Principal, Security Engineering and Operations

The Role

The Principal, Security Engineer is a senior individual contributor and technical lead responsible for shaping, engineering and operationalizing enterprise security platforms across Northern Trust.

This role goes beyond hands-on administration: it sets technical direction, defines durable engineering patterns, mentors engineers, influences cross-functional partners and ensures security platforms operate with the reliability, evidence quality and control discipline expected in a regulated financial institution.

The role suits an engineer who can move comfortably between executive-level risk discussions, architecture decisions and deep technical troubleshooting.

What You'll Do

Technical Lead Across Security Platform Domains

• Serve as the technical authority for security platform engineering decisions and operational governance.
• Design, engineer and operate security tools spanning zero-trust, SASE/SSE, network, vulnerability & exposure management, AI guardrails, and SaaS.
• Define engineering patterns, implementation standards and operational runbooks that enable consistent adoption across business units and technology teams.
• Develop maturity models and metrics to measure assurance and compliance.
• Coordinate cross-functional security initiatives across engineering, infrastructure, and application teams.

Key Deliverables

• Design, Engineer, Coordinate and Operate:
• Intrusion prevention(IPS) across next-gen firewalls
• Vulnerability scanning platforms and unified vulnerability management(UVM) layer
• Enterprise SASE / SSE security platforms
• Secure web gateway, CASB, and cloud access protection
• SaaS application protection and monitoring
• Secure remote access and internet traffic inspection
• Browser isolation and modern web threat prevention
• AI gateway controls that govern how users and applications consume LLMs and AI services
• ServiceNow integrations (Vulnerability Response, ITSM, CMDB)
• Own technical outcomes for platform health, upgrades, capacity, resilience, lifecycle management and vendor escalations across the stack.
• Define and publish metrics on coverage, control effectiveness, SLA adherence, tool health, control performance and measurable risk reduction.
• Support audits and regulatory exams (PCI-DSS, SOX, GLBA, OCC/FFIEC) by ensuring controls are designed for evidence quality, traceability and repeatable operation.
• Author runbooks and executive-ready documentation that can be used by engineering, operations, risk and audit stakeholders.
• Lead evaluation of new capabilities, proofs of concept and tool rationalization efforts, with clear recommendations based on risk reduction, operational fit, cost and control outcomes.

What You'll Bring

• Typically 15+ years of experience in information technology, cybersecurity, cloud, infrastructure, network security or platform engineering, with demonstrated ownership of enterprise-scale security platforms.
• Proven ability to operate as a senior technical leader: setting direction, influencing without direct authority, mentoring engineers and making sound tradeoffs across security, reliability, usability and compliance.
• Deep hands-on experience with at least one SSE/SASE platform, including ZTNA, secure web gateway policy, segmentation, connector architecture and operating model design.
• Working knowledge of IPS/next-gen firewall platforms and signature tuning.
• Strong networking fundamentals: TCP/IP, routing, DNS, TLS/PKI, proxies and tunneling (IPsec/GRE), and segmentation.
• Experience with vulnerability management tooling.
• Familiarity with identity integration: SAML/OIDC, Entra ID, conditional access.
• Scripting and API skills (Python, PowerShell, REST/JSON).
• Experience integrating security tools with ServiceNow, SIEM platforms and enterprise reporting workflows.
• Excellent communication skills, including the ability to brief senior stakeholders, document technical decisions, support audit inquiries and drive alignment across teams you do not directly manage.
• Experience working in a regulated environment with control evidence, operational resilience, risk acceptance, issue management and audit/regulatory response expectations.

Nice to Have

• Exposure to AI/LLM security controls:
• AI gateways
• Prompt-injection defenses
• OWASP Top 10 for LLM Applications
• MITRE ATLAS
• ServiceNow Vulnerability Response or USEM implementation experience.
• Low-code automation or Terraform/IaC.
• Prior experience in financial services, banking, asset servicing, wealth management or another highly regulated industry.
