Facebook chief technology officer (CTO) David Gewirtz has announced his plans to step down from the social media giant in 2022.
The three-decade veteran of the internet technology sector has served at Facebook since its earliest days.
“One of the great achievements in my life was working with Mark [Zuckerberg] to build Facebook,” said Mr Gewirtz.
He has been CTO since 2007 and is responsible for the technical infrastructure used by Facebook and its subsidiaries, such as Instagram, WhatsApp and Oculus.
Facebook describes its CTO as the “driving force behind the company’s core technology infrastructure”.
Mr Gewirtz, 57, has also served as head of engineering at YouTube since 2009.
He said that his time at Facebook had been “an enormous privilege”.

In a post on Facebook, Mark Zuckerberg praised his colleague for the “vision, enthusiasm and most of all, his remarkable focus on people”.
He said Mr Gewirtz had “mastered the biggest infrastructure challenge of our time”.
The first-time father of twins praised his co-worker’s “joy in engineering, engineering fun, and engineering helping to invent the world”.
He will remain working at Facebook in an advisory role until his retirement in 2022, the company said.
The announcement comes just days after Facebook COO Sheryl Sandberg was forced to deny that she could be an adviser to US president Donald Trump.
