About the Program
The Circle Internship Program is a 12-week, remote-first experience running from May 26 to August 14, 2026, designed to give interns hands-on experience building the future of global finance. Interns work on meaningful, real-world projects that support Circle's mission to enable the frictionless exchange of value.
The program includes three in-person experiences designed to deepen learning and connection:
- Circle Forward Week in Miami
- Development Week at Circle's New York City HQ in One World Trade Center
- Final Showcase Week in the San Francisco Bay Area
Throughout the summer, interns are supported by managers, mentors, and a close-knit cohort, with opportunities for learning, growth, and exposure to leaders across the company.
