What you will do

• Design detection strategies for prompt injection, model extraction, data poisoning, adversarial examples, and unauthorized access to training datasets or model weights.
• Build automated response playbooks, orchestration workflows, and self-healing security systems that contain threats and remediate compromised inference endpoints.
• Coordinate incident response across Cloud, AppSec, Enterprise, and AI Security teams; investigate training-pipeline attacks and model manipulation.
• Proactively hunt threats across GPU clusters and distributed training infrastructure, analyze model outputs, reproduce AI-specific vulnerabilities, and identify visibility gaps.
• Develop detection-as-code frameworks, onboard telemetry, and create dashboards for model security metrics, GPU utilization, and sensitive research-data access.
• Maintain a 24/7 on-call rotation for critical AI security incidents and continuously improve detection coverage and automation.
