Security Researcher

We believe that software is the foundation of modern civilization, yet vulnerabilities threaten its integrity, security, and resilience. Strix is on a mission to solve security. Strix builds autonomous AI penetration testing agents that think like attackers: discovering, validating, and helping fix real vulnerabilities across live applications, codebases, and infrastructure, continuously, not once a year. We are looking for strong technical people who want to work at the intersection of AI, security, and infrastructure.
