Incident commander (IC) jobs are positions of responsibility and authority to carry out emergency response plans. Incident commanders play a vital role in emergency response for natural disasters, acts of violence, and other emergencies, such as fires and bomb threats. More recently, the information technology (IT) sector adopted the IC role to manage disaster recovery and business continuity in the event of a computer systems failure or data breach. Whether in IT or other emergency response situations, as IC your duties include allocating resources, minimizing fallout, and supervising operations.
