Senior Software Engineer, Map Ads, Machine Learning

Google Google · Big Tech · Mountain View, CA +1

Senior Software Engineer to build next-generation modeling and quality infrastructure for queryless ad formats, using LLM-based distillation and differential modeling. Will lead technical roadmaps across retrieval, auction, and measurement, and develop evaluation frameworks where LLMs simulate user personas to predict ad quality. Focus on personalization and implicit user intent in local discovery.

What you'd actually do

  1. Move to high-performance ML models utilizing factorization for sub-millisecond relevance optimization.
  2. Build a new pRelevance model that incorporates deep personalization signals through non-traditional techniques like differential modeling and transfer learning.
  3. Leverage Large Language Model (LLM) based distillation to teach models what is relevant in scenarios where manual dataset creation is unfeasible.
  4. Develop evaluation frameworks where LLMs simulate user personas to predict true ad quality.
