Security Researcher

About Strix

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.

About this role

We're looking for a Security Researcher to push the frontier of what our AI agents can find. You will hunt for real vulnerabilities, turn your offensive-security expertise into agent skills, benchmarks, and detection strategies, and validate that Strix finds what matters in real-world targets.

You're excited about this role because you will…

• Discover and exploit vulnerabilities in web applications, APIs, cloud infrastructure, and open-source software

• Encode offensive-security techniques into agent behaviors, tools, and playbooks that scale your expertise

• Build and curate vulnerable environments and benchmarks that measure real agent capability

• Analyze agent findings, separate signal from noise, and drive the false-positive rate toward zero

Qualifications

• 3+ years of hands-on offensive security experience (penetration testing, red teaming, bug bounty, or vulnerability research)

• Deep understanding of web application security, exploitation techniques, and modern attack surfaces

• Programming experience in Python or similar; comfort building your own tooling

• CVEs, published research, CTF results, or a strong bug bounty track record are a plus

• A tendency to leave things in a better way than you found them

What we offer

• Competitive salary with meaningful equity

• Health, vision, and dental insurance

• Office lunch and dinner (when working from our New York office)
