SIEM Security Engineer
We are seeking a skilled SIEM Security Engineer to support the monitoring, detection, and response capabilities of a dynamic security operations environment. In this role, you will design, maintain, and optimise Security Information and Event Management (SIEM) platforms, ensuring that security telemetry is collected, normalised, and analysed effectively across cloud, infrastructure, application, and endpoint environments. You will work closely with security analysts, infrastructure teams, and application owners to improve visibility and strengthen overall cyber resilience.
Your responsibilities will include developing and tuning correlation rules, detection use cases, dashboards, alerts, and automated workflows. You will investigate complex security events, support incident response activities, and help identify indicators of compromise, attack patterns, and emerging threats. You will also manage log source onboarding, troubleshoot data quality and ingestion issues, and establish appropriate retention, access, and monitoring standards. The role will involve contributing to threat hunting, vulnerability investigations, security reporting, and continuous improvement initiatives, while documenting technical procedures and maintaining accurate operational records.
The successful candidate will have practical experience working with SIEM technologies such as Microsoft Sentinel, Splunk, IBM QRadar, or comparable platforms, together with a strong understanding of security monitoring principles and incident management processes. Knowledge of log analysis, detection engineering, threat intelligence, MITRE ATT&CK, network protocols, operating systems, cloud services, and scripting languages such as Python or PowerShell is highly desirable. Relevant certifications, including Security+, CySA+, GCIA, GCIH, or equivalent, would be advantageous. You should be analytical, collaborative, and comfortable communicating technical findings to both technical and non-technical stakeholders. The position may involve participation in an on-call or out-of-hours support rota.
