Are you passionate about using science to make the digital world more secure? The AppStar Data Analytics & Engineering (DNA) team within Amazon's Application Security organization is looking for an Applied Scientist III to invent and build ML-driven systems that fundamentally change how Amazon identifies, prioritizes, and mitigates application security risk at scale.
Our team sits at the intersection of data science, machine learning, and security operations. We build the intelligence layer that powers Amazon's application security programs: risk-scoring models that rank tens of thousands of applications, graph-based systems that map security context across architectures, and analytics platforms that drive data-informed decisions for security leadership. This is science with direct, measurable impact on Amazon's security posture.
As an Applied Scientist III, you will lead the invention and delivery of novel ML solutions for complex, ambiguous problems in the security domain. You will work with large-scale datasets spanning application metadata, code signals, vulnerability findings, and organizational context to develop models that help Amazon focus security resources where they matter most.
Key job responsibilities
- Lead the design, development, and deployment of ML models and scientific solutions for application security prioritization, complexity scoring, and risk assessment
- Frame ambiguous security problems into well-defined scientific challenges, proposing novel approaches when existing methodologies are insufficient
- Architect and implement production-grade ML pipelines (feature extraction, model training, scoring, deployment) on AWS services (S3, Glue, SageMaker, Neptune)
- Develop and extend graph-based models that capture security-relevant relationships between applications, services, teams, and vulnerabilities
- Drive the team's scientific agenda by proposing new research initiatives, conducting experiments, and iterating on models using rigorous evaluation methodologies
- Partner with security engineers, data engineers, and TPMs to translate model outputs into actionable intelligence for security review programs
- Establish and raise the bar for scientific rigor: peer review code and designs, set best practices for experimentation, and document findings for reproducibility
- Publish results internally and externally at peer-reviewed venues when appropriate
About the team
