• Demonstrated experience with leading technical tools integration in a complex environment
• Experience in Cybersecurity Architecture, Threat Modeling, or AI/ML engineering.
• Strong understanding of AI/ML concepts, architectures, and common frameworks (e.g., TensorFlow, PyTorch, Scikit-learn).
• Applied knowledge of threat modeling and threat modeling techniques (e.g., STRIDE, DREAD, PASTA) and security risk assessment.
• The ability to extract/clarify/understand business requirements and solution designs from project teams, to identify threats and risks and to translate potential risks into security requirements which the project teams must implement
• Familiarity with AI/ML-specific threats such as adversarial examples, model extraction, and data poisoning.
• Excellent analytical, communication, and documentation skills.
• Ability to communicate complex AI security risks to technical and non-technical stakeholders is a must.
• Ability to work collaboratively in cross-functional teams.
• Experience with cloud-based AI/ML platforms (e.g., AWS SageMaker, Azure ML, Google AI Platform).

• Security certifications (e.g., CISSP, CCSP, OSCP) or AI/ML certifications are a plus.
• Experience with threat modeling tools and knowledge of MITRE frameworks (ATLAS, CAPEC, ATT&CK, D3FEND)

Responsibilities

• Analyze the design and architecture of AI solutions (chatbots, agents, agentic systems, etc.) to identify security vulnerabilities, threats, and attack vectors
• Develop and maintain threat models for AI/ML systems, considering adversarial machine learning, data poisoning, model inversion, prompt injection, privacy risks, misuse scenarios, and other AI-specific threats.
• Assess AI system components (including data pipelines, model training, inference, APIs, deployment environments, etc.) for susceptibility to attacks and compliance with security standards.
• Create detailed threat reports outlining identified risks, recommended mitigations, and business impact.
• Collaborate with business units, product owners, and engineering teams to prioritize and implement security controls and mitigations for the vulnerabilities and risks found.
• Stay current with emerging threats, vulnerabilities, and best practices in AI/ML security.
• Provide training and guidance to technical teams on secure AI/ML development and deployment practices.
• Contribute to the development of AI security architecture frameworks, policies, and standards.
