Keith Enright is leaving Google after 13 years as the tech giant restructures its privacy and compliance teams. Matthew Bye, director of competition law, is also departing.

Google’s chief privacy officer, Keith Enright, will depart the tech giant after 13 years, with no plans yet to replace him, as the company restructures its teams in charge of privacy and legal compliance.

Staff were informed of Enright’s departure in mid-May, according to two sources with knowledge of the matter. One told Forbes the news came as a shock to employees, as Enright was well-liked and respected, having steered Google’s privacy team through years in which its data handling practices were held under a microscope by lawmakers, regulators and civil courts.

Matthew Bye, Google’s head of competition law, will be leaving as well, after 15 years with the company and during a critical moment for Google when it comes to antitrust. Last month, the company wrapped up closing arguments in a landmark competition trialbrought on by the Department of Justice, over Google’s contracts with device manufacturers that push users to Google search. Bye did not respond to a request for comment.
