Campus Graduate II Summer Internship Program - 2027 Data Science, Finance - New York, NY

About the Role

At American Express, Finance Data Science & Analytics applies advanced modeling, machine learning, artificial intelligence, and statistical techniques to help the organization make scientifically grounded decisions around growth, risk, profitability, and enterprise strategy. Finance Decision Scientists work at the intersection of Finance, Business, Risk, and Technology to develop predictive models, analytical frameworks, and data-driven insights that inform senior management decisions and improve how we forecast, optimize, and manage the business.

This internship is designed for candidates who want to build and apply modeling capabilities to real-world business problems. Interns will work with large-scale datasets, develop and test predictive models, translate business questions into technical modeling approaches, and communicate insights in a clear, structured way. The role requires strong quantitative problem-solving, hands-on programming, and the ability to connect model outputs to business strategy and decision-making.

• Apply machine learning, statistical modeling, and advanced analytics to identify drivers of business performance, risk, customer behavior, and enterprise value.
• Build, validate, and interpret models that inform decisions related to growth, profitability, credit performance, fraud, recessionary preparedness, and balance sheet management.
• Translate complex business problems into structured analytical questions, modeling approaches, and measurable outcomes.
• Partner with Finance, Business, Risk, and Technology teams to embed model-driven insights into strategic decision-making.
• Communicate modeling methodology, assumptions, results, and business implications through clear documentation and executive-ready presentations.
