Software Engineer, Intern (Summer 2027)

About Persona Persona is the configurable identity platform built for businesses in a digital-first world. Verifying individuals and organizations is harder — but more important — than ever, with AI enabling fraudsters to launch sophisticated accounts at scale and regulations evolving rapidly. We’ve built Persona to support practically every use case and industry — that’s why we’re able to serve a wide range of leading companies. For example, Reddit relies on Persona for age assurance and verification to comply with online safety regulations, protecting younger users while maintaining a seamless experience. Meanwhile, OpenAI relies on Persona to keep bad actors out, protecting one of the world’s most powerful AI platforms from large-scale abuse in a time when AI is reshaping the way we work and live. We’re growing rapidly and looking for exceptional people to join us! Founded in 2018, Persona is a 250-person Series C startup based in San Francisco, backed by Index Ventures, Coatue, Founders Fund, and First Round Capital. Persona offers flexible building blocks that help businesses fight fraud, stay compliant, and build trust among their customers. For example, Coursera uses Persona to ensure the right person is earning each degree, OpenAI uses Persona to prevent the misuse of ChatGPT, and Lime checks the ages of customers before they ride electric scooters or bikes.
