Santosh Janardhan, who built Meta's infrastructure from the ground up over 15 years, is stepping down as the company's head of infrastructure. He will transition to an advisory role on Meta Compute before departing next year.

Dave Brown, who joined Meta as vice president of infrastructure earlier this year, will take over Janardhan's responsibilities. Brown spent 19 years at Amazon leading compute, cloud and artificial intelligence teams.

Janardhan joined Meta in 2009 and oversaw the scaling of infrastructure that powered the company's social networks through years of explosive user growth. Earlier this year, he was given the additional charge of leading Meta Compute, a new initiative tasked with coordinating the company's data center expansion and AI hardware strategy.

Meta's infrastructure spending has surged as the company races to secure GPU capacity and build custom silicon to compete in generative AI. The shift signals confidence that Brown's Amazon pedigree—he worked inside one of the world's largest cloud operators—positions him to manage the capital intensity of Meta's compute strategy.

Janardhan's departure follows a pattern of leadership transitions at Meta as the company recalibrates spending priorities. His move to an advisory role preserves continuity on Meta Compute during the handoff.

Meta shares closed at $628.77, down 2 percent.
