Product Security Engineer

We are looking for a Product Security Engineer to build the systems that triage and validate bug bounty and other externally reported security findings, not to work the queue, and this role suits a software engineer moving into security or a security engineer with a strong engineering background. You will build large language model (LLM) and agent-based tooling that validates findings, traces them to their root cause, and opens fixes for well-understood vulnerability classes. This is a hybrid role based in San Francisco or New York City, with three days a week in the office.

• Build the systems that take in externally reported vulnerabilities and assess validity, severity, and reproducibility at a volume manual triage cannot match
• Build LLM and agent-based analysis that validates business logic, authentication, and design-level findings, not just known signatures
• Build systems that trace validated findings to their root cause and propose, and increasingly open, fixes for well-understood vulnerability classes, with human review gates
• Own the bug bounty program, including scope, policy, and researcher engagement, and feed every resolved report back into automated triage
• Extend the tooling into security testing capabilities that customers can use on what they build and deploy

• 5+ years of software engineering or security engineering experience, building and shipping production systems or internal tools
• Wrote production code in JavaScript/TypeScript on Node.js, with hands-on experience in web frameworks such as Next.js or React
• Built with LLM or agent-based tooling
• Reproduced and assessed externally reported vulnerabilities, including judging severity

• Built security automation used across an engineering org, not just for your own team
• Built systems that auto-generate or propose code fixes, not just findings
• Tested or secured multi-tenant platforms where customer-built applications run on shared infrastructure

• Competitive compensation package, including equity.
• Inclusive Healthcare Package.
• Learn and Grow - we provide mentorship and send you to events that help you build your network and skills.
• Flexible Time Off.
• We will provide you the gear you need to do your role, and a WFH budget for you to outfit your space as needed.
