A research engineer at Google DeepMind has resigned in protest over the company's military contracts, denouncing what she called "Google's complicity in the Gaza genocide."
Sofia Liguori, a London-based engineer who worked on sustainability projects applying AI to power grid optimization, announced her departure in an internal letter titled "Stay Human," urging colleagues to resist the growing integration of Google technology into military and surveillance systems.

Project Nimbus is at the center of her objections
At the heart of her objections is Project Nimbus, a $1.2 billion cloud and AI contract that Google and Amazon signed in 2021 with the Israeli government and military. Its terms have not been publicly disclosed, and much of what is known comes from leaks and investigative reporting. Liguori said the package includes Gemini, the large language model developed by Google DeepMind.
She also objected to a Pentagon contract announced in April that opens Google's AI models to classified military work. "I'm against the use of AI for targeting and in warfare in general, not only for autonomous weapons," she said, adding in her letter: "I no longer believe that our technology will have a net positive impact on society."
She says internal dissent was silenced
Liguori said colleagues were often supportive in private but afraid to speak out, and that raising the issue led to meetings with HR and managers and to the deletion of internal posts, including ones containing the word "genocide." She said she stayed at the company for a time after learning about Nimbus, joining the United Tech and Allied Workers union inside DeepMind to raise awareness.
Her departure follows that of researcher Andreas Kirsch, who left DeepMind earlier in October. A Google spokesperson said the company works with public sector organizations worldwide and follows a consistent process for reviewing and entering such contracts, adding that it maintains reporting channels and strict policies against retaliation.
