The program includes orientation, training, manager engagement, feedback milestones, networking, and development experiences that help students explore potential full-time career paths, including EDGE, our entry-level development program, where applicable.
What you will gain

Role Responsibilities
  • Assist in the engineering, implementation, maintenance, and support of enterprise infrastructure platforms across distributed, mainframe, networking, database, private cloud, and public cloud services.

  • Support automation, monitoring, observability, and reliability initiatives that improve platform stability, operational efficiency, scalability, resiliency, and secure delivery.

  • Collaborate with infrastructure engineers, application teams, operations teams, architecture, cybersecurity, and other cross-functional stakeholders to troubleshoot issues, validate solutions, and support technology delivery.

  • Participate in research, testing, performance analysis, capacity review, resiliency validation, documentation, reporting, and production readiness activities related to infrastructure services and platform capabilities.

  • Contribute to infrastructure modernization efforts, including cloud adoption, infrastructure as code, lifecycle management, standard build patterns, operational process improvement, and reduction of manual work.

  • Learn how infrastructure changes are governed, tested, released, and supported in a highly regulated environment where availability, security, resilience, and disciplined execution are essential.

What will help you succeed
Required
  • Currently pursuing a bachelor's degree in Computer Science, Computer Engineering, Information Technology, Cybersecurity, Network Engineering, Management Information Systems (MIS), Cloud Computing, Data Science, Electrical Engineering, or a related technical field.

  • Expected graduation date: Fall 2027 or Summer 202

  • Minimum GPA: 3.2
  • Authorization to work permanently in the United States without current or future sponsorship.

  • Foundational understanding of computer systems, networking, operating systems, cloud concepts, scripting, or application/infrastructure support through coursework, projects, labs, prior work experience, or self-directed learning.

Preferred
  • Coursework, projects, prior work, internship, student organization, volunteer, or leadership experience related to infrastructure engineering, cloud platforms, systems administration, networking, cybersecurity, DevOps, database technologies, mainframe, or technology operations.

  • Interest in financial services technology, operational resilience, cloud modernization, infrastructure automation, risk management, production stability, and supporting systems that are critical to market operations.

  • Exposure to one or more relevant tools, platforms, or concepts such as Linux, Windows Server, Python, PowerShell, Bash, SQL, Git, CI/CD, public cloud services such as AWS or Azure, virtualization, containers, networking fundamentals, monitoring tools, infrastructure as code, or ServiceNow.

  • Strong problem-solving mindset with the ability to analyze technical issues, document findings clearly, communicate risks or blockers, and follow through on assigned work.

  • Interest in learning how enterprise infrastructure is designed, governed, tested, secured, released, monitored, and continuously improved in a large-scale IT organization.

What makes you successful
  • Curiosity, initiative, and willingness to ask questions.

  • Strong communication, organization, and follow-through.

  • Analytical thinking and attention to detail.

  • Ability to use feedback and adapt as you learn.

  • Collaboration, professionalism, and accountability.
