The memo went out on Wednesday and the phrase that traveled was short: “it’s time to pass the baton.” Santosh Janardhan, Meta Platforms’ head of infrastructure and co-head of engineering, told his team he would leave the company in early 2027. He will be succeeded by a former Amazon executive who joined in July.
Janardhan joined Facebook in 2009, when the company was still explaining to advertisers why a social network was worth funding. He leaves a company worth about $1.7 trillion that is building data centers at a pace no one in the industry has attempted, and that reports to investors who have begun asking what the spending buys.
Bloomberg first reported the departure, citing the internal memo. A Meta spokesman confirmed it and said Janardhan will stay through the first quarter of 2027 to manage the transition, then move into an advisory role on Meta Compute, the company’s infrastructure program.
His replacement is Dave Brown, who joined Meta this year as a vice president of infrastructure after 19 years at Amazon, where he worked on compute, cloud and AI. Brown arrived in July. The handover gives him one of the largest capital budgets in corporate history.
Meta said in its third-quarter report that capital spending this year would land between $135 billion and $145 billion. Free cash flow was negative $2.12 billion in the quarter. S&P Global Ratings cited the spending when it revised the outlook on Meta’s AA- credit rating to negative in late October.
Janardhan’s remit covered the whole stack: software, hardware, networking and the buildings themselves. He also oversaw Meta’s custom silicon program, the in-house chips the company designs to reduce its dependence on Nvidia, and in January he was named a co-leader of Meta Compute alongside the executives running the wider effort.
That effort is now led by Dina Powell McCormick, the company’s president and vice chairman, and Daniel Gross, a technical leader. Meta Compute was created to consolidate work that had been spread across product groups, real-estate teams and research, and to negotiate power, land and chips as a single buyer.
The timing is what makes an executive departure worth reading. Meta is committing to data centers whose useful lives run a decade or more, in a market where the price of the chips inside them changes every generation and the cost of the debt that finances them has risen.
A long-tenured infrastructure chief is the person who knows which of those bets can be walked away from. Janardhan’s departure removes a layer of institutional memory at the moment when contracts get longer and the option to stop gets more expensive.
It also fits a pattern. Zuckerberg has spent two years assembling an operating team from outside the company, and infrastructure is now the largest line item that team controls. Brown’s career at Amazon spanned the years in which AWS turned rented computing into a utility, which is the closest analogue to what Meta is building for itself.
The difference is that Meta does not rent its capacity to anyone. Its return arrives as better advertising targeting, more engagement across its apps, and whatever it eventually sells from its models. That is a harder case to make on a quarterly call than a contract with a customer’s signature on it.
Analysts have begun to press on the gap between spending and evidence. The company’s shares have moved on capital-expenditure guidance as much as on revenue, and the negative free cash flow figure gave the skeptics a number to cite. A credit rating outlook is a slower signal than a share price and a harder one to argue with.
The custom silicon effort carries its own risk. Meta designs accelerators to lower the cost of inference on its own products, a project that depends on a small group of engineers who report through the infrastructure organization. A change at the top of that organization is the kind of event that slows a chip program by a quarter without anyone announcing a delay.
Brown inherits a program already shaped. The decisions about where to build, how much to buy and which chips to design were made under his predecessor. What he controls is execution: whether buildings come up on schedule, whether power is available at the substation, and whether racks arrive full.
For investors, the number that matters arrives in January, when Meta guides on capital spending for 2027. A figure near this year’s $145 billion would suggest a plateau and a company catching its breath. A figure above it would suggest the buildout continues under new management at the same pace.
Janardhan’s note said he would help through March. By then the budget will be public, the data centers will be half-built, and the question of whether the money was well spent will belong to somebody else.
