Key Job Responsibilities Lead the research and development of ML models that personalize advertising decisions for 100M+ customers across 100k+ titles, with production deployment in mind.

Shape the team’s scientific roadmap, identifying high‑impact research directions. Address science challenges across the full ML lifecycle, from exploratory research and offline modeling to online experimentation and production deployment. Understand heterogeneous customer responses and predict variation to inform real‑time advertising decisions. Infer customer preferences and tolerance from indirect behavioral signals in the absence of clicks and conversions. Build systems that adapt ad load, placement, and content to individual viewers at scale. Measure, attribute, and optimize small signal effects requiring rigorous experimental design and causal methodologies. Navigate competing objectives—revenue, engagement, retention, and advertiser value—using principled frameworks for sustainable outcomes. Basic Qualifications 3+ years of building machine learning models for business application experience. PhD or Master’s degree and 6+ years of applied research experience. Experience programming in Java, C++, Python or related language. Experience with neural deep learning methods and machine learning.
