Responsibilities
- Set the technical direction for AI threat defense across Thomson Reuters, ensuring AI-specific risks are addressed through the organization's core cyber defense strategy, architecture, engineering practices, and operating model
- Define how the organization monitors, detects, investigates, and responds to attacks involving AI-enabled products, LLM applications, agentic workflows, models, AI infrastructure, and associated integrations
- Develop defensive approaches for AI-specific threats, including prompt injection, jailbreaks and guardrail bypass, sensitive-information and system-prompt disclosure, unsafe downstream execution, excessive agent autonomy, unauthorized tool use, MCP exploitation, model and data poisoning, AI supply-chain compromise, model denial-of-service and denial-of-wallet attacks, model, prompt, and intellectual-property theft, and deepfake-enabled social engineering
- Partner with Product Engineering, Security Engineering & Architecture, and AppSec to establish secure, observable, and defensible patterns for AI-enabled applications, services, infrastructure, agents, and tool-use workflows
- Ensure AI security requirements, meaningful telemetry, and response readiness are designed into the software development lifecycle and production operating environment
- Strengthen existing security telemetry, detection engineering, monitoring, incident investigation, and response practices to identify and contain AI-related threats effectively
- Architect the responsible use of AI within the existing 24/7 SOC and CIRT operating model to improve triage, investigation, decision-making, response execution, and analyst effectiveness
- Develop detection content, security analytics, investigation methods, playbooks, and response workflows that enable SOC and CIRT teams to investigate and respond to AI-related security events
- Maintain appropriate human oversight, evidence quality, auditability, safeguards, and rollback mechanisms as AI capabilities are adopted within Cyber Defense operations
- Track emerging offensive AI capabilities, adversary tooling, threat-actor adoption, AI vulnerability research, and changes in the broader threat landscape, translating findings into practical defensive improvements
- Provide technical leadership and mentorship across Cyber Defense, raising organizational capability in AI security, detection engineering, threat analysis, and incident response
- Influence technical decisions through architecture reviews, technical standards, direct engineering collaboration, design guidance, and clear communication with technical and executive stakeholders
- Represent Thomson Reuters in relevant customer discussions, industry groups, regulatory engagements, and AI security communities

- A proven ability to establish technical strategy and deliver security capabilities that are adopted across multiple teams, systems, and operating functions
- Practical experience securing or governing AI-enabled systems, including LLM applications, AI infrastructure, models, agentic workflows, AI integrations, MCP, or comparable tool-use patterns
- Strong understanding of AI security risks, including prompt injection, data exposure, unsafe model output and downstream execution, agent and tool abuse, model and data poisoning, AI supply-chain risk, and AI-enabled social engineering
- Proven experience architecting or delivering AI-assisted detection and response capabilities within a mature 24/7 SOC, CIRT, or comparable cyber defense environment
- Experience strengthening an established security organization and driving adoption of security capabilities across SOC Operations, CIRT, Threat Detection Engineering, Vulnerability Management, and Attack Surface Reduction
- Ability to translate AI security risks into clear architectural patterns, engineering requirements, detection logic, and actionable incident-response practices
- Experience partnering with Product Engineering, Security Engineering & Architecture, and AppSec teams to embed security into development and production processes
- Exceptional communication and influencing skills, with the ability to work effectively across executive leadership, engineers, architects, analysts, incident responders, customers, regulators, and other stakeholders
- Demonstrated ability to mentor technical professionals and raise the technical capability of a broader security organization
- Experience operating within a regulated, multi-segment enterprise and partnering across legal, compliance, procurement, governance, engineering, and security organizations
- Experience in financial services, legal technology, professional information services, or another highly regulated industry is preferred
- Experience embedding significant technical capabilities into an established security operations organization is preferred
- Hands-on experience building or operating agentic AI systems across multiple LLMs, including open-weight, hosted, and frontier models, is preferred
- Experience applying AI within SAST, AppSec, vulnerability management, detection engineering, or security operations workflows is preferred
- Working knowledge of safely operating open-weight or less-restricted models for authorized internal security research is a plus
- Familiarity with frontier AI vulnerability research programs or comparable agentic vulnerability-discovery initiatives is a plus
- Active participation in AI security research, open-source communities, industry groups, conference speaking, or published research is a plus
- Relevant certifications in cybersecurity, cloud security, AI/ML security, or detection engineering are beneficial but not required
