Job Description
Mastercard is a global technology company in the payments industry. Our mission is to connect and power an inclusive, digital economy that benefits everyone, everywhere by making transactions safe, simple, smart, and accessible. Using secure data and networks, partnerships and passion, our innovations and solutions help individuals, financial institutions, governments, and businesses realize their greatest potential. We are seeking a hands-on Principal Forward Deployed Engineer to accelerate delivery across Mastercard Services. Modeled on the forward deployed engineering role that leading technology companies embed alongside their most important customers, this position turns that model inward. You will deploy into Services programs as an internal partner who writes production code, unblocks delivery, and puts AI to work in how we build. Reporting to the SVP of Developer Enablement within the Services Enablement & Transformation (SET) organization, you will move to wherever the need is greatest, adding senior engineering capacity during critical spikes, accelerating roadmaps, and helping teams adopt modern, AI-first practices.

- Exceptional technical breadth, becoming productive quickly across unfamiliar languages, frameworks, domains, and codebases.
- Deep fluency in modern development practices, including CI/CD, automation, cloud-native architecture, testing, and developer tooling.
