• Act as a senior escalation point within the SOC, providing technical expertise on high-priority security events, breaches and emerging threats.
• Proactively hunt for threats across customer environments using Microsoft security technologies, identifying risks before they become incidents.
• Drive continuous improvement in detection capabilities by enhancing analytics, automation, threat intelligence and investigation processes.
• Assess customer security posture, uncover vulnerabilities and provide practical recommendations to reduce risk across cloud, identity, endpoint and network environments.
• Mentor and support SOC analysts, sharing knowledge, developing best practices and helping raise the overall capability of the team.
• Build trusted relationships with customers, clearly communicating security risks, remediation plans and technical insights while contributing to the ongoing evolution of the SOC service.

• Deep expertise across the Microsoft security ecosystem, including Sentinel, Defender, Entra, Azure and Intune, with the ability to turn insight into action.
• Strong threat hunting, detection engineering and investigation skills, using tools such as Kusto Query Language (KQL) and security automation to identify and respond to emerging threats.
• Solid understanding of modern security architecture, covering cloud, identity, endpoint and network security, with the ability to assess risk and recommend improvements.
• Confident communicator who can translate complex technical issues into clear, practical recommendations for both technical and non-technical audiences.
• Natural mentor and technical leader, with experience supporting the development of other analysts and driving best practice across security operations teams.
