The Apple Inc. executive in charge of product design for the iPhone and smartwatch is stepping down, bringing a shake-up to the company’s most critical product lines.
Tang Tan, whose title is vice president of product design, is leaving in February, according to people with knowledge of the matter, who asked not to be identified because the move isn’t public. Tan reports to John Ternus, senior vice president of hardware engineering, and the division is reshuffling duties to handle the transition.
