Research Scientist Intern, Youth Safety (PhD)

Meta was built to help people connect and share, and over the last decade our tools have played a critical part in changing how people around the world communicate with one another. With over a billion people using the service and more than fifty offices around the globe, a career at Meta offers countless ways to make an impact in a fast growing organization. Meta is seeking Research Interns to join our Youth and Controls team within Facebook.

Youth safety is one of the most consequential problems at Meta right now — the models you build change what millions of teenagers see every day. Our team owns age-appropriate content experiences across Facebook, including content-understanding and age-understanding models that decide what gets shown and to whom, spanning Teen Accounts, parental supervision, U13 experiences (Messenger Kids), and our most protective content tiers. More concretely, you will work on high-ambiguity, high-impact problems at the intersection of ML, integrity, and personalization: proactive detection of harmful content for youth, age-appropriate ranking and retrieval, safety-aware personalization and controls, and age-signal modeling (stated vs. predicted age reconciliation).
