What are the responsibilities and job description for the 2026 PhD Residency, Agentic AI Resident, Moonshot Tools & Infrastructure position at X, The Moonshot Factory?
About Us
X is Alphabet's moonshot factory. We are a diverse group of inventors and entrepreneurs who build and launch technologies that aim to improve the lives of millions, even billions, of people. Our goal: 10x impact on the world's most intractable problems, not just 10% improvement. We approach projects that have the aspiration and riskiness of research with the speed and ambition of a startup.
Project Goal: We are developing a rich ecosystem of interoperable agent-driven tools that enable Xers to seamlessly access, learn from, and synthesize prior knowledge accumulated at X—and ultimately, to automate parts of the moonshot development process itself. As part of this effort, you will work with both our central AI team and multiple project teams to develop and deploy next-generation moonshot development tools.
How You Will Make 10x Impact
