Key Responsibilities for the Cybersecurity Engineer III

• Own complex cybersecurity incidents end-to-end with minimal guidance, including investigation, analysis, coordination, documentation, and post-incident improvements
• Perform advanced threat hunting and deep investigative work across EDR, SIEM, and cloud environments beyond alert-driven activity
• Analyze attacker behavior such as process execution, command-line activity, persistence techniques, and lateral movement
• Tune and improve detections across SIEM and EDR platforms to reduce false positives and improve signal quality
• Create, enhance, and maintain detection logic, rules, and queries based on threat intelligence, attacker behavior, and incident learnings
• Identify gaps in security posture, detection coverage, or response capabilities and recommend practical improvements
• Contribute to incident response strategy, operational maturity, and continuous process improvement initiatives
• Translate technical findings into clear, actionable recommendations for internal security and technology teams
• Serve as a technical escalation point during investigations and guide or mentor junior analysts or engineers as needed
• Partner closely with internal security, infrastructure, and cloud teams during incident response and improvement efforts

Required Qualifications for the Cybersecurity Engineer III

• 5-8+ years of relevant experience in incident response, threat hunting, detection engineering, or advanced SOC (Tier 3 / escalation-level) environments
• Strong hands-on experience with EDR platforms (e.g., CrowdStrike, Microsoft Defender) in investigative and response scenarios
• Experience operating and tuning detections within SIEM platforms such as Splunk or Microsoft Sentinel
• Demonstrated ability to independently investigate complex threats, including malware, phishing, account compromise, and advanced attacker activity
• Strong understanding of how EDR, SIEM, cloud environments, and infrastructure work together from a security perspective
• Experience working in Azure and/or AWS environments
• Ability to clearly explain why activity is malicious and communicate impact, risk, and remediation recommendations to both technical and non-technical stakeholders
