More than 10 million businesses build on Stripe, spanning the economic frontier—from solo founders to established enterprises—united by a practical focus on growth. The most ambitious companies in the world use Stripe as core infrastructure to grow faster, processing trillions of dollars annually, equivalent to around 1.6% of global GDP.

As an intern at Stripe, you’ll work on projects across our stack that directly impact millions of businesses. You will own problems end to end with the support of your manager and teammates. This is an opportunity to collaborate with some of the most creative and technically rigorous engineers in the industry and learn how to ship high-quality work at scale.

Recent intern projects include expanding Stripe’s Payments Foundation Model capabilities to improve anomaly detection, building more approachable fraud controls, creating safer payouts, and developing user-facing solutions that prevent costly pricing mistakes and simplify merchant checkout setup.

Our internship program is competitive and expectations are high. You will operate as a real member of your team, engage in discussions and technical design, write production-quality software, give and receive feedback, collaborate cross-functionally, and learn quickly by asking great questions and leveraging the latest AI tooling.
