As a global leader in innovative wealth management, asset servicing, asset management and banking services, Northern Trust (Nasdaq: NTRS) is proud to guide the world’s most successful individuals, families, corporations and institutions.

Since 1889, we have aligned our efforts with our three guiding Principles That Endure: Service, Expertise, and Integrity. Together, they reflect the three cornerstones of business conduct which we strive to instill in our employees, whom we call partners, and to provide to our clients and the communities we serve worldwide.

Role Overview

Northern Trust is establishing an AI Security organization responsible for enabling the safe adoption of AI across the enterprise. We are seeking a Principal AI Security Architect to help define and operationalize the security architecture, governance patterns, and technology guardrails that support enterprise AI platforms, agentic systems, digital coworkers, and emerging technologies.

This is a highly hands-on architecture role. The successful candidate will actively create architecture artifacts, design patterns, diagrams, reference architectures, security requirements, and reusable guidance while partnering closely with engineering, enterprise architecture, identity, data, application security, infrastructure, and risk teams.

  • Develop architecture standards and guardrails for enterprise AI adoption.
  • Identify recurring design decisions and convert them into reusable reference material.
  • Contribute to enterprise-wide AI security strategy and architecture direction.

Enterprise Collaboration

  • Provide technical recommendations that balance innovation, security, operational complexity, and business value.

Required Qualifications

  • 8+ years of experience in security architecture, enterprise architecture, cloud architecture, engineering, or related disciplines.
  • Experience designing and reviewing complex enterprise technology solutions.
  • Strong understanding of: Identity and access management Authentication and authorization Cloud security Application security Network security API security Data protection Logging and monitoring Secrets management
  • Experience with Microsoft Azure or comparable cloud platforms.

  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
