Applied Scientist Ii, Perimeter Protection Applied Science

Amazon Amazon · Big Tech · Seattle, WA · Data Science

This role focuses on designing, developing, and deploying AI/ML models for cybersecurity threats within AWS. It involves leveraging LLMs, generative AI, and agentic AI systems to build production-grade security solutions at scale, processing trillions of requests weekly. The role spans the entire ML lifecycle from data exploration to deployment and requires collaboration with engineers for integration into low-latency systems.

What you'd actually do

  1. Design, develop, and evaluate ML models and algorithms for threat detection, anomaly detection, and mitigation of evolving cyber threats including DDoS attacks, bot activity, and web application exploits.
  2. Explore and apply large language models, generative AI, and agentic AI approaches to security challenges such as automated threat analysis, intelligent mitigation, and adaptive defense systems.
  3. Implement end-to-end ML solutions — from data exploration and feature engineering through model training, evaluation, and deployment into production systems.
  4. Analyze large-scale datasets to uncover patterns, identify emerging threat vectors, and translate findings into effective ML-based security solutions.
  5. Build and maintain data pipelines and model training workflows that support rapid experimentation and reliable production performance.
