We’ve earned numerous honors and top rankings for our technology, organization and people – clearly confirming our industry leadership and our special culture driving it.

The opportunity: Our CrowdStrike Data Science Machine Learning Operations and Response Team is looking for a Sr Threat Analyst who is both customer- and team-focused. This role will include both response and pro-active aspects. This role will be perfect for anyone who has experience involving detections and/or reverse engineering. The primary responsibility of this role will be to analyze breaches and killchains involving malware and detections. This team is focused on improving detection capability and efficiency through analysis of malware or other threat detections impacting our customer base.

Experience with security detections by machine learning models is a plus. Bring your passion for helping internal partners resolve questions about detections of potentially malicious activity by machine learning and our detection platform. Our goal for the team is to both help internal teams respond to customer-inquiries about threat detection and to provide information about the effects of our detections into the Data Science organization - including detection efficacy and managing false positive detections.

This role will work most closely with internal teams such as Falcon Complete, Falcon Overwatch, Data Scientists and the Malware Research Center in Data Science.

What You'll Do

• Lead efforts to review and refine product detections to ensure they meet and exceed company standards.
• Identify and drive improvements in false positive detection management through deep technical analysis and process enhancements.
• Analyze files and killchains across different platforms (Linux, public Clouds, Mac, and Windows) to assess legitimacy and identify malicious behaviors.
• Act as a senior escalation point for internal teams regarding complex customer threat detections.
• Collaborate cross-functionally with threat research, engineering, and incident response teams to drive detection efficacy.

What You'll Need

• Deep technical expertise in Linux or Mac operating systems, including internals and threat behaviors.
• Demonstrated subject matter expertise in public Cloud environments, preferably AWS or Azure.
• Strong background in reverse engineering malware and malware operations.
• Solid proficiency in Python, with additional experience in other scripting/programming languages a plus.
• In-depth understanding of binary analysis, including file attributes, imports/exports, and common packing techniques.
• Advanced analytical skills, including practical experience with threat research, intelligence collection, and structured analysis methodologies.
• Strong grasp of threat/risk assessment and threat management framework.
