Mike Schroepfer, Facebook’s Chief Technology Officer, announced his resignation on Wednesday.

Schroepfer is moving to a part-time position in the company and will be replaced in 2022 by Andrew “Boz” Bosworth, who is currently in charge of the hardware division of Facebook. Schroepfer informed Facebook about his intention to resign on Monday, according to a company registration.

“This is a difficult decision because I love Facebook so much and how excited I am about the future that we are building together,” Schroepfer wrote on his Facebook profile. He added that he would use his extra time on philanthropy and family time.

The leadership change comes after a series of reports in the Wall Street Journal last week that shed light on how Facebook is either ignoring or improperly addressing numerous issues affecting users on its services. These include the impact Instagram is having on the mental health of teenage girls, as well as the way Facebook is being used by drug cartels in Mexico to recruit hired killers.

Bosworth’s appointment as CTO is an indication of the growing priority of hardware in Facebook’s future plans. Earlier this year, the company announced that the Metaverse, a virtual reality space where people can meet, will be a key focus for its Oculus division. This month the company, in partnership with Ray-Ban, announced new data glasses and a new generation of portal video telephony devices.

As CTO, Bosworth will continue to oversee Facebook Reality Labs as well as the company’s augmented reality and virtual reality efforts, Facebook CEO Mark Zuckerberg wrote in a blog post. Zuckerberg also thanked Shroepfer.

Schroepfer has been with Facebook since his arrival as Vice President of Engineering in August 2008 and, according to his LinkedIn profile, has held the position of CTO since March 2013.

His part-time role on Facebook will be that of a Senior Fellow, Schroepfer wrote in his post. In this role, Schroepfer will focus on helping Facebook recruit and develop technical talent and further expand the company’s projects in the field of artificial intelligence, Zuckerberg wrote.
