Senior Applied Scientist , Amazon Ads

Amazon Amazon · Big Tech · Seattle, WA · Applied Science

Senior Applied Scientist at Amazon Ads focused on building and deploying next-generation ML solutions, including generative AI and LLM applications, to transform the advertising experience. The role involves end-to-end project ownership from concept to production, designing experiments, building models that balance customer and advertiser needs, and developing scalable ML pipelines. It emphasizes shipping solutions at scale that impact billions of people.

What you'd actually do

  1. Research and build next-generation ML solutions — including generative AI and LLM applications — that transform how advertising works
  2. Own end-to-end projects: from messy, ambiguous problems to deployed, production-grade models
  3. Design experiments that validate your hypotheses and measure real business impact
  4. Build models that balance what's best for customers and advertisers — because great advertising should feel helpful, not intrusive
  5. Work cross-functionally with engineers, PMs, and fellow scientists to ship fast and iterate faster
