Meta named Dave Brown to succeed infrastructure chief Santosh Janardhan, who will remain through Q1 2027 for the transition.

Meta infrastructure chief and engineering co-head Santosh Janardhan told employees he would leave in early 2027. The report identifies Dave Brown as his successor as infrastructure chief, with Janardhan remaining through the end of the first quarter to support the handover.

Janardhan joined Facebook in 2009 and helped develop Meta’s software, hardware, networks, and data centers. His responsibilities also included the company’s custom-chip program, and he became a co-head of Meta Compute in January 2026.

Brown joined Meta earlier in 2026 as vice president of infrastructure after nearly 20 years at Amazon. The reported employee memo did not explain Janardhan’s departure, and the supplied material does not establish that Brown will inherit every additional role Janardhan held.
