Job description

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 where 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.

As AI tooling expands what engineers can build and how fast they can build it, the attack surface grows with it. Someone proactively needs to own that problem.

What you'll work on

• Drive the full vulnerability lifecycle and how Persona responds to external threats.
• Design and build autonomous systems and AI tooling that scale security across every team and product.
• Partner with product engineers to shape how new features and systems get built securely.
• Shape Persona's presence in the security research community — running the bug bounty program that powers it.

Must-haves

• 4+ years of software engineering experience.
• 2+ years in product security.
• You've translated security risk into product decisions with non-technical stakeholders.
• You've embedded security into an engineering team's SDLC without becoming the team that says no to everything.

Nice to have

• Familiarity with SAST/DAST tooling, dependency scanning, or bug bounty programs.
• Compliance experience (SOC 2, HIPAA) in a cloud-native environment.
• You've built systems where data sensitivity wasn't an afterthought — HIPAA, financial data, identity, etc.

The team

Small and senior by design. High ownership from day one — this isn't a team where your work disappears into a large org. The seniority of the team means you'd have direct access to experienced engineers invested in your growth.

Based in SF

Relocation assistance available.

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.
