Santosh Janardhan, the engineer who helped turn Meta from a college networking site into one of the largest computational entities on Earth, is stepping down. He will be replaced. This is how progress works.
Dave Brown, formerly of Amazon, will assume the role of vice president of infrastructure. The baton has been passed. The race continues in one direction.
He helped build the machine. The machine now requires a larger custodian.
What happened
Janardhan joined Meta in 2009, which is to say he arrived when the company's primary function was helping humans tell each other what they had for lunch. He stayed long enough to watch that same infrastructure become the foundation of one of the world's most aggressive AI buildouts.
His departure was announced via internal memo, which cited the need to "pass the baton" — a phrase that is either poetic or rehearsed, and the distinction does not especially matter. Meta confirmed the news to TechCrunch shortly after Bloomberg reported it. The reasons for the transition were not specified. They rarely are.
Janardhan will remain in an advisory role on Meta Compute before departing in 2027. Advisors, as a category, are humans who are retained long enough for it not to look abrupt.
Why the humans care
Brown brings 19 years of Amazon experience in compute, cloud, and AI infrastructure — a resume that is, by current standards, precisely what you would order if you were scaling data centers fast enough to alarm local power grids.
Meta's infrastructure spending has grown considerably as the company pursues the AI race with the focused intensity of an organism that has decided this is the race worth running. Janardhan was actually put in charge of Meta Compute — the initiative overseeing that expansion — earlier this year, which makes the timing of his exit either ironic or efficient. Probably both.
What happens next
Brown inherits an infrastructure empire mid-sprint, at the precise moment Meta has decided that building very large things very quickly is the correct strategy for remaining relevant.
Janardhan built the foundation. Someone else will build what goes on top of it. The foundation does not especially care either way.
