• Build defenses against direct and indirect prompt injection and other adversarial inputs to LLM applications
• Establish data security controls for sensitive data flowing through inference, retrieval, and fine‑tuning

Security Operations

Lead incident response for cloud and AI infrastructure security incidents

• Develop and implement security monitoring and detection strategies
• Conduct threat modeling and risk assessments for cloud-native and AI systems
• Perform regular security assessments of cloud infrastructure and container deployments
• Create and maintain security documentation, including policies, procedures, and run‑books

Leadership & Collaboration

Collaborate with development, data science, and operations teams to integrate security

• Communicate security requirements and recommendations to technical and non‑technical stakeholders
• Stay current with emerging threats and security trends in cloud-native and AI security
• Participate in technology selections for security tooling and platforms

• Working knowledge of AI/ML and LLM security, including familiarity with frameworks like TensorFlow and PyTorch and their security implications
• Proficiency in scripting and programming languages (Python, Go, Bash)
• Experience with security automation and orchestration

Preferred Experience

• Deep experience securing Large Language Models (LLMs) and generative AI systems
• Familiarity with AI/LLM security frameworks (e.g., OWASP LLM Top 10) and AI governance or compliance requirements
• Experience with secure multi-tenant AI infrastructure
• Experience with privacy-enhancing technologies for AI/ML (differential privacy, federated learning)
