You will develop new ways to understand, represent, and utilize user signals and apply them to ranking and recommendation models. You will work across the ML stack from user signal and feature development to modeling, experimentation, and production to improve the relevance and performance of our advertising systems at scale.
- Develop and improve user signals, features, and representations used by large-scale machine learning models for advertising and recommendation.
- Explore machine learning approaches to learn effectively from large-scale, sparse, noisy, and heterogeneous user signals.
- Improve the quality, coverage, and utilization of user signals, and measure their impact on downstream machine learning models and advertising performance.
- Develop user representations and modeling approaches that effectively incorporate user signals into ranking, retrieval, prediction, and optimization systems.
- Advance large-scale recommendation systems across candidate retrieval, ranking, prediction, and optimization.
- Explore new model architectures and learning approaches to improve recommendation quality and advertising performance.
- Develop scalable approaches for representation learning, feature interaction, and multi-task learning across large-scale user signals.
