About the role

What will you do at Amazon?

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
