Chris Cox, one of the first handful of engineers hired to Facebook, a close personal friend of Mark Zuckerberg's and, until very recently, Chief Product Officer of the entire suite of the company's products, is departing the company. It also means that Zuckerberg will seize control of Facebook's key products by making the leaders of its most important properties like Facebook, Instagram, and WhatsApp report directly to him-at least for the near term. "This will be a big project and we will need leaders who are excited to see the new direction through".
Facebook's stock is off 2% in after-hours trading on Thursday.
Cox informed the company of his intention to resign on Monday, according to a regulatory filing on Thursday.
For the past two years, Facebook has been roiled by data scandals, a failure to police its service, and a major shift in strategy to focus on privacy.
Daniels had informed the company several months ago of his intention to leave and will stay on through a leadership transition, a person familiar with the matter said.

According to the AP news agency, the documents say a co-operating witness met with Huffman and husband Macy at their home in LA. On Tuesday, Giannulli was arrested at the home he shares with Loughlin , but was released after paying his $1-million bond.
Daniel was in India past year where he met IT Minister Ravi Shankar Prasad to discuss ways to sanitise WhatsApp amid several lynching episodes that happened owing to the spread of rumours on the platform.
He said the new head of the Facebook-owned application would be Fidji Simo, who was previously in charge of video, games and monetization at Facebook.
Daniels has been at Facebook almost nine years, and previously led the company's Internet.org effort, a project aimed at bringing internet access to developing countries.
Zuckerberg wants to evolve Facebook's messaging apps into private forums where people can communicate without worrying about what they are sharing being seen and shared by others. Apart from Mr Koum and Mr Acton leaving Facebook, the founders of Instagram - Kevin Systrom and Mike Krieger - have departed, along with the company's head of communications and policy and its security chief. He also gives the company's orientation to new hires every Monday morning.
Mr Daniels, meanwhile, started as head of Whatsapp after five years of running Internet.org, an initiative to boost internet connectivity around the world.
