Job summary

WRITER is hiring a staff-level Security engineer to build AI-focused detection and automated response for threats targeting the AI platform, training data, and model deployments. You will design detections for AI threats, automate responses, and coordinate incident handling across Cloud, AppSec, Enterprise, and AI Security teams.

The role involves threat hunting across GPU clusters and training infrastructure, building detections as code, onboarding telemetry, and maintaining 24/7 on-call

Qualifications

• 3-5+ years experience in security operations, detection engineering, or incident response with a track record of identifying and stopping sophisticated production attacks.
• Experience securing AI/ML infrastructure, high-performance computing environments, or other distributed systems at scale.
• Strong programming ability in Python and/or KQL and/or SPL to build custom detection logic, automate response workflows, and operationalize security across cloud-native and distributed computing environments.
• Experience with SIEM platforms, detection technologies, and forensic investigation techniques.
• Proven ability to build detections for novel attack techniques without established patterns and to conduct forensics in complex distributed environments.

Responsibilities

• Design and implement detection strategies for AI-specific threats, including prompt injection, model extraction, data poisoning, adversarial examples, and unauthorized access to training datasets or model weights across distributed infrastructure.
• Build automated response playbooks and orchestration workflows to contain threats without human intervention, supporting self-healing security systems.
• Remediate compromised inference endpoints through automated actions.
• Coordinate security incident response across teams when AI infrastructure or models are compromised.
• Conduct forensic investigations for training pipeline attacks and model manipulation attempts.
• Draft clear incident communications for engineering and executive leadership.
