TikTok lured longtime Microsoft Corp. lawyer Matt Penarczyk away from his compliance and ethics chief position for a new post as the short video-sharing social network’s top lawyer in the Americas. 

Penarczyk worked at Microsoft for more than 18 years and was instrumental in helping the Redmond, Washington-based tech giant build and foster a culture of compliance. He first announced last month that he would be “transitioning to a new role outside of Microsoft,” but did not provide details about his next move at the time.
