Ready to join a mission that matters? The future of cybersecurity starts with you.

The Threat Analyst joins the Emerging Threats and Security Validation team within the CrowdStrike Malware Research Center (MRC). This team plays a critical role in understanding today's threat landscape, identifying gaps in Falcon's detection capabilities, and helping improve CrowdStrike's protection through threat research, automation, AI, and machine learning. Working closely with Threat Research, Engineering, Data Science, and Red Team teams, you'll investigate emerging threats, validate detection coverage, and translate technical research into product improvements that better protect our customers. This is an excellent opportunity for someone who enjoys solving complex technical problems while making a direct impact on our products.

Research and analyse emerging malware and cyber threats to understand how they impact our customers. Investigate malware across the full attack lifecycle (adversary kill chain) to ensure Falcon detects and stops threats at every stage. Distinguish genuine threats from background noise by analysing data from multiple internal and external sources. Validate and improve CrowdStrike's detection capabilities by identifying gaps and working with engineering teams to strengthen our protections. Support external security testing and certification programmes (such as AV-Test, AV-Comparatives, and SE Labs) by analysing test results and helping address any missed detections. Respond to newly discovered threats by performing technical investigations and recommending the best approach for detection and prevention. Partner with Threat Research, Engineering, Red Team, and Machine Learning teams to translate research into product improvements. Help design and improve automation that reduces manual effort and accelerates threat analysis. Communicate technical findings clearly to engineering and response teams to enable faster and more effective action. Contribute to the continuous evolution of Falcon by combining malware research, automation, AI, and machine learning to improve customer protection.

Bachelor's or Master's degree in Computer Science or a related field. 4+ years of experience in threat research with a focus on malware analysis. Experience reverse engineering file-based malware, exploits, and other attack techniques. Industry certifications such as GIAC Reverse Engineering Malware (GREM) are desirable. Strong understanding of disassembly and structured programming principles. Deep knowledge of at least one major operating system and its internals to support behaviour-based analysis. Strong understanding of the adversary kill chain and attacker behaviour, with experience
