In the posting’s own words
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. 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.
What it asks for · 1
- Wrote production code in JavaScript/TypeScript on Node.js, with hands-on experience in web frameworks such as Next.js or React
Also a plus
- 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
What the job covers
- 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
