The director of global machine learning planning at Google has left for Meta.

Jeesoo Lee, who spent nearly a decade at the search and cloud giant, has been named the director of product management at Meta Infrastructure.

Lee was involved in Google's rapid growth of machine learning hardware, across GPUs and TPUs, as well as machine learning power forecasting and long-haul network planning.

"Throughout my decade at Google, I've had the privilege of not only observing but also actively participating in the remarkable expansion and transformation of both Google and its data center infrastructure," Lee said on LinkedIn.

On his move to Facebook parent company Meta, he added: "I am extremely grateful for this opportunity, especially at a time the company has shown serious commitment to super intelligence that would be powered by 'super infrastructure'."

Meta CEO Mark Zuckerberg has renewed the company's focus on AI, spending hundreds of millions to hire individual developers (and unsuccessfully trying to hire one OpenAI executive for more than a billion).

On the data center side, the Meta founder this month said that the company would spend "hundreds of billions of dollars" for its superintelligence effort.

"We're actually building several multi-gigawatt clusters. We're calling the first one Prometheus, and it's coming online in 2026," Zuckerberg said. "We're also building Hyperion, which will be able to scale up to 5GW over several years. We're building multiple more titan clusters as well. Just one of these covers a significant part of the footprint of Manhattan."

To save on construction time, the company is deploying compute in temporary tents and dropping backup power generation.
