Security Operations Engineer Security Analyst Host & Network Forensics Threat Hunting Ai @Carnival UK (P&O Cruises & Cunard)
Southampton, GB
Owning SIEM operations end to end, I lead the deployment, configuration, tuning, maintenance, and troubleshooting of enterprise security monitoring platforms. I oversee continuous monitoring and advanced threat detection across SIEM, IDS/IPS, and endpoint tools(Web Proxy, Email Proxy,EDR and Vulnerability Management), proactively hunting threats and reducing exposure to advanced persistent attacks.I drive SOC efficiency through automation, using Python, PowerShell, and Bash to streamline alert handling, data enrichment, reporting, and operational workflows. I pragmatically integrate AI into daily security operations to improve alert triage, phishing analysis, and analyst collaboration, delivering measurable reductions in noise while maintaining trust and control.Alongside operations, I lead security and AI assurance testing for cloud and hybrid environments, strengthening detection accuracy, automated response reliability, and overall SOC readiness.Key contributions: Owned full SIEM lifecycle management, improving detection quality and operational stability. Automated SOC workflows using Python, PowerShell, and Bash, significantly reducing manual analyst effort. Implemented AI-assisted alert triage and phishing analysis, lowering false positives and accelerating response times. Led security and AI assurance testing across cloud-hosted and hybrid environments. Validated AWS/Azure telemetry pipelines including CloudTrail, VPC FlowLogs, and Log Analytics to ensure end-to-end visibility. Conducted API and integration testing for security tooling, improving reliability and performance baselines. Executed risk-driven testing for ransomware, data centre outages, and loss-of-communications scenarios. Delivered executive-level assessments of third-party security tools and enterprise risk posture. Maintained continuous SOC readiness through health checks, monitoring validation, and process optimisation.
