About the job

In this role, you will build the next generation of modeling and quality infrastructure for queryless ad formats-a complex space where user intent is implicit rather than stated. You will lead technical roadmaps across retrieval, auction, and measurement, utilizing techniques such as LLM-based distillation and differential modeling.

As a technical leader, you will work separately to identify new opportunities, driving quality and business improvements across the entire stack while collaborating with cross-organizational teams in Organic Maps and Personalization. This is a unique opportunity to use advanced AI to shape the future of local discovery at scale and triple our impact over the next five years.

Responsibilities

• Triage product or system issues and debug/track/resolve by analyzing the sources of issues and the impact on hardware, network, or service operations and quality.
• Move to high-performance ML models utilizing factorization for sub-millisecond relevance optimization.
• Build a new pRelevance model that incorporates deep personalization signals through non-traditional techniques like differential modeling and transfer learning.
• Leverage Large Language Model (LLM) based distillation to teach models what is relevant in scenarios where manual dataset creation is unfeasible.
• Develop evaluation frameworks where LLMs simulate user personas to predict true ad quality.
