You will start by making business definitions, metrics, and dataset relationships reusable across products, delivering key components independently and helping set the team's engineering habits. Early on, you will prototype answers to questions such as how shared metrics are versioned and where data access is enforced, then ship the first shared component with the product team that will use it.\nAbout the Role:\nDesign, build, test, and release shared services, libraries, and pipelines that enable and support other engineering teams.\nPartner with product managers to understand business problems, challenge assumptions, and simplify solutions whenever possible.\nCreate clear and concise design proposals that outline trade-offs, recommendations, and implementation approaches.\nEvaluate enterprise and vendor technologies through proofs of concept to inform build-versus-buy decisions.\nDevelop reusable, versioned interfaces with comprehensive documentation and automated deployment and testing capabilities.\nBuild secure, scalable, and observable components while supporting incident response, troubleshooting, and root cause analysis.\nParticipate in code and design reviews, mentor engineers, and contribute to the team's technology strategy and roadmap.\nAll About You:\nStrong expertise in software design, testing, secure coding practices, CI/CD, and operating production services.\nAdvanced SQL skills and hands-on development experience with Python or other modern programming languages such as Java, C#/.NET, Go, or TypeScript.\nExperience working with modern cloud and data platforms such as Databricks, Snowflake, AWS, Azure, or Google Cloud.\nProven ability to design APIs, reusable libraries, and platform capabilities that are consumed by other engineering teams.\nStrong understanding of data modeling, including entity relationships, aggregation challenges, data contracts, and version control of shared metrics.\nProduct-minded approach to engineering with strong technical communication and documentation skills.\nAbility to understand end-user needs and build solutions that deliver measurable business value.\nPreferred Qualifications:\nExperience working with semantic layers, metric stores, dbt, data catalogs, or business glossary platforms.\nExperience building tools, frameworks, or supporting context for AI agents and large language model (LLM) applications.\nKnowledge of data governance, access controls, row-level security, and handling sensitive or regulated data.\nExperience using AI-powered engineering tools to improve productivity, with sound judgment regarding accuracy, risk, and appropriate use cases.\n• Demonstrated curiosity, continuous learning mindset, and passion for driving innovation through technology.Mastercard is a merit-based, inclusive, equal opportunity employer that considers applicants without regard to gender, gender identity, sexual orientation, race, ethnicity, disabled or veteran status, or any other characteristic protected by law.
