CAREER_NODE_PROFILEDetection Engineer
"A Detection Engineer is a specialized cybersecurity professional responsible for designing, testing, and deploying logic to identify malicious activity within an organization's network. Utilizing frameworks like MITRE ATT&CK and methodologies such as Detection-as-Code, they continuously analyze logs, tune SIEM rules, and refine EDR alerts to minimize false positives while maximizing threat visibility. This role bridges the gap between threat intelligence and security operations, ensuring enterprise defenses adapt dynamically to emerging cyber threats."
The Detection Engineer is a highly specialized cybersecurity architect embedded within Security Operations (SecOps) or Threat Intelligence teams. This role is strictly focused on designing, implementing, and continuously tuning threat detection logic across various telemetry sources, including SIEM, EDR, and cloud infrastructure. Operating at the intersection of threat intelligence, incident response, and software engineering, Detection Engineers utilize methodologies such as Detection-as-Code (DaC) to lifecycle rules using Sigma, YARA, and Python. Their primary objective is to maximize the efficacy of security alerts by mapping adversarial behaviors to the MITRE ATT&CK framework, minimizing false positives, and ensuring high-fidelity, actionable alerts for the Security Operations Center (SOC).
