Meta’s Infrastructure Chief Is Leaving

Meta is losing Santosh Janardhan, the longtime executive who helped build the company’s technical backbone, with the company telling TechCrunch that he will step down as head of infrastructure and co-head of engineering.

He will be replaced by Dave Brown, Meta’s vice president of infrastructure, who joined the company after 19 years at Amazon working on compute, cloud and AI, according to his LinkedIn profile. Meta said Janardhan will remain for a transition period and shift into an advisory role on Meta Compute before leaving the company next year.

Bloomberg first reported the change, citing an internal memo. TechCrunch reported that neither the memo nor Meta clarified why Janardhan is leaving. The reported explanation in the memo — that it was time to “pass the baton” — says almost nothing, which is sometimes how large companies prefer their departures: consequential, but tidied up.

The role matters because infrastructure is where Meta’s ambitions stop being slogans and start becoming power bills, chips, data centers and limits. Janardhan joined the company in 2009, well before Meta became a company trying to present itself as an AI contender on the same field as Microsoft, Google and Amazon. In that race, infrastructure leadership is not a back-office detail. It determines how quickly a company can train models, serve products and absorb the extraordinary cost of doing both at scale.

That makes the timing notable. TechCrunch points out that Meta’s spending on infrastructure has surged as it tries to keep pace in AI, and that Janardhan had been put in charge of Meta Compute, the company’s effort to expand its data-center strategy and investment. A handover at that moment can be routine succession, internal recalibration, or a sign of pressure that outsiders are not yet being told much about. The public facts support the first. They do not settle the others.

Brown arrives with the sort of résumé Meta wants the market to notice: long experience inside Amazon’s cloud and compute machinery, and direct relevance to AI-era capacity problems. That does not explain Janardhan’s exit, but it does explain what Meta seems to want from the replacement — someone fluent in the industrial side of the AI boom, where the glamour is synthetic and the bottlenecks are not.
