Security Engineer - Microsoft Sentinel & Defender XDR (Various levels)
We are seeking Security Engineers at various levels to design, implement, and improve cloud-based security monitoring and incident response capabilities using Microsoft Sentinel and Microsoft Defender XDR. You will help protect critical systems, applications, identities, and data by developing effective detection, investigation, and response solutions across the Microsoft security ecosystem. The role offers opportunities to work on both operational security and strategic improvement initiatives in a collaborative, technically focused environment.
Responsibilities may include onboarding and normalising data sources in Microsoft Sentinel; developing and tuning analytics rules, automation rules, workbooks, dashboards, and playbooks; investigating alerts and incidents across Microsoft Defender XDR; and supporting threat hunting, vulnerability remediation, and security investigations. You will contribute to incident response processes, identify opportunities to reduce false positives, document technical procedures, and provide clear recommendations to technical and non-technical stakeholders. Depending on experience, you may also lead security engineering projects, mentor colleagues, establish monitoring standards, and help shape the wider security operations roadmap.
We are looking for candidates with practical experience in security engineering, security operations, threat detection, or incident response, together with an understanding of Microsoft Sentinel, Defender for Endpoint, Defender for Identity, Defender for Office 365, and Defender for Cloud Apps. Familiarity with Kusto Query Language (KQL), Microsoft Entra ID, cloud platforms, logging architectures, and security automation is highly desirable. Experience with scripting, particularly PowerShell, and knowledge of frameworks such as MITRE ATT&CK will be advantageous. Strong analytical, communication, and problem-solving skills are essential. Applications are welcomed from early-career professionals with relevant technical foundations as well as experienced engineers able to provide technical leadership. Relevant Microsoft, cloud, or cyber security certifications are beneficial but not essential.
