Anyone AI is recruiting experienced Application Security Engineers and Vulnerability Researchers for a specialized project focused on reviewing real-world software vulnerabilities, CVE reproductions, remediation approaches, and exploit verification environments.

We’re looking for security professionals with hands-on experience in penetration testing, vulnerability research, or application security who can determine whether vulnerabilities are reproduced accurately, fixes address the actual root cause, and security tests reliably demonstrate that an exploit has been mitigated.

What You’ll Work On

You’ll review technical security tasks involving:

CVE vulnerability reproduction
Exploit proof-of-concepts
Vulnerability remediation and secure coding
Application security testing
Docker-based vulnerability labs
Exploit verification scripts
Security regression testing
CVSS, CWE, and vulnerability classification
Environment and configuration analysis
Edge cases and alternative attack paths

A key part of the role is determining whether a vulnerability environment accurately recreates the original attack conditions and whether a proposed fix genuinely eliminates the vulnerability without breaking legitimate functionality.

What We’re Looking For

3+ years of hands-on experience in application security, penetration testing, or vulnerability research
Strong understanding of CVE, CVSS, CWE, and common vulnerability classes
Experience identifying and remediating vulnerabilities such as:
- SQL injection
- Command injection
- SSRF
- Deserialization vulnerabilities
- Buffer overflows
- Privilege escalation
- Access control issues
- Security misconfigurations
Strong understanding of secure coding and vulnerability remediation
Experience reviewing or developing exploit proof-of-concepts
Experience validating whether security fixes address the root cause rather than only the immediate exploit
Proficiency with Docker and Docker Compose
Ability to provide clear, technically rigorous written feedback

What You’ll Be Responsible For

Reviewing CVE reproduction environments for technical accuracy
Determining whether vulnerabilities faithfully reproduce the original attack vector and impact
Evaluating proposed security fixes and remediation strategies
Reviewing test suites that verify both:
- Normal application functionality remains intact
- The original exploit no longer succeeds
Identifying incomplete fixes and alternative exploitation paths
Reviewing Docker environments for correct software versions, services, networking, and configuration
Detecting potential regressions or new vulnerabilities introduced by a fix
Providing recommendations for improving vulnerability reproductions, fixes, and verification logic

Nice to Have

OSCP, GPEN, GWAPT , or equivalent security certification
Experience with responsible vulnerability disclosure or CVE reporting
Experience maintaining exploit proof-of-concept code
Experience writing automated security tests using tools such as:
- Python
- requests
- curl
- pwntools
- Custom exploit harnesses
DevSecOps experience
Familiarity with SAST, DAST, and CI/CD security tooling
Experience developing or reviewing cybersecurity assessments or technical security challenges
Experience with AI evaluation, RLHF, or technical data projects

Engagement

Work Type: Remote
Engagement: Part-time, project-based consulting
Focus: Application security, vulnerability research, CVE reproduction, and remediation

This role is ideal for security engineers who enjoy understanding how vulnerabilities actually work, reproducing exploits in controlled environments, evaluating security fixes, and identifying subtle gaps that traditional testing may miss.

Argentina, Uruguay, Chile, Ecuador, Portugal, Mexico, Colombia, Spain, Brazil
