Our client requires a Senior Cyber Security Architect to support the Director, Cyber Security Defence & Resilience, with both operational and strategic initiatives. The role will focus on the two primary areas of: 

• Cyber Security Incident Response (CSIR): Enhancing program maturity, strengthening governance, and supporting the coordination of day-to-day cyber security incidents.  

• Zero Trust Implementation: Supporting the hands-on implementation and operationalization of Zero Trust principles and technologies across the enterprise. 

This role is not deeply technical (e.g., digital forensics), but requires a strong background and hands-on in CSIRT/Security Operations and Zero Trust implementation to ensure delivery of real, measurable outcomes and an operational Zero Trust model. 

Work is hybrid. 

Mandatory Requirements

• Minimum 7–10 years of experience in cyber security, with strong exposure to Incident Response / Security Operations (CSIRT/SOC) 

• Proven experience coordinating and managing cyber incidents, including communication with internal and external stakeholders 

• Strong ability to produce clear, concise reports, executive briefings, and incident communications 

• Experience developing incident response procedures, policies, standards, and playbooks 

• Proven hands-on experience implementing Zero Trust technologies, particularly in identity and access management (IAM) 

• Demonstrated ability to assess security environments and identify gaps, especially across identity and network security domains 

• Strong experience with identity-focused controls (e.g., MFA, Conditional Access, identity governance, privileged access) 

• Practical experience translating Zero Trust concepts into operational controls and measurable outcomes 

• Experience working with Microsoft security ecosystem (e.g., Defender, Sentinel, Entra ID) and AWS security ecosystem (e.g., Guard Duty, Security Hub, 

• Solid understanding of network security concepts aligned to Zero Trust (e.g., segmentation, secure access models) 

• Excellent written and verbal communication skills, including executive-level engagement 

• Working awareness of the modern AI-driven threat landscape (e.g., AI-accelerated exploitation, automated / machine-speed attacks) and its implications for incident response and Zero Trust priorities 

Desirable Requirements

• Experience in healthcare or public sector environments, particularly Ontario health sector 

• Familiarity with regulatory and security frameworks (e.g., PHIPA, NIST CSF, ISO 27001) 

• Experience supporting cross-organizational incident response coordination 

• Experience implementing Conditional Access, PAM/PIM (Privileged Access Management/Privileged Identity Management), or identity governance solutions 

• Exposure to Zero Trust maturity models or assessments 

• Knowledge of cloud security environments 

• Experience with network micro-segmentation or Zero Trust Network Access (ZTNA) 

• Experience with SOAR (Security Orchestration Automation and Response) platforms or automation of incident workflows 

• Relevant certifications (e.g., CISSP, CISM, GIAC, Azure Security Engineer) 

• Familiarity with defending against AI-driven / adversarial-AI threats and machine-speed attack techniques 

• Exposure to program-delivery models where security work is organized into coordinated workstreams (e.g., attack-surface reduction, CTEM, AI-enabled detection)
