• Provide thought leadership on security tool portfolio to align with the security architecture principles, standards, and technology roadmaps; partner with product, engineering and IT to embed security architecture from ideation through deployment.
• Oversee implementation of security architecture solutions and program investments: for example, zero trust, SSDLC, cloud security posture management, identity & access modernization, application security architecture, automation of controls, and resilient infrastructure design.

Delivery Management

• Lead the delivery of technical projects within the security organization: plan, prioritise and oversee large-scale security programs (architecture transformations, cloud migration security, global compliance initiatives, identity and access modernization, security tooling & automation) which has clear line to risk reduction
• Establish frameworks for program governance, metrics, dashboards, risk-management, resource allocation and cross-team coordination.
• Ensure delivery excellence: on time, within scope, with measurable impact (e.g., risk reduction, remediation velocity, resilience improvements).

Must-have

• 10+ years of experience in cybersecurity, enterprise IT security architecture or security engineering leadership roles.
• Proven experience (hands-on) with various security tools portfolio, including defining  enterprise security architecture and driving architecture change at scale.
• 5+ years of managing large, complex technical programs (multiple streams, cross-functional stakeholders, global scale).
• Demonstrated ability to lead and manage multiple (direct / matrix) security teams/functions (e.g., systems architecture, identity & access, cloud security, compliance tooling) through senior leads.
• Strong technical depth in cloud environments (AWS, GCP, Azure), enterprise IT controls, SaaS ecosystems, secure SDLC/DevSecOps practices.
• Excellent communication skills with senior leaders: able to convert technical complexity into business context, influence decision-making, and drive change.
• Track record of delivering measurable outcomes (risk reduction, improved security posture, automation, cost-efficiencies) in a fast-paced, high‐growth environment.
