About the role
Think of this role as a technical utility player for Offensive Security Research. One day you will build containerized lab environments in Docker and GCP or wire up Python scripts to benchmark emerging offensive security tools and AI models. The next day you will collaborate with Senior Researchers to validate vulnerability findings, refine testing methodologies (Web, API, Cloud, IoT, and AI/LLM), and review specialized penetration testing reports for technical accuracy.
