Senior Applied Scientist, Sponsored Products

Amazon Amazon · Big Tech · Seattle, WA · Machine Learning Science

Senior Applied Scientist role focused on building and deploying ML models and Generative AI applications for Amazon's Sponsored Products advertising. The role involves leading end-to-end ML projects, optimizing and deploying models, establishing scalable processes, applying LLM techniques (prompt engineering, fine-tuning, RAG, evaluation), analyzing data for insights, designing A/B experiments, and researching innovative ML/GenAI approaches. The team works with query, shopper, product, and advertiser understanding, as well as retrieval, targeting, and ranking systems, powered by data pipelines, deep learning, NLP, GenAI, and multi-agent workflows.

What you'd actually do

  1. Serve as the technical leader in Machine Learning and Generative AI, driving efforts within this team and across other teams.
  2. Lead end-to-end ML projects with high ambiguity, scale, and complexity—from problem definition to production.
  3. Build, optimize, and deploy ML models into production, partnering with software engineers to productionize solutions.
  4. Establish scalable, automated processes for data analysis, model development, validation, and serving.
  5. Apply strong knowledge of LLMs (prompt engineering, fine-tuning, RAG, evaluation) to build production-grade GenAI applications.
