About the role
We're hiring a Staff Security Engineer to own and elevate our application security program. This is a hands-on, high-leverage role for someone who wants to be the technical authority on how we build secure software, not just someone who reviews tickets after the fact. You'll work directly with the engineering team to find and fix vulnerabilities, build tooling that scales security across the org, and shape how fomo thinks about security at the architecture and code level.
What they're looking for
- 7+ years in security engineering, with a substantial and recent focus on application security (not primarily corporate/IT security)
- Deep hands-on experience with secure code review, threat modeling, and common vulnerability classes (OWASP Top 10, auth/session flaws, SSRF, injection, business logic flaws, etc.)
- Strong software engineering background, comfortable reading and writing production code, not just running scanners
- Experience building and scaling AppSec tooling and processes (SAST/DAST, SCA, CI/CD security integration) at a growing company
- Track record of driving security into engineering culture through influence, not just gatekeeping
- Familiarity with cloud-native environments (AWS/GCP/Azure), container security, and modern API architectures
