About Product Group:
The Counter Adversary Operations (CAO) Team is a first-of-its kind team that brings together CrowdStrike Falcon® Intelligence and the CrowdStrike® Falcon OverWatch™ threat hunting team to disrupt today’s adversaries and ultimately raise their cost of doing business. Both threat hunting and intelligence operations are essential to detect, disrupt and stop today’s adversaries.
About the Role:
Join our Counter Adversary Operations team as a Cloud Engineer and architect the infrastructure powering CrowdStrike's next-generation malware analysis ecosystem. You'll build and scale the cloud backbone for four cutting-edge products that are redefining threat detection: Falcon Sandbox's kernel-level evasion-resistant analysis environments, QuickScan Pro's high-throughput pipelines processing millions of files annually, Falcon MalQuery's multi-petabyte search infrastructure enabling real-time queries across 3.5+ billion malware samples, and our intelligent Malware Analysis Agent that orchestrates sandboxes, YARA engines, and search capabilities to deliver instant attribution and automated rule generation. This role combines massive scale engineering challenges—from real-time processing of petabyte-scale datasets to coordinating complex distributed analysis workflows—with direct mission impact, as your infrastructure enables security analysts worldwide to stay ahead of the most sophisticated adversaries. You'll work alongside a collaborative team of security researchers and engineers who are passionate about building tools that don't just detect threats, but fundamentally change how the industry approaches malware analysis and threat intelligence.
