Senior Applied Scientist, Traffic Quality

Amazon Amazon · Big Tech · IN, KA, Bengaluru · Applied Science

Senior Applied Scientist role focused on building machine learning models to detect sophisticated invalid traffic (IVT) in Amazon Ads. The role involves designing and implementing statistical and ML solutions at petabyte scale, owning the full development cycle from design to deployment, and staying current with scientific advancements. The team works on deep learning, generative modeling, user behavior, anomaly detection, and time-series analysis to protect advertiser spend and maintain marketplace integrity.

What you'd actually do

  1. Define long-term science vision for Traffic Quality driven by advertiser and publisher needs, translating direction into actionable team plans.
  2. Solve strategically important business problems independently, delivering robust, scalable scientific solutions with limited guidance.
  3. Proactively identify technology gaps and business opportunities, determining resource allocation priorities.
  4. Design and implement statistical and machine learning solutions to detect robotic and human traffic patterns across billions of daily ad events.
  5. Own full development cycle for production-level code handling billions of ad requests: design, prototype, A/B testing, and deployment.
