About the Role: The Cybersecurity Incident Response (IR) Commander is the technical and operational authority for ISA Cybersecurity's Digital Forensics & Incident Response (DFIR) function and holds expert-level command of the Security Incident Response (SIR) service during client engagements. The role is structured as a Subject Matter Expert and Incident Commander rather than a line-management position: technical authority, judgment under pressure, and external-grade SME presence are the primary contributions. The IR Commander leads the Response side of ISA's Protect-Detect-Respond operating model through influence, process and playbook ownership, and direct command on every Emergency and IR Retainer engagement. People-leadership behaviors including coaching analysts, championing career pathways, and modelling composure under stress are valued and expected to grow over time, but formal direct reports are not a requirement of the role at hire. Development and ongoing evolution of the Incident Response program is subject to the final authority of the Senior Director, DFIR Services who provides strategic direction and ultimate accountability for the program's scope, structure, and priorities. This role reports to the Senior Director, DFIR Services. The successful candidate will have extensive experience in personally commanding and leading ransomware, business email compromise, data exfiltration, and complex multi-vector engagements, and will be recognized externally as a subject-matter expert in incident response and digital forensics.
