## About the role

You will build and operate the security systems that let Parallel ship quickly without creating avoidable risk. You will work across application security, secure defaults, AI-assisted security tooling, and the unique attack surface of agentic systems that consume untrusted web content. You will fix real vulnerabilities when they appear, then change the underlying systems so the same class of issue is harder to introduce again.

## What they're looking for

- Significant software engineering experience, including several years focused on product or application security
- Strong experience with web and API security, including authentication, authorization, SSRF, IDOR, injection, and multi-tenant isolation
- Built frameworks, libraries, or secure defaults that reduced entire classes of vulnerabilities across a codebase or engineering organization
- Experience building security tooling using current AI models, such as automated code review, threat modeling, triage, agent harnesses, or evaluation systems
- Experience securing systems that process untrusted inputs, especially LLM or agentic systems
- Ability to work independently as the primary security owner and make clear prioritization decisions
