Meta's Head of Infrastructure Santosh Janardhan Is Stepping Down

Meta is losing the engineer who spent 16 years building the physical backbone of its platforms. Santosh Janardhan, the company's longtime head of infrastructure and co-head of engineering, will step down next year, Meta confirmed to TechCrunch. His replacement is already in place: Dave Brown, who joined Meta as vice president of infrastructure earlier this year after 19 years at Amazon working on compute, cloud and AI, according to his LinkedIn profile.

Bloomberg first reported the departure, citing an internal memo circulated recently at the company. Neither the memo nor Meta explained why Janardhan is leaving. Meta did not immediately respond to a request for clarification. In the memo, Janardhan framed the move as a need to "pass the baton."

What changes at the top?

Janardhan will not exit immediately. A Meta representative said: "Santosh will stay on for transition and he is moving into an advisory role on Meta Compute." That advisory placement matters, because Meta Compute is the initiative he was tasked with leading earlier this year — the company's effort to scale its data center investments and strategy.

The handover covers two of the most consequential jobs inside Meta:

• Head of infrastructure, the organization running the data centers that serve billions of users across Facebook, Instagram and WhatsApp
• Co-head of engineering, a role Janardhan held alongside his infrastructure duties
• Leadership of Meta Compute, the data center scaling initiative he took on earlier this year

Why the timing draws attention

Janardhan joined the company in 2009, when Facebook was a five-year-old social network. He helped grow it into one of the largest internet operations in existence. His exit arrives as Meta's infrastructure spending has exploded, driven by the race to keep pace with competitors in artificial intelligence. Data centers, GPU capacity and compute strategy now sit at the center of Meta's competitive position against Google, Microsoft and Amazon.

For practitioners, the significance is straightforward. The executive who defined Meta's infrastructure playbook for over a decade and a half is leaving during the company's most capital-intensive buildout phase. His successor brings a different resume — nearly two decades at Amazon, with deep cloud and AI compute experience — which suggests continuity in direction rather than a strategic reset.

What remains unconfirmed

The reason for the departure stays officially unexplained. The memo gave no cause, and Meta declined to clarify when asked. Any claim about internal conflict, burnout or restructuring would be speculation without support in the available reporting. The only on-the-record signal is Janardhan's own "pass the baton" language, and the company's confirmation that a transition period will run into next year.

Brown's elevation, meanwhile, is confirmed by Meta itself. His 19-year Amazon tenure, concentrated on compute, cloud and AI, aligns directly with the demands of Meta Compute.

The open question is whether an infrastructure leader bred in Amazon's cloud organization accelerates Meta's AI data center expansion — or redirects it.
