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)
