• Triage and investigate alerts to determine severity, business impact, and appropriate response actions.
• Escalate confirmed or suspected incidents in line with SOC procedures and incident response playbooks.
• Analyse logs, endpoint telemetry, identity events, and cloud activity to identify suspicious behaviour and potential compromise.

• Contribute to the continuous improvement of detection logic, alert quality, and SOC operational processes.

Security Tooling & Operational Support

• Use Microsoft Sentinel, Microsoft Defender XDR, SentinelOne, vulnerability management platforms, and other security tools to support daily SOC operations.
• Assist with alert tuning by identifying false positives, recurring noise, and opportunities to improve detection accuracy.
• Maintain clear investigation notes, incident records, and operational documentation.
• Support vulnerability monitoring, validation, and escalation where findings present operational or compliance risk.

Governance, Compliance & Reporting

• Support SOC activities that help maintain compliance with PCI DSS and other regulatory requirements.
• Produce clear, accurate, and timely updates on incidents, investigations, and operational security issues.
• Maintain audit-ready records relating to alerts, investigations, incidents, and response actions.
• Support internal and external audit activities by providing evidence and operational context where required.

Key Deliverables

• Security alerts triaged, investigated, and escalated within agreed operational procedures.
• Incident records and investigation notes maintained to a consistent and audit-ready standard.
• Confirmed threats escalated promptly with clear evidence, impact assessment, and recommended next steps.
• False positives, recurring alert noise, and detection gaps identified and fed into continuous improvement activity.
• Security monitoring, vulnerability, and incident response activities supported in line with SOC priorities.
• Improved visibility, response consistency, and operational discipline across SOC activities.

Who you are

• Experience triaging and investigating security alerts in a SOC or security operations environment.
• Good understanding of common cyber threats, attack techniques, endpoint activity, identity events, and network indicators.
• Hands-on experience using SIEM, EDR, XDR, or similar security monitoring platforms.
• Ability to analyse logs, correlate events, and document findings clearly.
• Understanding of incident response processes, escalation routes, and evidence handling.
• Awareness of PCI DSS, regulatory expectations, or working in a controlled operational environment.
