Head of Security Architecture, Managing Director

Who we are looking forThe Head of Security Architecture, Managing Director is a senior cybersecurity leader responsible for establishing and scaling a secure-by-design operating model that embeds cybersecurity requirements directly into technology design, engineering, and delivery processes across the enterprise.

The position is accountable for establishing the standards, baselines, reference architectures, security patterns, and threat-informed design practices that enable consistent, scalable, and resilient security outcomes across cloud, SaaS, infrastructure, data, application, and emerging AI-enabled environments.

The role serves as the central authority for secure design and architecture across Global Cybersecurity, ensuring that security requirements are embedded upstream into technology life cycles while reducing complexity, accelerating delivery, and improving enterprise cyber resilience.

This role reports to the Deputy CISO, SVP.What you will be responsible for Drive the vision, strategy, and mission accomplishment of the entire Security Architecture organization.

Establish and scale an enterprise security architecture model that embeds secure-by-design principles into technology development, engineering, and operational processes.

Define and maintain enterprise security baselines, architecture standards, and design guardrails that enable consistent implementation of security controls across cloud, SaaS, infrastructure, application, API, data, and AI environments.

Develop and operationalize reference architectures and reusable security patterns that accelerate technology delivery while reducing cyber risk and architectural complexity.

Establish and lead a Security Architecture Center of Excellence responsible for security design guidance, threat-informed architecture practices, technology standards, and cybersecurity innovation.

Drive adoption of threat modeling as a foundational design discipline, ensuring security risks are identified and addressed before deployment and operationalization.

Lead security architecture and design reviews for strategic technology initiatives, enabling informed risk decisions and alignment with enterprise cybersecurity requirements.

Partner with technology product owners, engineering organizations, and enterprise architects to ensure security is designed into platforms, applications, services, and infrastructure rather than applied through downstream controls.

Establish target-state architecture and drive integration across cyber defense, threat intelligence, vulnerability management, analytics, engineering, and operational response capabilities.

Drive the design and evolution of integrated security architectures that improve visibility, detection, investigation, and response across the enterprise.

Lead architecture strategy for frontier technologies including cloud-native platforms, AI-enabled solutions, automation technologies, APIs, advanced analytics, and autonomous systems.

Ensure security architectures address dynamic risks associated with emerging technologies, third-party integrations, cloud adoption, and evolving threat actor capabilities.

Collaborate closely with Fusion & Security Operations, Platform Security, enterprise architecture, and technology infrastructure teams to ensure cohesive, end-to-end protection across the technology ecosystem.

Define clear accountability models, governance structures, and performance metrics that enable technology teams to effectively manage cyber risk while aligning to enterprise standards and regulatory expectations.

Desired Outcomes Secure-by-design principles are consistently embedded across technology development and engineering practices, reducing reliance on downstream security intervention.

Security baselines, architecture standards, reference architectures, and approved security patterns are broadly adopted across technology environments, resulting in more consistent and resilient security outcomes.

Threat modeling becomes a standard component of the technology lifecycle, improving identification and mitigation of design-stage risks before deployment.

A Security Architecture Center of Excellence serves as the authoritative source for architecture standards, engineering guidance, threat-informed design practices, and secure technology enablement.

Enterprise security technologies, cybersecurity data platforms, analytics capabilities, and detection systems operate within an integrated architecture that accelerates threat detection and response.

Security requirements are incorporated earlier in the technology lifecycle, reducing remediation effort, operational friction, and overall cyber risk exposure.

Cybersecurity data, telemetry, and intelligence sources are effectively connected to improve situational awareness and risk-informed decision making.

Architecture standards and secure design patterns reduce technology complexity while improving resilience, scalability, and operational efficiency.
