This is an opportunity to work across the entire recommendation stack: context aggregation, AI-driven recommendation generation, and production delivery systems that serve thousands of account team members and millions of advertisers globally. You will work at the intersection of large-scale data systems, Generative AI, and production agent frameworks to build systems that are fast, reliable, and intelligent enough to power autonomous sales workflows.
