• Recommend security capabilities and technologies to platform teams to enable secure operation of AI platforms.

• Develop security standards and best practices that become reusable patterns across the enterprise.

• Research emerging AI security threats and translate findings into actionable guidance for solution architects and platform teams.

• Create architectural blueprints and decision frameworks that guide teams toward secure AI implementations.

• Map regulatory requirements (OSFI E-23, SR 11-7, EU AI Act) to architectural patterns and provide compliance guidance to implementation teams.

• Assess and recommend security technologies and tools that platform teams should adopt to build secure AI platforms.

• Collaborate with enterprise architecture teams to ensure AI security patterns integrate with broader enterprise standards.

• Present architectural guidance and recommendations to senior stakeholders and technical teams.

What do you need to succeed?

Must have:

• 5+ years of enterprise security architecture experience.

• Deep knowledge of security frameworks (NIST, ISO 27001, Zero Trust) and cloud-native security technologies.

• Understanding of AI/ML systems architecture including LLMs, vector databases, and agentic AI patterns.

• Knowledge of financial services regulations (OSFI guidelines, SR 11-7, Model Risk Management) and AI-specific regulations (EU AI Act, NIST AI RMF)

• Strong communication skills with ability to translate complex technical concepts into business language for executive audiences.

• Experience with threat modeling, risk assessment frameworks, and security analysis for emerging technologies.

• Understanding of authentication protocols (OAuth 2.1, OIDC, SAML, mTLS) and enterprise integration patterns.

Nice to have:

• Security certifications (CISSP, SABSA) or cloud security certifications (AWS Security Specialty, Azure Security Engineer)

• Experience with AI security tools and adversarial testing methodologies.

• Previous experience implementing AI systems in regulated financial environments and algorithmic trading security requirements.

• Active participation in AI security research communities (OWASP AI Security, MITRE ATLAS) or published thought leadership.

• Multi-jurisdictional regulatory experience and cross-border data governance knowledge for AI systems.

• Experience with FINOS frameworks, SPIFFE/SPIRE for workload identity, or service mesh architectures for AI workloads.

• Previous experience in large financial services organizations.

We thrive on the challenge to be our best, progressive thinking to keep growing, and working together to deliver trusted advice to help our clients thrive and communities prosper.
