What success looks like in this role:

• Define an end-to-end, layered (Defense-in-depth) cybersecurity architecture across cloud, SIEM/SOC, MDR, CTEM,CRV,SNA, IAM, network, endpoint, and data domains
• Establish reference architectures, design patterns, and reusable security blueprints that delivery teams can adopt rather than rebuild
• Map capabilities to business risk, maintain a forward-looking architecture roadmap, and rationalize tooling to reduce complexity and tool sprawl

2.  Threat Modeling & Threat-Informed Defense

• Establish enterprise threat modeling practices (e.g. STRIDE, attack trees, MITRE ATT&CK) and embed them early in the design lifecycle (security-by-design)
• Identify trust boundaries, attack paths, and data flows; translate identified threats into prioritized, actionable controls
• Extend threat modeling to AI/LLM and automation systems, addressing risks such as prompt injection, model abuse, and data poisoning

3.  Zero Trust Architecture

• Define and drive the Zero Trust strategy and roadmap across identity, devices, network, applications, and data
• Apply least-privilege access, micro-segmentation, strong authentication/MFA, conditional access, and continuous verification
• Treat identity as the primary control plane, aligning Zero Trust closely with IAM and Secure Network Access

4.  Identity & Access Management (IAM)

• Architect IAM using Microsoft Entra - authentication and authorization, RBAC/ABAC, conditional access, and the identity lifecycle (joiner / mover / leaver)
• Design privileged access management (PAM/PIM), access governance and reviews, and protection of workload and non-human identities
• Ensure IAM underpins Zero Trust as the enterprise’s primary security perimeter

5.  Detection, MDR & SOC Modernization

• Architect a proactive, predictive, and increasingly autonomous Security Operations Center (SOC), including a defined detection engineering lifecycle (detection-as-code, ATT&CK coverage mapping, tuning to reduce false positives) and threat hunting
• Integrate Managed Detection and Response (MDR) - align 24/7 detection and response, define the shared-responsibility model, and connect MDR telemetry and response actions into the internal SIEM/SOAR
• Drive measurable improvements in mean time to detect and respond (MTTD/MTTR)

6.  Continuous Threat Exposure Management (CTEM)

• Establish a CTEM program across the five stages - scoping, discovery, prioritization, validation, and mobilization
• Prioritize exposures by real exploitability and business impact (beyond raw CVE counts), incorporating breach-and-attack simulation and attack-path analysis
• Drive continuous, evidence-based exposure reduction and remediation

7.  Secure Network Access

• Architect Secure Network Access using Zero Trust Network Access (ZTNA) and SASE/SSE principles, replacing legacy flat-network and VPN models
• Design network segmentation / micro-segmentation and east-west visibility, integrating Network Detection and Response (NDR)
• Secure hybrid, remote, and third-party access for users and workloads

8.  Cyber Resilience & Recovery (Cyber Recovery Vault)

• Design cyber resilience and recovery architecture, including an isolated, immutable Cyber Recovery Vault (air-gapped) and clean-room recovery capability
• Architect recovery from ransomware and destructive attacks, integrate with backup/DR, and define recovery objectives (RPO/RTO) and data-integrity validation
• Establish regular recovery testing and align the design with operational resilience requirements

9.  AI & GenAI-Enabled Security

• Design AI-driven detection and response; implement Security Copilot and agentic systems for automated triage, investigation, and analyst augmentation, progressing toward an autonomous SOC
• Apply Generative AI responsibly - establish governance and guardrails for GenAI risks (prompt injection, data leakage, hallucination, model and data security), with human-in-the-loop for high-impact actions
• Enable adaptive and self-healing security systems

10.  AI-Enabled Automation & Platform Engineering

• Drive an automation-first approach - SOAR playbooks, agentic and AI-enabled automation, and self-healing workflows, targeting 30–50% automation enablement
• Architect platforms using Microsoft Sentinel, Defender, Entra, and Purview; build reusable modules for detection, response, and automation
• Apply engineering practices including infrastructure-as-code, detection-as-code, version control, and testing

11.  Innovation Leadership

• Partner with Solutions Development to lead PoCs and emerging-technology adoption; translate new technology into scalable solutions
• Work with Delivery to understand real-world issues, ideate, and create reusable assets

12.  Governance & Compliance

• Align architecture with ISO 27001 and NIST (CSF / 800-53) standards, and embed security-by-design and compliance-as-code
• Support audits and evidence collection; balance compliance requirements with risk-based exposure reduction

13.  Collaboration & Stakeholder Influence

• Work closely with delivery, engineering, and business teams
• Act as a trusted technical advisor across the organization

• #LI-SK2

You will be successful in this role if you have:

• Bachelor’s or Master’s degree in a relevant field
• 12–18 years of cybersecurity experience, including hands-on architecture and engineering
• Deep expertise in the Microsoft Security stack (Sentinel, Defender, Entra, Purview) and cloud security
• Demonstrated experience across Zero Trust, IAM, MDR/SOC, CTEM, Secure Network Access (ZTNA/SASE), and cyber resilience and recovery
• Strong threat Modeling and threat-informed Defense experience
• Strong AI/ML cybersecurity exposure, including GenAI / agentic security and AI risk governance
• Proven hands-on capability - detection engineering, automation, scripting, and building PoCs
