Meta's Longtime Infrastructure Chief to Step Down in 2027

Santosh Janardhan will step down as Meta's head of infrastructure, with his departure expected next year. Bloomberg first reported the change, citing an internal memo that had recently circulated. Janardhan also holds the title of co-head of engineering.

Dave Brown will replace him in the infrastructure role. Brown joined Meta as vice president of infrastructure earlier in 2026, according to TechCrunch. Before joining Meta, he spent 19 years at Amazon, where his work centred on compute (the processing power that runs software), cloud, and AI.

Janardhan joined Meta in 2009 and has been its longtime head of infrastructure. Earlier in 2026 he was tasked with leading Meta Compute, the company's initiative to scale its data center investments and strategy. He will stay on through the transition and then move into an advisory role on Meta Compute. The handover is therefore not a clean exit from the company's capacity planning. The former infrastructure chief remains attached to the program that sets its direction on data center spend, while the operational remit passes to a newly arrived executive.

Infrastructure at Meta covers the physical and software stack beneath its consumer services and its AI training and inference workloads. Think of it as the plumbing and power grid of a city: largely invisible, yet everything runs on it. The people who run it set the cadence for capacity, silicon sourcing (securing the chips that AI work requires), and the internal platform tooling that engineering teams depend on.

Brown's background is in hyperscale cloud, the very large cloud platforms that rent out computing capacity to many customers. Compute procurement, multi-region capacity planning, and managed AI infrastructure are core responsibilities there. Those are the same areas Meta Compute was created to address, which makes the overlap period between the two leaders a practical question for the organisation rather than a formality.

The broader context here is a company that has moved its infrastructure function into a named, dedicated initiative and is now changing who executes against it. In my view, the next several quarters will say more about the transition than the announcement does. The indicators to watch are whether Meta Compute's reporting lines change, whether Brown inherits the existing roadmap intact, and how the handover of day-to-day responsibilities is scoped before Janardhan's departure.

For engineers working on Meta's infrastructure, the change is a leadership transition rather than a change in technical direction. The timeline is an incoming leader who joined this year, an outgoing leader who joined in 2009 and remains involved in the advisory capacity, and a stated intent for the infrastructure remit to pass between them. Whether that handover produces continuity or a shift in emphasis will become visible only as the transition proceeds through 2027.
