Your responsibilities will include monitoring security and infrastructure platforms, reviewing alerts and event logs, conducting initial triage, and escalating incidents in line with established procedures. You will investigate potential threats, support containment and remediation activities, and maintain accurate records within incident and service management systems. The role will also involve responding to operational issues, coordinating with infrastructure, application and third-party support teams, contributing to root-cause analysis, and providing timely updates throughout the incident lifecycle. You will help maintain operational runbooks, knowledge articles and reporting, while identifying opportunities to improve monitoring, automation, resilience and security controls. Participation in an agreed shift, on-call or out-of-hours rota may be required.
Applicants should have experience in a security operations, network operations, infrastructure support or service desk environment, with a sound understanding of incident management and operational security principles. Familiarity with SIEM, endpoint protection, vulnerability management, network monitoring, identity and access management, cloud services and ticketing platforms is desirable. You should be comfortable analysing logs and event data, following documented processes and working under pressure. Strong written and verbal communication, attention to detail and a commitment to continual learning are essential. Relevant certifications or practical experience in areas such as cybersecurity, IT service management, networking or cloud technologies would be advantageous.
