire 320 workers by the end of the year as part of a $391,500 expansion.

The investment is expected to increase employment at the 42,000-square-foot call center at 8440 Dorchester Road to more than 700 workers. The state Coordinating Council for Economic Development approved a $50,000 set aside grant for property improvements related to the project, the Commerce Department said.

New York-based iQor has operated the Dorchester County call center since about 2007. It handles customer-service calls for an array of corporate customers.

"North Charleston has consistently been a highly successful operation for many years, and so it was an easy decision to expand our presence and create jobs in this market," Mason Argiropoulos, chief human resource officer at iQor, said in a statement Thursday.

A company spokesman did not respond Thursday to requests for comment.

In May, iQor said it launched a recruitment drive titled "250 by the 25th" with the goal of hiring 250 employees by May 25 "to meet client growth in several industries, including telecommunications, utilities, financial services and health care." The company's website said those jobs offered an hourly base pay of $9 to $11, with the potential to earn monthly bonuses.

The company, which has been controlled by the private equity firm HGGC since 2010, has 32,000 associates in 17 countries. It made a large acquisition in late 2013 when it agreed pay $725 million to buy the after-market customer support arm of Florida-based electronic parts manufacturer Jabil Circuit.
