Applied Scientist III, Sponsored Products

About the role

The Sponsored Products and Brands (SPB) team at Amazon Ads is re-imagining advertising through generative AI technologies, changing how customers discover products and engage with brands across Amazon.com and beyond. We combine human creativity with artificial intelligence to improve every stage of the advertising lifecycle, from ad creation and optimization to performance analysis and customer insights. We are dedicated to developing responsible AI technologies that balance advertiser needs and improve the shopping experience.

In this role, you will develop rigorous methods to understand how traffic sources, customer journeys, and onsite experiences influence purchasing and revenue. You will use experimentation, causal inference, statistical analysis, and machine learning to distinguish correlation from true business impact and identify the drivers of performance changes.

You will work with product, engineering, and business partners to translate complex findings into clear recommendations, design measurable interventions, and build tools that support faster diagnosis and better investment decisions. If you are energized by solving complex challenges at the intersection of AI and measurement science, we would love to talk to you.

Key job responsibilities

• Develop methods to understand how traffic sources, customer journeys, and onsite experiences drive purchasing and revenue, using experimentation, causal inference, and machine learning to separate correlation from true business impact.
• Drive or heavily influence the design of scientifically complex software solutions or systems, taking ownership of components and providing system-wide design guidance for both new and evolving systems.
• Define a long-term science vision and roadmap, combining science leadership, technical depth, and business understanding.
• Translate complex findings into clear recommendations for product, engineering, and business partners, and build tools that support faster diagnosis and better investment decisions.
• Mentor junior scientists, raise the scientific bar across the team, and identify opportunities where generative AI can accelerate learning and efficiency.

A day in the life

You might start your morning reviewing anomaly detection outputs to understand a recent shift in traffic patterns, then move into a working session with engineers to refine how an attribution model is served in production. After lunch, you could lead a design review for a new quasi-experimental framework with product and finance partners. Later, you might pair with a junior scientist on their causal inference approach, helping them sharpen their methodology before presenting results to leadership.

Basic Qualifications

• 3+ years of building machine learning models for business application experience
• PhD, or Master's degree and 6+ years of applied research experience
• Experience programming in Java, C++, Python or related language
• Experience with neural deep learning methods and machine learning

Preferred Qualifications

• Experience with modeling tools such as R, scikit-learn, Spark MLLib, MxNet, Tensorflow, numpy, scipy etc.
• Experience with large scale distributed systems such as Hadoop, Spark etc.
