• Design, deploy, and operate a layered deception fabric across on-premises, hybrid, and multi-cloud environments
• Act as the technical authority for deception engineering and Microsoft Defender XDR across the enterprise
• Lead the design, implementation, and optimisation of Microsoft Defender XDR across endpoint, identity, email, and cloud-app workloads
• Integrate deception signals into Defender XDR and Microsoft Sentinel as high-fidelity detections
• Define and enforce a unified detection and response strategy across the Microsoft security stack
• Lead the design and implementation of Microsoft Purview Data Loss Prevention policies
• Define and enforce data protection controls to prevent unauthorised data exfiltration and misuse
• Use Microsoft Insider Risk Management to detect risky user behaviour, including data leaks, policy violations, and insider threats
• Correlate DLP, IRM, and identity signals with Microsoft Defender XDR to provide unified incident context
• Collaborate with Risk, Compliance, and Legal teams to align DLP and insider risk controls with regulatory and business requirements
• Optimise detection use cases combining identity, data, and behavioural analytics
• Extend deception and Defender-style detection capabilities across AWS, GCP, and OCI
• Ensure consistent detection, deception, and response coverage across hybrid and multi-cloud environments
• Contribute to automation of deception deployment, detection, investigation, and response workflows using Microsoft Sentinel SOAR, Logic Apps, and Microsoft Security Copilot
• Define KPIs and metrics for deception engagement, detection coverage, and response maturity
• Improve detection, hunting, and deception capabilities in line with emerging threats and adversary tradecraft
• Lead and grow a team of Defender XDR and Deception Engineers, setting technical direction, standards, and delivery priorities
• Partner with SOC, CTI, Identity, Cloud, and Engineering teams to embed deception and Defender XDR detection into enterprise platforms
• Mentor deception engineers, detection engineers, threat hunters, and SOC analysts
• Communicate deception strategy, detection coverage, residual risk, and security improvements to senior stakeholders
• Lead incident response across identity, endpoint, email, and cloud domains

• Hands-on experience with open-source and commercial deception and honeypot platforms
• Advanced KQL for detection engineering and threat hunting at scale
• Experience with detection-as-code, CI/CD of detection content, and security content management
• Strong knowledge of adversary tradecraft and MITRE ATT&CK, MITRE Engage, MITRE D3FEND, and the cyber kill chain
• Experience leveraging Agentic AI, Microsoft Security Copilot, or AI/ML in security operations
• Proven experience designing and operating enterprise cyber deception programmes at scale
• Extensive hands-on experience operating and engineering Microsoft Defender XDR in large enterprises
• Deep expertise across Microsoft Defender for Identity, Microsoft Sentinel, Microsoft Security Copilot, Microsoft Defender for Cloud Apps, and Defender for Cloud
• Strong scripting and automation experience with PowerShell, Python, or equivalent
