Software Engineer, Intern, Summer at Circle

Circle is a financial technology company at the epicenter of the emerging internet of money, where value can finally travel like other digital data — globally, nearly instantly and less expensively than legacy settlement systems. This ground‑breaking new internet layer opens up previously unimaginable possibilities for payments, commerce and markets that can help raise global economic prosperity and enhance inclusion. Our infrastructure – including USDC, a blockchain‑based dollar – helps businesses, institutions and developers harness these breakthroughs and capitalize on this major turning point in the evolution of money and technology.

Circle is committed to visibility and stability in everything we do. As we grow as an organization, we’re expanding into some of the world’s strongest jurisdictions. Speed and efficiency are motivators for our success and our employees live by our company values:
