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!

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.

This is a software engineering role first. Security curiosity matters; a dedicated security background doesn't.

What you'll work on

The security team operates as a true generalist function. Right now that means:

• Designing and building IAM systems that enterprise customers use to manage PII across global teams

• Supply chain security as Persona's AI tooling and integrations expand

• Building secure, convenient internal tooling for engineers as we scale AI usage

Must-haves

• 5+ years of software engineering experience

• You've built and shipped systems at scale, not just advised on them

• You own implementation end-to-end, from design to delivery

• Clear communicator who can work across teams without losing technical depth

Nice to have

• Proficient in Ruby on Rails

• Experience with IAM, authn/authz frameworks, or identity protocols (OAuth, SAML, OIDC)

• Familiarity with software supply chain security, secure SDLC, or AI/ML security risks

• You've worked somewhere where PII or sensitive data was the core product

The team

Small, senior, and intentionally so. High ownership from day one. This isn't a team where your work disappears into a large org.

Full-time Employee Benefits and Perks

For full-time employees (excluding internship and contractor opportunities), Persona offers a wide range of benefits, including medical, dental, and vision, 3% 401(k) contribution, unlimited PTO, quarterly mental health days, family planning benefits, professional development stipend, wellness benefits, among others. While we believe competitive compensation and benefits are a critical aspect of you deciding to join us, we do hope you consider why our core values and culture are right for you.
