Your role in the team

Network Operations: You monitor the network and system infrastructures of our clients and assess incoming reports and disruptions. You analyze technical issues based on defined processes, narrow down possible causes, and initiate appropriate measures. In first-level support, you handle incidents and service requests, prioritize disruptions according to their impact, and ensure a structured escalation to the relevant specialist departments. At the same time, you maintain direct communication with our clients, communicate professionally and transparently, and keep them informed about the status of the processing and the next steps.
Security Operations - Level 1: You monitor and handle security alerts from SIEM, EDR, network, and other security systems. You evaluate and prioritize alerts based on clearly defined processes and runbooks, add relevant contextual information such as affected systems, user accounts, IP addresses, or timeframes, and distinguish between false positives, suspicious activities, and potential security incidents. You document your analysis results in a traceable manner and prepare them for further processing. Confirmed or unclear security events are escalated to the second-level SOC or the incident response team. Additionally, you support defined initial measures, such as blocking user accounts, always within the framework of established procedures.
Collaboration & Documentation: You document all activities comprehensively and transparently in the ticketing system, working closely with experienced network, system, security, and incident response specialists. Through structured handovers, you ensure a smooth flow of information between layers and contribute significantly to high service and operational quality.
