Another Google employee has joined Anthropic's data center division.

Mike Brinker spent the last four years at Google, including as a data center services manager, construction manager, and program manager.

"This past Friday was my last day at Google," Brinker said on LinkedIn. "The time I spent in [Google Data Centers] was transformational, and I couldn’t be more proud of what the team accomplished in my time there. I will miss the people, but I made connections and friendships that will stand the test of time — and in an industry this small, we’re bound to cross paths soon!"

Brinker joins a number of former Google employees at the company, most notably Anthropic’s head of data center infrastructure, Winnie Leung, and former Google data center construction lead Brett Rogers.

Other hires from Google include Liwen Mao, a staff data center system architect who is now Anthropic's data center design lead. Similarly, after a decade at Google, Adam Johnson in October became Anthropic's data center electrical lead.

Peter Sarossy, a 20-year Google veteran, in January became a data center security engineering staff member at Anthropic. After 17 years, Zach Miller left Google to become the company's data center operations manager. Scarlett Chen, data center engineer for advanced technology and innovation, is now an Anthropic member of technical staff.

Last month, Sana Ouji left Google for Anthropic's new energy team to "responsibly and rapidly scale an ambitious data center portfolio."

This hiring from Google comes despite Anthropic heavily using the cloud company's services.

In October, Google and Anthropic signed a 1GW+ cloud deal with access up to 1 million tensor processing units (TPUs), Google's AI accelerator chip. This April, Anthropic signed with Broadcom and Google for the supply of 3.5GW-worth of TPUs.

At the same time, Anthropic has pledged to invest $50bn on data centers in the US with Fluidstack. Those same projects are being financially supported by Google.

The company also uses AWS, Microsoft Azure, and Akamai cloud services. It also plans to use all of SpaceX-xAI's Colossus 1 data center compute.
