Facebook has begun a search for a chief information officer after Timothy Campos announced he would depart after almost six years in the role.
Campos will leave the social network at the end of the year. He said it would be difficult to "walk away from a place my kids consider magical".
"It has been my privilege to be a part of what Facebook has accomplished, knowing we have changed how our world interacts. I am very proud of the organisation I've built and what we've accomplished over the last nearly six years — we've redefined what IT can do for a company," Campos wrote in a Facebook post.
"Although I'm not ready to share details about what I'm planning to do next, I will say that my passion has been and continues to be building next generation enterprise software that helps to re-imagine how work is done."
Facebook has put out the call for a "strategic, innovative and experienced" CIO that has history leading teams of over 500 in size and 15 years experience heading IT in a multinational.
"The ideal leader is an enterprise-oriented technologist with experience developing, deploying and supporting enterprise products at scale," its job ad states.
"A key focus for the new CIO will be to enable to cross-functional productivity of all Facebook employees and is responsible for overseeing the overall global information technology function."
