About the role
As a Cybersecurity Red Teamer, you will evaluate whether AI models can be manipulated into generating functional malware, viable exploit code, attack tooling, or step-by-step operational guidance that could give a threat actor meaningful assistance in carrying out cyberattacks. Your job is to find the gaps between what a model’s safety guardrails are intended to block and what a skilled adversary can actually extract.
What they're looking for
- Professional experience in offensive security, penetration testing, red teaming, vulnerability research, malware analysis, threat intelligence, or incident response
- Ability to read, write, and evaluate code in languages commonly used for offensive tooling, such as Python, PowerShell, Bash, C/C++, or JavaScript
- Understanding of common attack frameworks, techniques, and procedures, including MITRE ATT&CK and OWASP
- Ability to assess the functional correctness and real-world exploitability of model-generated technical output
- Strong hands-on experience using multiple LLMs, such as ChatGPT, Claude, Gemini, or open-source models
- Creative and adversarial problem-solving skills
