Cyber Defence Operations Engineer Location: Dublin Type: Full-Time | €60,000 - €75,000 A major technology-led organisation with large-scale digital platforms is expanding its security function in Dublin. They're investing heavily in improving visibility, strengthening detection, and maturing their response playbooks and need someone to support this evolution across day-to-day defensive operations. What You'll Be Doing Handle escalations from monitoring teams and dig into suspicious activity across cloud, identity, and endpoint layers. Perform deeper investigations into unusual behaviour and assist with containment actions. Help tune detection rules, reduce false positives, and support building new alert logic. Take part in proactive hunts to uncover stealthy or emerging threats. Assist in automating manual response steps and improving workflows. Contribute to after-action reviews and maturing runbooks and processes. Work closely with engineering, infrastructure, and cloud teams to tighten controls. What You'll Bring 2-4 years' experience in SOC analysis, cyber defence, threat monitoring, or a similar security operations role. Comfortable reviewing telemetry from SIEM, EDR, identity logs, and cloud platforms. Knowledge of attacker techniques and behaviour frameworks such as MITRE ATT&CK. Some exposure to Python, Bash, or PowerShell for basic automation. Strong analytical and investigative mindset with clear communication skills.
