Apple has hired a startup founder and former Facebook executive to run its information systems group after departures in that department, according to people with knowledge of the matter.

Timothy Campos will lead the Information Systems and Technology department, better known as IS&T, which handles the infrastructure behind Apple’s online services, customer support and website. Apple refers to the operation as its "nerve center” because it lets employees, suppliers and customers stay connected. The division reports to Chief Financial Officer Luca Maestri.

Mary Demby, the current information chief, is retiring after this year. Her deputy, vice president of software engineering David Smoley, is also retiring after a three-year stint. The people familiar with Campos’s hiring asked not to be identified because the move hasn’t been announced.
