The Ontario Securities Commission (OSC) is the statutory body responsible for regulating Ontario’s capital markets in accordance with the mandate established in the provincial Securities Act and the Commodity Futures Act.

Design and recommend security solutions that align with business objectives and industry best practices.
Identify emerging threats, assess architectural risks, and develop mitigation strategies.
Evaluate and recommend new security technologies and tools to strengthen cybersecurity capabilities.
Lead security architecture reviews and threat modeling activities for new initiatives, projects, and technology solutions.
Embed Security-by-Design and Zero Trust principles into solution design and Architecture Review Board (ARB) processes.
Develop and maintain security architecture roadmaps aligned with OSC's strategic and cybersecurity objectives.
Assess emerging technologies, including AI, automation, and digital innovation platforms, for security and risk implications.
Provide leadership on identity security, privileged access management (PAM), conditional access, Zero Trust architecture, and secure access strategies.

Establish security metrics, KRIs, and KPIs to support informed decision-making.
Conduct security reviews and provide recommendations to improve controls and security effectiveness.
Support compliance with industry frameworks such as NIST, CIS Controls, and ISO 27001.
Support the development and maintenance of security policies, standards, reference architectures, and control frameworks aligned with NIST CSF 2.0, ISO 27001, and industry best practices.
Lead Information Security Assessments (ISAs), threat and risk assessments, and cybersecurity due diligence activities.

Strengthen Third-Party & Cloud Security

Assess suppliers and vendors for security risks and compliance.
Review security assurance reports and collaborate on contractual security requirements.
Guide secure cloud adoption across Azure and AWS environments.
Promote secure development practices and DevSecOps integration.
Assess third-party cybersecurity programs beyond SOC reports and certifications.

Support vendor security reviews, procurement initiatives, and technology risk assessments.

Provide Leadership & Advisory Expertise

Act as a trusted advisor to senior leaders, project teams, and technology stakeholders.
Contribute to cybersecurity strategy, governance, and awareness initiatives.
Support vendor evaluations, procurement activities, and strategic technology decisions.
Provide technical leadership and mentorship across security and cross-functional teams.

What You Bring

12+ years of progressive experience in Security Architecture, Cybersecurity, Enterprise Architecture, or Information Security, including experience providing strategic guidance to senior leadership.

Expertise in security architecture, threat and risk assessment, governance, and compliance.
Strong knowledge of cloud security, application security, network security, and secure systems design.
Ability to translate complex technical risks into practical business recommendations.
Exceptional communication, stakeholder management, and influencing skills.
