Senior Security Analyst (MDR)
We are seeking a Senior Security Analyst (MDR) to join a specialist security operations function responsible for protecting customers against evolving cyber threats. In this role, you will monitor and investigate security events across multiple environments, providing expert analysis, timely response and clear communication throughout the incident lifecycle. You will act as an escalation point for complex alerts and support the continuous improvement of detection and response capabilities.
Your responsibilities will include analysing alerts from SIEM, EDR, network, cloud and other security technologies; conducting threat hunting and proactive investigation; validating indicators of compromise; and performing detailed incident triage, containment and remediation. You will develop and tune detection use cases, contribute to playbooks and operational procedures, and produce accurate technical reports for internal and customer stakeholders. The role will also involve mentoring junior analysts, reviewing investigation quality, supporting shift handovers and helping to identify trends, control gaps and opportunities to improve monitoring coverage. You may occasionally contribute to incident response exercises, vulnerability investigations and post-incident reviews.
Applicants should have substantial experience in a security operations, managed detection and response, incident response or threat hunting environment, together with strong knowledge of security monitoring principles and attack techniques. Practical experience with SIEM and EDR platforms, log analysis, network traffic, endpoint telemetry and cloud security is essential. You should be confident using frameworks such as MITRE ATT&CK and applying structured investigation methodologies. Familiarity with scripting, automation, detection engineering or malware analysis would be advantageous. Strong analytical, written and verbal communication skills are required, along with the ability to prioritise incidents, make sound decisions under pressure and explain technical findings to both technical and non-technical audiences. Relevant industry certifications or equivalent professional experience are welcomed.
