Job description
from Persona careersAbout 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!
About the Role
Persona builds identity verification infrastructure — security isn't a layer we add later, it's core to everything we ship. When security fails at most companies, systems go down. At an identity verification company, real people's identities are compromised. The stakes here are different.
As AI tooling lets teams ship faster than ever and breaches make headlines every week, the gap between what gets built and what gets built securely is widening. The engineers who are working on closing that gap are more critical than ever.
