• Evaluate and secure AI/ML systems, including model governance, data pipelines, and deployment patterns.
• Advise on AI risk management: prompt injection, model poisoning, data leakage, privacy risks, and adversarial attacks.

• Knowledge of modern attack techniques including AI-assisted attacks, adversarial ML, and supply-chain risks.
• Familiarity with cloud security frameworks (AWS, Azure, GCP) and industry standards (NIST, ISO 27001, OWASP, MITRE ATLAS).
• Excellent communication and client-facing skills, able to translate technical concepts for non-technical stakeholders.

Desirable:

• CISSP, CCSP, OSCP, CEH, GIAC, or cloud security certifications.
• Experience with AI model evaluation, fine-tuning, RAG pipelines, or vector databases.
• Knowledge of AI ethics, governance, and regulatory frameworks (EU AI Act, NIST AI RMF, ISO/IEC 42001).
• Familiarity with DevSecOps, automation, IaC, and security control integrations.

Security Clearance: Required. Candidates must be eligible for SC/DV clearance.
