Cyber Defense Incident Responder
We are seeking a Cyber Defense Incident Responder to help protect critical systems, applications, and data from evolving cyber threats. In this role, you will monitor, investigate, and respond to security incidents across enterprise environments, working closely with security operations, infrastructure, application, and risk teams. You will assess alerts, validate suspicious activity, determine scope and impact, contain threats, and support recovery efforts while maintaining clear and timely incident documentation.
Your responsibilities will include conducting investigations using security information and event management (SIEM), endpoint detection and response (EDR), network monitoring, identity, email, and cloud security tools. You will perform event correlation, malware and phishing analysis, threat hunting, and forensic triage; develop timelines and root-cause assessments; and recommend effective containment and remediation actions. You will also contribute to incident response procedures, playbooks, detection rules, and lessons-learned reviews, helping improve defensive capabilities and reduce the likelihood of repeat incidents. Participation in an on-call rotation may be required.
The successful candidate will have practical experience in cyber defense, security operations, digital forensics, or incident response, along with a strong understanding of common attack techniques, intrusion patterns, vulnerabilities, and security controls. Familiarity with Windows and Linux environments, cloud platforms, networking, authentication, scripting, and threat intelligence is desirable. You should be comfortable analyzing large volumes of technical information, communicating clearly with both technical and non-technical stakeholders, and making sound decisions under pressure. Industry certifications such as Security+, GCIH, GCFA, GCIA, CISSP, or equivalent experience are advantageous. A proactive mindset, strong attention to detail, discretion, and a commitment to continuous learning are essential.
