Description
AWS Security Incident Response is looking for a Senior Security Engineer who builds the automation mechanisms that scale security response. You will investigate complex security incidents hands-on, build the frameworks that turn investigation expertise into scalable detection and auto-remediation, and architect the AI feedback loops that make the service smarter with every investigation.
The AWS Security Incident Response team provides 24/7 security response through a follow-the-sun operating model. The service combines automated triage workflows, AI-powered investigation agents, and human security analysts to respond to threats across customer AWS environments at massive scale. Our AI systems autonomously resolve over 90% of routine investigations within minutes. The next challenge is building the mechanisms that accelerate this further — enabling every engineer on the team to contribute to detection and automation quality from their investigation work.
