What is a Data Engineer at Mastercard?
At Mastercard, a Data Engineer is not just a backend developer; you are an architect of the global digital economy. While the company is famous for payment processing, the Data Engineering teams—specifically within groups like the Global Business Solutions Center (GBSC) and Mastercard Services (Test & Learn)—focus on transforming raw transaction data into actionable intelligence. You are building the engines that power fraud detection, loyalty programs, and business experimentation for clients in over 200 countries.
In this role, you will design, build, and maintain high-performance data pipelines that feed into massive Data Warehouses and analytical platforms. Whether you are working in O'Fallon, MO on internal automation or in Arlington, VA on client-facing "Test & Learn" products, your work directly impacts how businesses and governments realize their potential. You will bridge the gap between legacy systems (Oracle, MS SQL Server) and modern cloud architectures (AWS, Azure, Databricks), ensuring data is secure, accurate, and accessible.
This position requires a balance of technical rigor and business acumen. You are expected to innovate—identifying ways to leverage data to answer complex business questions—while adhering to the strict security and "Decency Quotient" (DQ) standards that define Mastercard’s culture. You are joining a team where data is the product, and your engineering decisions have global visibility.
