As Mortenson says in the memo, adding that the company, “I’m incredibly proud of everything we’ve achieved over the past two years I’ve been supporting Infra,” added, “survived the biggest capacity crunch in the company’s history (at least in the past decade)” —presumably referring to supply chain constraints brought on by the global pandemic and “managed to stay productive as we shifted to work from home.”

According to the company’s website, Mortenson is in charge of “teams responsible for developing and operating the hardware, network, software and data centres that all Meta services run on.”

He’s worked at Meta for 11 years in various engineering leadership capacities before becoming the helm two years ago. He is quitting his position, but not Meta, for the time being. He’ll take a long vacation and, according to the message, “once I get back, I’ll figure out what’s next for me.”

Earlier, Facebook pulled messaging from the main Facebook app in 2014 as part of its effort to make Meta’s Messenger a unique experience, forcing mobile users to download a separate app to continue using the service. Video calls were first launched in 2015, followed by Instagram cross-app messaging and, finally, cross-app group conversations.
