Yet, if you’ve searched on Google, asked Siri a question, or seen Apple’s Genmoji in action, his work has already reached you. Pang is the archetype of the invisible engineer: rarely on stage, but central to the systems that make digital platforms scale.

In 2006, he joined Google, where he became a principal engineer. His contributions included designing search infrastructure on Bigtable, co-developing Lingvo (a speech recognition framework), and co-founding Zanzibar, Google’s global authorization system still in use across dozens of services.
In 2021, Apple recruited Pang to lead its Foundation Models group. The team, around 100 engineers, built the models behind Apple Intelligence—features such as generative emojis, context-aware notifications, and a redesigned Siri.
And then came July 2025. Pang walked away from Apple and into Meta’s Superintelligence LabsDealroom has a profile for this one. Try Dealroom →, a new division chasing artificial general intelligence. The move was backed by a package reportedly worth more than $200 million, but its symbolism mattered more than the number.
For Apple, his departure was a rupture, one of many in a year of AI talent losses. For Meta, it was another cornerstone in its effort to gather the brightest minds under one roof.
