AI Research Scientist (Technical Leadership)

Meta's Monetization RankingAI Research team advances state-of-the-art AI technologies to optimize retrieval, ranking, bidding, and whole page optimization for Meta ads—driving significant annual revenue across Facebook and Instagram. We are seeking a distinguished AI Research Scientist at the technical leadership level to lead foundational and applied research for Ads AI systems. In this role, you will define the long-term research vision for Ads Ranking models, spanning areas such as generative retrieval, generative ranking, LLM-RecSys, large-scale model architectures, and ML systems co-design. You will shape research programs that influence Meta's advertising ecosystem and the broader AI research community, translating breakthrough findings into scalable, real-world impact.

Responsibilities

• Define and champion a multi-year research vision for Ads AI systems, identifying transformative opportunities in areas such as generative ranking, whole page optimization, large-scale model architectures, and LLM-based recommendation systems
• Lead the design and execution of novel AI research programs in retrieval and ranking, advancing state-of-the-art techniques for personalized ads delivery at scale
• Architect end-to-end AI systems and modeling frameworks for ads ranking that establish extensible technical foundations and standards adopted across multiple research and engineering organizations
• Drive research on next-generation sequence learning, graph-aware LLMs, AutoML, reinforcement learning, and causal learning for ads optimization
• Lead research on ML systems and hardware-software co-design, including quantization, compression, ML compilers, and resource-efficient AI for next-gen hardware (GPUs, MTIA)
• Define new evaluation metrics and experimental methodologies for long-term, cross-team AI research initiatives, connecting them to revenue and engagement priorities
• Influence technical strategy and roadmap across multiple AI research teams and cross-functional partners, acting as a primary point of expertise for leadership
• Produce high-impact publications at premier AI venues (NeurIPS, ICML, ICLR, KDD, WWW, ACL) and contribute to Meta's research reputation
• Mentor and coach engineers and researchers across the organization, providing customized guidance on research design, modeling approaches, and career development
• Partner with product, engineering, and infrastructure teams to translate research advances into reliable AI systems deployed at Meta's ads scale
