About the Role

Here at CrowdStrike an international team of researchers, engineers and malware analysts develop a high-end malware analysis framework with an agile and open architecture called Falcon Sandbox. Our system processes thousands of executable files, scripts and documents and “detonates” them fully automated in an isolated environment.

This allows reliable detection of unknown threats and zero-day exploits in the wild.
