Job summary

Thomson Reuters Corp. is seeking a Distinguished Engineer to lead AI threat defense, shaping security strategy for AI-enabled products and enterprise operations.

You will define monitoring, detection, and response for AI threats, and mentor teams across SOC, CIRT, and product security. The role requires deep hands-on cyber defense experience, architecture acumen, and the ability to communicate complex AI security risks to engineers, executives, and regulators.

Qualifications

• 12+ years of progressive experience in cybersecurity, security engineering, security architecture, threat detection, incident response, or a related technical field.
• Experience operating as a Principal, Staff, Distinguished Engineer, or equivalent senior technical leader within a large, complex organization.
• Strong hands-on experience in Cyber Defense, including detection engineering, security operations, threat hunting, security analytics, incident response, security architecture, or closely related disciplines.

Responsibilities

• Set the technical direction for AI threat defense across Thomson Reuters.
• 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.
