Anyone AI

Application Security Engineer – CVE & Vulnerability Research

Argentina

  • Mid level
  • Contract
  • Remote

About the role

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.
