AI hiring in California

California is the largest AI job market in the United States by a wide margin, and the only one where every layer of the stack hires at scale. The Bay Area concentrates frontier labs alongside the cloud, chip and consumer platforms built around them, while Los Angeles and San Diego add defence autonomy, biotech and games. Anduril Industries, Waymo, Roblox, Gilead, Pinterest, Crusoe and Moloco all hire in the state, and the mix stays notably even across applied AI, machine learning engineering, data platforms and infrastructure.

  • • California has no comprehensive AI act; the CCPA and CPRA are the binding baseline for personal data used in AI systems.
