This position works in our Technology team and serves as a Tier 1 security operations analyst, monitoring and triaging security alerts across ARI's enterprise IT and OT environments. The role executes documented playbooks, escalates higher-severity incidents to senior security staff, and contributes to the maturation of ARI's detection and response capability. The SOC Analyst I is the first line of detection and response for ARI's IT estate and works in coordination with the OT Security Engineer, who owns the OT side, and with ARI's external MSSP. This position will report to Head of Remote Workforce Strategy and the Director of Technology. This is a hybrid position, with most of the time spent working from home but with office attendance from time to time, as needed.
