OverviewSecurity engineer, detection and response at WRITER. WRITER is seeking a Detection and Response Engineer to defend our AI/AGI platforms, training data, and deployed models against sophisticated and evolving threats. This role blends hands-on security engineering with strategic threat detection, ensuring our defenses evolve faster than adversaries targeting our infrastructure. You’ll design advanced detections, automate rapid responses, and lead investigations into incidents affecting our AI stack—covering everything from GPU clusters to model inference endpoints. You’ll be the operational heartbeat of our AI security posture, partnering across security, infrastructure, and research teams to detect attacks, orchestrate containment, and safeguard our most valuable intellectual property. If you thrive on staying ahead of attackers and can turn cutting-edge AI threat intelligence into production-grade detection systems, we’d love to hear from you. Role Boundaries & Collaboration Your responsibilitiesEngineer advanced threat detection — Design and implement detections for AI/ML-specific threats including prompt injection, model extraction, data poisoning, and adversarial inputs.Automate security responses — Build playbooks and orchestration workflows that contain AI-targeted attacks in minutes, not hours.Lead AI incident response — Coordinate cross-team investigations into compromises of models, training data, and inference endpoints.Hunt for AI-specific threats — Proactively search for active attacks across GPU clusters, training pipelines, and model deployments.Enhance visibility & telemetry — Onboard, optimize, and analyze logging from AI infrastructure to detect anomalies and misuse.Collaborate across domains — Partner with AI Security on threat intelligence, Cloud/Infrastructure on runtime monitoring, and Software Security Engineering on customer-impacting incidents.
