Data Scientist I, Amazon Currency Convertor

Want to apply data science to one of Amazon's fastest-growing payment businesses, serving millions of sellers and buyers across 20+ global marketplaces? As a Data Scientist I on the cross-border payments science team, you will build and deploy production models that power real-time FX risk monitoring, generative AI seller chatbots, and multi-agent AI tools. You will work end-to-end—from problem framing through production deployment on AWS—delivering solutions that directly influence billion-dollar payment flows. This is a high-visibility, small-team environment where your work informs senior leadership decisions and creates measurable impact for customers worldwide. Key job responsibilities - Build, tune, and evaluate large language models and generative AI applications, including seller-facing chatbots and multi-agent AI tools for the cross-border payments business. - Develop and deploy real-time statistical and machine learning models for FX risk monitoring, validating your data, assumptions, and results throughout the process. - Gather and use large datasets from multiple sources across global marketplaces to design production-ready solutions that meet customer needs and team goals. - Write accurate, clear, and mathematically rigorous technical documents that communicate model performance and business impact to both technical and non-technical audiences. - Partner with engineering, business, and science teams to translate payment-domain problems into data science solutions and ensure smooth deployment on AWS. A day in the life You will spend your morning reviewing model outputs from production FX risk systems and tuning generative AI prototypes for seller chatbots. In the afternoon you might pair with an engineer to deploy a new model version on AWS, then present preliminary results to senior leadership. Throughout, you will seek feedback from senior scientists on your methodology and collaborate with cross-functional partners to refine problem framing.

We are the science team behind Amazon's cross-border payments business, supporting products that serve millions of sellers and buyers across 20+ global marketplaces. Our team is small and at an inflection point—we are expanding our generative AI capabilities, building multi-agent systems, and strengthening real-time risk models. You will join a group that values end-to-end ownership, from research to production, and whose work directly shapes decisions on large-scale payment flows.
