Applied Scientist II, WW Integrated Marketing Systems & Intelligence

Applied Scientist Opportunity

WW Integrated Marketing Systems and Intelligence (WIMSI) is seeking a highly motivated Applied Scientist to develop machine learning solutions that transform how Amazon reaches and engages customers at global scale. In this role, you will partner with scientists, engineers, and product managers across the US and EU to design and deploy models that power personalized, automated marketing across the funnel—from awareness to conversion. You will take ownership of the end-to-end scientific process: from problem framing and data exploration, to model development, evaluation, and deployment in production systems.

You will work on high-impact, customer-facing initiatives that require innovative use of ML and statistical methods, including response prediction, content selection, attribution modeling, and experimentation design. Your ability to combine deep analytical thinking with a strong understanding of scalable systems will be key to delivering measurable business value.

To be successful, you must be comfortable working independently in a fast-paced environment, balancing short-term delivery with long-term innovation. You should demonstrate scientific rigor, strong coding and modeling skills, and the ability to communicate complex ideas clearly to both technical and business stakeholders.
