About the Role:

CrowdStrike Counter Adversary Operations is seeking a motivated malware reverse engineer with excellent technical skills to research advanced cybercriminal attacks. Our Technical Analysis Cell (TAC) is at the forefront of CrowdStrike’s mission against state-sponsored adversaries and criminal actors. We combine intelligence analysis with deep-dive reverse engineering and malicious code analysis, in addition to building and using automation systems to deliver actionable indicators and operational insights. CrowdStrike is uniquely positioned to leverage data from a multitude of sources, including our proprietary telemetry, our large internal malware corpus, and our custom-built analysis pipeline. We foster an environment of respectful, passionate camaraderie and collaboration between researchers who enjoy the fast-paced nature of our work.

This highly technical position on the TAC eCrime team serves an important role in conducting research, increasing our coverage of the global threat landscape, contributing to the continuous tracking of criminal adversary groups, and ultimately developing finished intelligence products that provide a decision advantage to customers.

We are ideally looking for a seasoned specialist in the tracking of eCrime actors, their tooling, and their TTPs.
