Why Join Mastercard's Internship Program

Mastercard's internship program offers more than hands-on work. It gives you the chance to build skills, grow your network, and make a real impact on projects that support business priorities.

About the Team

The Platform Architecture team designs platform architectures and creates detailed Visio diagrams for complex applications and infrastructure. The team works closely with development, infrastructure, networking, security, and operations groups to make sure applications run on scalable, resilient, and highly available platforms.

A major focus is the Decision Management Program (DMP), a critical part of Mastercard's payment ecosystem. DMP has a large infrastructure footprint across Mastercard's in-house data centers and relies heavily on bare metal server environments. The team helps design, modernize, and manage these platforms, which handle high-volume, mission-critical payment processing.

The team includes members in the U.S. and Pune, India, with architects at every stage of their careers. This makes it a strong environment for mentorship, knowledge sharing, and professional development.

As an intern, you will gain exposure to:

  • Enterprise-scale platform architecture
  • Infrastructure and data center design
  • Application architecture and dependency mapping
  • Visio diagram creation and architecture documentation
  • Bare metal and modern platform technologies
  • Real-world payment processing systems
  • Collaboration with global engineering and architecture teams

If you want to learn, explore complex technologies, and work on systems that power global payments, this role is a good fit.

What We Are Looking For

  • Currently enrolled in a Bachelor's degree, with an anticipated graduation date between December 2027 and June 2028
  • Foundational knowledge of cloud platforms such as AWS, Microsoft Azure, or Google Cloud Platform
  • Understanding of infrastructure concepts including high availability, capacity planning, scalability, and micro-segmentation
  • Exposure to Docker and Kubernetes through coursework, projects, or internships
  • Familiarity with Infrastructure-as-Code and automation tools such as Git, Bitbucket, Jenkins, Terraform, Ansible, or Chef
  • Basic knowledge of Java application servers and enterprise application environments
  • Experience with Linux through academic projects, labs, or personal learning
  • Ability to create technical diagrams and architecture documentation using Visio or similar tools
  • Strong analytical, problem-solving, and communication skills, with the ability to learn new technologies quickly

This role is not eligible for Mastercard's work authorization sponsorship. Candidates must be eligible to work in the United States now and in the future without employer sponsorship. For example, students or recent graduates on an F1 visa (including those with CPT or OPT authorization) are not eligible.

Benefits for Interns

  • Mentorship and coaching from experienced professionals and leaders
  • Networking with fellow interns, employees, and senior leaders
  • Professional development focused on career growth and skill-building
  • Exposure to innovative technologies and global business challenges
  • Volunteer, community engagement, and team-building activities

Many interns continue their careers with Mastercard through full-time opportunities, early career programs, or future internships.
