SECURITY ARCHITECT Toronto

We are looking for a Security Architect to join our consulting team on a permanent basis. This is a hybrid position. As a Chrome Technologies consultant, the successful candidate will work with our clients to deliver the projects they have entrusted to us.

Key Responsibilities

Architecture Review & Advisory

• Lead security reviews of solution and domain architectures, ADRs, and AI-enabled platforms.
• Assess GenAI and agentic solution designs for model security, data protection, prompt integrity, provenance, and safe orchestration of agents.
• Evaluate proposals for alignment with enterprise standards, regulatory expectations, and risk tolerance.
• Produce actionable review comments with traceable recommendations, covering both traditional and AI-driven architectures.

Authoring & Governance

• Author and maintain ADRs, patterns, and reference architectures-including those covering GenAI system integration, LLM usage, and multi-agent frameworks.
• Ensure architectural documentation expresses the problem space, options, controls, and trade-offs clearly and defensibly.
• Promote structured architectural reasoning supported by both human and GenAI-assisted analysis workflows.

GenAI & Agentic Security

• Define and assess controls for GenAI systems, including:
  • Model access, data boundary, and prompt injection defenses.
  • Guardrails for AI agents performing autonomous actions or multi-step reasoning.
  • Secure orchestration, isolation, and human oversight mechanisms.
• Evaluate the security of agent frameworks, LLM pipelines, and model-hosting platforms (e.g., Vertex AI, Azure OpenAI).
• Contribute to enterprise policy for responsible AI use and GenAI-assisted development.

Technical Leadership

• Provide domain expertise in application, cloud, and data security-augmented by AI security design considerations.
• Support teams in safely embedding GenAI copilots, RAG systems, and autonomous agents within business processes.
• Lead threat modeling for composite systems where GenAI interacts with APIs, data stores, and user environments.

Continuous Improvement & Automation

• Use and refine GenAI tools for document review, security design assistance, and ADR quality assurance.
• Develop reusable prompts, review heuristics, and decision frameworks that enhance SARB throughput and consistency.
• Mentor peers in human-AI collaborative authoring, emphasizing accountability and verification of AI output.
• Build agentic AI security harnesses, prototypes, and POCs for new cyber capabilities.
• Research AI Security, Agentic AI, Application Security, quantum/PQC, blockchain, and other emerging technologies.
• Develop and integrate agents, LLMs, APIs, security tools, automation, and test environments.
• Evaluate new cybersecurity products and startups through hands‑on testing, benchmarking, and technical due diligence.
• Validate vendor claims and assess security, scalability, integration complexity, and enterprise applicability.
• Help transition successful research prototypes toward operational use.
• Present technical findings and recommendations to engineering, security leadership, and investment stakeholders

Core Competencies

• Enterprise security architecture (SABSA, TOGAF, NIST CSF).
• GenAI systems architecture, LLM lifecycle, and model governance.
• AI security patterns (threat modeling for LLMs, data leakage prevention, agent control).
• Strong authorship and analytical writing-clear articulation of decisions and consequences.
• Familiarity with tools for architectural diagramming, review automation, and GenAI-assisted design (e.g., LangChain, OpenAI GPT, Guardrails AI).
• Broad experience across cloud, data, application, and API securitydomains.
