This is a small, selective internship for exceptional high school students and recent graduates whose technical work already stands out well beyond what we typically see at this stage. We are not looking for potential or credentials alone. We are looking for students who can show, through what they have built, researched, or contributed, that they are ready to do substantive engineering work with a Stripe team. You will spend 12 consecutive weeks between May and August working in person from Stripe’s San Francisco or Seattle office on a scoped engineering project. You will own a problem end to end with support from your manager and teammates, contribute to Stripe’s codebase, and learn how engineers build reliable systems used by millions of businesses. Recent Stripe intern projects include expanding Payments Foundation Model capabilities to improve generalized anomaly detection, building more approachable fraud controls, creating safer payouts, and developing user-facing solutions that prevent costly pricing mistakes and make merchant checkout setup easier. You will work alongside Stripe’s collegiate interns and full-time employees, participating in the same team environment and building relationships across the broader Stripe community. This role is not a trainee or classroom-based program; you will be expected to contribute to your team’s work and produce high-quality output under technical review.
