Head of AI Security Architecture

Role Overview

• Define and steward State Street’s enterprise AI security architecture, including secure-by-default patterns for AI platforms, GenAI tooling, AI agents, and data pipelines.
• Establish architecture standards, guardrails, and reference designs for AI systems across cloud and on-prem environments.
• Embed security, privacy, and compliance requirements directly into AI and software engineering lifecycle processes.
• Partner with Enterprise Architecture and Engineering to ensure AI security scales across product teams with minimal friction.
• Establish and mature AI threat modeling practices, aligned to real-world attacker behavior and regulatory scrutiny.
• Lead identification and mitigation of AI-specific risks including model abuse, data poisoning, OSS corruption, prompt injection, model inversion, and emerging adversarial AI threats.
• Drive defensible architecture decisions supported by measurable risk reduction and operational outcomes.
• Integrate AI security into DevSecOps pipelines, automating preventative, detective, and responsive controls.
• Enable secure AI adoption through paved-road platforms, automation, and architectural simplification.
• Partner with engineering teams to accelerate AI reviews and approvals through tooling and policy-as-code approaches.
• Lead security architecture for emerging AI capabilities, including AI agents, automation frameworks, and developer assist tooling.
• Collaborate with crypto and platform teams on post-quantum readiness considerations as they relate to AI systems and long-lived data.
• Continuously evaluate new AI security technologies and patterns to strengthen the firm’s defensive posture.
• Drive data-driven security architecture decisions, using metrics to identify risk concentration, architectural friction, and opportunities to reduce security burden.
• Ensure architecture standards align with and support regulatory expectations (FFIEC, NIST, ISO, NYDFS, GDPR, etc.).
• Contribute to incident response preparedness for AI-related events, including misuse and systemic failures.
• Serve as a trusted technical advisor to the CISO, CIO, architecture leadership, and senior engineering leaders.
• Deliver concise executive briefings on AI security posture, emerging risks, and architectural tradeoffs.
• Support regulatory, audit, and client discussions with credible, defensible technical narratives.
• Build and lead a high-performing AI Security Architecture team.
• Act as a multiplier for security engineering, product security, and platform teams through coaching and architectural leadership.
• Foster a culture focused on customer trust, innovation, and continuous improvement.
