You will design, build, and optimize the recommendation systems that power Fortnite's Discover experience, serving personalized recommendations to one of the largest player bases in gaming across a massive catalog of creator-built experiences. You'll work across the full recommendation stack: candidate generation, content ranking, impression allocation, and real-time reranking. Unlike recommendation systems that operate over a stable catalog, you're working with a massive, rapidly changing content library where new experiences are published daily, quality signals are sparse, and the system's own outputs shape the data it learns from. ### What we're looking for
5+ years of experience building production recommendation or ranking systems, ideally in a UGC, marketplace, or content discovery context
Experience with deep learning for information retrieval and multi-stage recommendation pipelines (candidate generation, scoring, reranking)
Demonstrated ability to design and analyze A/B experiments, with awareness of biases inherent to recommendation systems
Strong Python engineering skills with experience in PyTorch and large-scale data processing frameworks (Spark preferred)
Comfort working in a cloud-based ML environment
Experience with explore/exploit strategies, content cold-start, or counterfactual evaluation methods applied to recommendation
Experience with content understanding models (NLP, vision, or generative AI) used as ranking features
Familiarity with creator economy dynamics and how recommendation design affects content quality and creator incentives
Experience with our stack: PyTorch (TorchRec, Transformers), Ray, Databricks, AWS
Passion for video games and/or experience with gaming analytics
