Job Description

The Principal AI Security Engineer acts as an enterprise subject-matter expert focused on securing AI platforms and the surrounding ecosystem, including agents, integrations, APIs, data sources, and supporting infrastructure. This role identifies AI-specific threats and converts governance and risk expectations into scalable technical safeguards and reusable security patterns across the organization.

Role Focus

  • Serve as the enterprise security expert for AI platforms, AI agents, integrations, APIs, and emerging AI use cases.
  • Assess AI-related risks, including prompt injection, data exposure, insecure tool invocation, excessive agency, and adversarial inputs.

Key Responsibilities

  • Design, implement, and validate security controls for AI platforms, including data protection, access controls, monitoring, guardrails, and approved data-use patterns.
  • Perform security architecture reviews, threat modeling, control assessments, and risk-based evaluations for AI solutions and third-party services.
  • Translate policies, governance requirements, and control frameworks into practical technical requirements, implementation plans, and operational processes.
  • Develop monitoring, logging, detection, and investigation capabilities for AI activity and integrate relevant telemetry into security operations.
  • Partner with Security Operations and incident response teams to strengthen AI-related detection, investigation, and response processes.
  • Collaborate across technical and governance teams to incorporate security requirements into AI platforms, services, and workflows.
  • Create reusable security patterns, implementation guidance, metrics, and evidence to support engineering, governance, risk, and audit activities.
  • Monitor changes in AI technologies, threats, and industry guidance, evolving the organization’s security approach accordingly.

Required Qualifications

  • 10+ years of experience in security engineering, cloud security, data security, application security, detection engineering, or a related technical security discipline.
  • Experience implementing, operating, or validating security controls such as data protection, DLP, SIEM, cloud security, API security, endpoint security, or application security.
  • Experience conducting security assessments, architecture reviews, threat modeling, or other risk-based security evaluations.
  • Experience translating security risks and governance requirements into practical technical safeguards and implementation plans.
  • Strong understanding of data protection, including sensitive data discovery, classification, encryption, privacy, and secure data handling.
  • Strong analytical, communication, and collaboration skills to align technical and nontechnical stakeholders on practical solutions.
  • Bachelor’s degree.

Preferred Qualifications

  • Experience securing AI platforms, AI agents, machine learning systems, or other emerging technologies.
  • Knowledge of AI-specific threats, including prompt injection, model misuse, sensitive data exposure, adversarial inputs, and insecure tool invocation.
  • Familiarity with AI architectures and services such as APIs, Model Context Protocol services, retrieval-augmented generation, guardrails, and human-in-the-loop controls.
  • Experience automating security processes using scripting, APIs, infrastructure as code, or similar approaches.
  • Familiarity with NIST AI RMF, NIST Cybersecurity Framework, ISO/IEC 27001, ISO/IEC 42001, or OWASP guidance for AI applications.
  • Experience developing reusable security patterns that support emerging technology adoption while managing risk.
