• Develop and optimise security detections (Sentinel, KQL, YARA).
• Manage log sources, ingestion pipelines, and monitoring infrastructure.
• Conduct threat hunting and analysis to identify emerging risks.
• Lead and contribute to incident investigations, including post-mortem analysis and remediation actions.

Vulnerability & Risk Management

• Identify, track, and remediate vulnerabilities across cloud, endpoint, and infrastructure.
• Implement controls from security assessments, audits, and architecture reviews.
• Support third-party risk assessments and vendor due diligence.

Governance, Documentation & Projects

• Maintain documentation of security standards, runbooks, and procedures.
• Participate in security-related projects and lead implementation of new security solutions.

Required Qualifications

• 3+ years in security engineering or security operations, ideally in cloud-first environments.
• Strong understanding of cloud security architecture with hands-on experience securing cloud infrastructure and services.
• Hands-on experience with the Azure security stack, including Microsoft Defender for Cloud (recommendations, alerts, Secure Score), Azure Policy, and related security tooling.
• Proficiency with SIEM platforms (Azure Sentinel preferred), developing detections and alerts, tuning rules, and investigating incidents.
• Proven incident response capability including triage, investigation, containment, eradication, and recovery.
• Practical experience integrating security into software and system development lifecycles.
• Experience with endpoint security solutions and MDM/EMM tools.
• Experience securing containerised environments (Kubernetes) and CI/CD pipelines.
• Proficiency in scripting and automation (PowerShell, Python, KQL, Bicep).
• Strong understanding of network security — protocols, firewalls, IDS/IPS, WAFs, and infrastructure hardening.
• Familiarity with incident response frameworks (NIST, SANS).
• Experience configuring and using cloud-native security logging, monitoring, and detection services.
• In-depth knowledge of security principles, attack vectors (OWASP Top 10, MITRE ATT&CK), and the threat landscape.
