Software Engineer, Security
About The Position
Persona builds identity verification infrastructure. Security isn't a layer we add later. It's core to everything we ship. At most companies, a security failure means downtime. Here, it means a real person's identity is compromised. The stakes at Persona are different. AI is raising the bar on both sides: it's making breaches more common and more damaging, and it's letting us build systems in-house that used to be out of reach, changing how we think about build vs. buy in real time. The engineers who can move fast on both are the ones this role is for. This is a software engineering role first. Security curiosity matters while a dedicated security background doesn't. The team runs more like infrastructure than a typical security org: not in a silo, a lot of what we ship is core product code, and you'll be building alongside other engineering teams, not just configuring what they've already built.
