Full Job Description
Job Summary:
  • Pinnacle Financial Partners is seeking a pioneering AI Security Architect to lead the secure adoption of AI across the enterprise and embed advanced AI capabilities within our security program. This is a senior, hands-on engineering and architecture role with direct leadership visibility - reporting to the Chief Security Officer and carrying the mandate to build out a dedicated AI Security team.

Job Duties and Responsibilities:

  • Design, build, and maintain the secure architecture for Pinnacle's AI environment, including Microsoft Copilot, Anthropic Claude, and future AI services integrated across the enterprise.
  • Engineer security controls, guardrails, and monitoring pipelines for AI platforms, including prompt injection defenses, data leakage prevention, model access governance, and output validation.
  • Develop and enforce AI security standards, reference architectures, and engineering playbooks aligned to NIST AI RMF, MITRE ATLAS, and emerging financial sector guidance.
  • Collaborate with the AI team (led by Kevin Johnson) on new AI deployments to ensure security-by-design is embedded from inception through production.
  • Own the technical integration of AI security tooling within Pinnacle's Azure-centric stack, including M365, Entra ID, Defender, and Purview.

AI-Powered Security Operations
  • Lead the engineering and deployment of AI capabilities within the Security Operations Center to accelerate threat detection, triage, and incident response.
  • Build and optimize AI-assisted workflows within SIEM (Microsoft Sentinel), SOAR, and vulnerability management platforms to reduce analyst toil and improve mean time to respond.
  • Develop and operationalize AI-driven threat intelligence and anomaly detection models tailored to Pinnacle's environment and financial sector threat landscape.
  • Identify and drive automation opportunities across the security program using AI - from phishing analysis and alert enrichment to policy compliance checks and reporting.

AI Risk & Compliance
  • Assess AI-specific risks including model supply chain threats, adversarial inputs, shadow AI usage, and third-party AI vendor exposure across Pinnacle's ecosystem.
  • Partner with Legal, Compliance, and Risk teams to align AI security practices with applicable regulations (FFIEC, OCC, GLBA, SOX) and Pinnacle's internal control frameworks.
  • Establish and maintain an AI asset inventory and risk register; perform periodic AI security reviews and red-team exercises.
  • Evaluate and advise on the security posture of AI vendors and SaaS platforms before and after procurement, providing risk-rated recommendations to the CSO.

TEAM LEADERSHIP AND EVANGILISM
  • Recruit, mentor, and grow an AI Security team as the practice matures - establishing role definitions, career paths, and onboarding frameworks.
  • Serve as the internal subject matter expert and evangelist for AI security, providing education and guidance to engineering, IT, and business teams.
  • Maintain active engagement with the broader security community, staying ahead of AI threat trends, attack research, and defensive tooling advancements.
  • Collaborate closely with Pinnacle's AI team (AI Governance owner) to ensure alignment on AI strategy, risk tolerance, and control responsibilities.
