Facebook VP of Engineering Jay Parikh Is Leaving the Company

He will be succeeded by David Mortenson

Facebook vice president of engineering Jay Parikh is leaving the company after a little over 10 years.

Parikh revealed the news in a Facebook post Tuesday, saying that he will spend the next few months at the social network to assist with the transition, and he does not have any immediate plans.

Facebook confirmed that Parikh will be succeeded on the infrastructure side by vp of engineering David Mortenson, who has been with the social network since April 2011, while the rest of his responsibilities will be spread among several other leaders of the company’s engineering team.

Parikh joined Facebook in November 2009 after spending two years as senior vp of engineering and operations at social networking website platform Ning Interactive.

Prior to Ning, he worked with Akamai Technologies and NetGravity (which was acquired by Google’s DoubleClick shortly after his departure).

Parikh said in his post, “When I first joined Facebook back in 2009, our entire engineering team sat in one building all on one floor, and we were buying off-the-shelf servers and renting data center space. We supported a few hundred million people mostly using the facebook.com website. I don’t think any of us could have imagined that we would now be supporting a global community of almost 3 billion people using our family of applications mostly on mobile phones.”

Tributes from top brass immediately began appearing in the comments on Parikh’s post.

CEO Mark Zuckerberg: “A lot of what we’ve achieved over the past 11 years just wouldn’t have been possible without you. I don’t think we even had a data center when you joined, and now we share our designs so the rest of the world can catch up! I think the most important thing you built here, though, was our culture—not just around technical excellence in infra and eng, but for the company as a whole. It’s been wonderful watching you grow as a leader, and I’m looking forward to seeing what problems you go solve next. Thanks for everything.”

VP of global marketing solutions Carolyn Everson: “I don’t know if I ever told you this directly, but I, along with all of my colleagues on the business side, hold you up on a pedestal as someone who not only keeps our entire operation running, but also in the way you have led. You are revered here and you will be sorely missed. Thank you doesn’t seem to cut it for what you have done for the company, for the industry and for society.”

Chief technology officer Mike Schroepfer: “Hard to properly summarize everything you’ve done in your 10+ years at Facebook—your impact here has been nothing short of incredible. When you started, we were a few hundred engineers in Palo Alto (Calif.), running mostly open-source software on off-the-shelf servers in leased data centers. Today, we’re tens of thousands of people, on multiple continents, building and running one of the most advanced, efficient and flexible infrastructures in the world. Beyond the amazing technical work, your focus on growing people, the organization and the culture is a big part of why this company is such a special place to be. Although it is bittersweet to have to say goodbye, I’m deeply thankful for the decade we got to work together. Going to really miss working with you every day.”
