Facebook’s Chief Technology Officer Mike Schroepfer is stepping down from the social media company, taking on a part-time role while longtime executive Andrew Bosworth will replace him next year.

Schroepfer, known as “Schrep,” has been at Facebook for 13 years and is a close friend of CEO Mark Zuckerberg. He called his decision difficult “because of how much I love Facebook and how excited I am about the future we are building together” but added that his new role will let him focus on personal and philanthropic efforts while staying connected to Facebook.
