As part of the AWS Applied AI Solutions organization, we're advancing the frontier of trust and safety systems for cloud-based communication services. Our vision is to be the trusted foundation for transforming every business with Amazon AI teammates. Our mission is to deliver turnkey, enterprise-grade foundational AI capabilities that create delightful AI powered solutions. We're building sophisticated AI systems that protect infrastructure from evolving threats while enabling legitimate high-volume users to operate without friction, with messaging services at scale as a key application area.
Key job responsibilities
- Develop advanced machine learning approaches and agentic systems that autonomously adapt to evolving threat patterns across cloud communication services
- Create behavioral detection models that quickly identify malicious patterns after onboarding rather than creating friction during signup
- Design intelligent resource allocation algorithms that optimize service delivery based on real-time feedback
- Develop frameworks operating at scale across diverse usage patterns, analyzing hundreds of thousands of daily active customers
- Research novel approaches combining AI agents with trust and safety systems to solve complex security problems
- Collaborate with engineering teams to integrate science components into production systems
- Conduct rigorous experimentation and establish evaluation frameworks to measure solution performance
A day in the life As an Applied Scientist, you'll develop fraud detection algorithms and AI-powered security systems while maintaining a clear path to customer impact. You'll investigate novel approaches to behavioral analysis, develop methods for real-time reputation assessment, and validate ideas through rigorous experimentation. You'll collaborate with other scientists and engineers to transform research insights into scalable solutions, work directly with enterprise customers to understand requirements, and help shape the future of cloud security technology.
