Senior Security Engineer, Operational Research and Development

We are building systems that investigate and remediate security incidents at machine speed, reducing human intervention from triage to eradication to the strict minimum. Join us to define what autonomous incident response looks like at the scale of the world's largest cloud provider.Amazon Security's Operational Research and Development team combines deep security expertise with software engineering to transform how AWS responds to security events. We don't just build tools for responders; we build the intelligence that replaces manual investigation entirely: automated log dives, DFIR pipelines, fix identification, and autonomous mitigation.Key job responsibilitiesAs a Senior Security Engineer, you will: - Own the response playbooks and investigation methodology that power our automation platforms - Design and implement autonomous incident response workflows: from initial triage through root cause analysis to remediation - Build automated DFIR capabilities including log correlation, forensic evidence collection, and threat eradication at cloud scale - Drive the security domain decisions (how to investigate, when to act, what to fix) while partnering with SDEs on platform scalability- Participate in an on-call rotation focused on maintaining automation health, and seucrity escalations- Mentor engineers across the team on security domain expertise and incident response best practicesAbout the teamThe Operational Research and Development team sits within Amazon Security. We are a mixed team of Security Engineers and Software Development Engineers who share a single mission: make security incident response so fast and accurate that human involvement becomes a choice, not a necessity.Our engineers own what they build. Each person carries meaningful end-to-end ownership of production systems, from design through deployment and operational excellence.

We maintain a flexible, distributed working culture and core collaboration hours that respect personal time.We are intentional about building an inclusive environment where diverse backgrounds and perspectives drive better security outcomes.
