About the role

Join us in building innovative AI/ML services that protect our cloud from security threats. As an Applied Scientist, you'll analyze data using GenAI and other AI/ML techniques to build and deploy services that detect and automate the mitigation of cybersecurity threats across Amazon's infrastructure. You'll collaborate with software development engineers, security engineers, and fellow scientists to develop innovative security solutions at massive scale, protecting the AWS cloud for all customers.

This role offers the opportunity to drive technical innovation within threat detection and mitigation, utilizing the full power and breadth of AWS technologies such as Amazon SageMaker, Bedrock, and EMR.
