Apple Inc is expanding its presence in Texas with a $304 million investment to build a new campus in Austin, which will add 3,600 jobs over the next decade, more than doubling its workforce in the city.

The Cupertino, California, consumer device giant already employs thousands in Austin, whose tasks include handling customer complaints and support.

"Our operations in Austin has grown dramatically over the past decade from less than 1,000 in 2004 to more than 3,500 today," Apple spokesman Steve Dowling said.

Apple plans to add jobs in customer support, sales and accounting.

The company is receiving an investment of $21 million over 10 years from a state fund and also possible incentives from Austin and Travis County, according to Texas Governor Rick Perry, who announced the news on Friday.
