We’re bringing together two powerhouses: - Generative AI/LLMs for semantic understanding and reasoning - Meta’s world-class ads & organic ranking expertise for optimized decision-making at scale. As part of a rapidly growing ML team, you’ll shape the next generation of User Understanding models and Meta Recommendation Systems, delivering personalization that feels intuitive, adaptive, and truly human.
