Foundational Research Scientist

About the role

At AppLovin, we're powering the future of product discovery and engagement through cutting-edge machine learning. Recommender systems quietly shape the daily lives of billions of people - deciding what we watch, read, play, and buy. They don't just influence culture; they drive trillions of dollars in market value across ads, commerce, and streaming , fueling economic growth and job creation worldwide , and the space is still growing at double-digit rates annually . The modern recommendation stack was established about a decade ago , but we believe the next era of models will look fundamentally different. We're assembling a research team dedicated to shaping that future. We're creating a world-class academic-industrial hybrid research group to advance recommender systems. Unlike academia, your work won't live only in papers - it will be deployed into real products, used by millions, and validated at scale. This is your chance to push the science forward and see your ideas transform how the world discovers content.

Responsibilities

• Drive foundational research to create new recommendation models and paradigms.
