Configure monitoring for anomaly detection and automated response across cloud and hybrid environments. Coordinate and investigate information security incidents and lead technical incident response. Analyse large datasets and security logs from network, infrastructure and application sources. Develop scripts and automation for detection, enrichment and response (SOAR). Support the definition and control of access rights to information and critical systems. Evaluate and help implement new detection, identity and monitoring technologies. What you’ll need to succeed: Bachelor’s or Master’s degree in Information Technology, Computer Science, Cybersecurity or a related field.
