Facebook executive Marne Levine, who is vice president of global partnerships, has emerged as the leading internal candidate to fill the company’s newly formed chief business officer role, according to a person familiar with the matter. If appointed, Levine will have the job of maintaining Facebook’s rapid advertising growth while navigating fallout from Apple’s privacy changes and future policy blowups that may alienate advertisers.

The company has been conducting a search to fill the high-ranking position since Chief Revenue Officer David Fischer announced plans to step down this year. The new position will oversee both Fischer’s organization and Levine’s team, which is responsible for non-advertising partnerships with companies such as telcos that broaden Facebook’s reach. Levine would bring experience in managing relationships with some of Facebook’s largest customers and in handling Facebook’s thorny policy problems.
