Vulnerability Researchers / Security Researchers

About the Position

You are a hands-on Vulnerability Researcher or Security Researcher with experience discovering, analyzing, and exploiting vulnerabilities in complex systems. You have a strong understanding of reverse engineering, OS internals, and modern exploitation techniques, and can develop exploits, proof-of-concept code, and research tools to validate your findings. You are proactive, technically curious, and able to conduct vulnerability research independently in a full-time remote environment.

About the Project

We are a Barcelona-based R&D center looking for Vulnerability Researchers / Security Researchers to join our team. The role focuses on hands-on vulnerability research, including finding and exploiting vulnerabilities in complex systems such as browsers, kernels, mobile and desktop operating systems.
