Applied Scientist, Leo Security

Amazon Inc.; Arlington (VA); Presencial; USD 143.000 - 193.000; Jornada completa

Descripción de la vacante

Amazon is seeking a Security Data Scientist for the Leo Space Security team. You will build behavioral and statistical models to baseline normal activity across heterogeneous security telemetry, including OT/SCADA data sources, and design privacy-preserving representations of sensitive data.

You will define the methodology for difficult problems, develop evaluation metrics, and contribute to a neurosymbolic reasoning platform while shipping components at production quality.

Formación

• 3+ years of building models for business applications.
• PhD, or Master’s with 4+ years in CS/CE/ML.
• Experience with statistical modeling on large heterogeneous data.
• Fluency in Python; Rust or C++ is a plus.
• Experience with PyTorch or TensorFlow.

Responsabilidades

• Build behavioral and statistical models for security telemetry baseline.
• Design privacy-preserving representations of sensitive data.
• Define methodology and own analysis for difficult problems with evidence.
• Develop metrics and evaluation frameworks for detection performance.
• Contribute to neurosymbolic reasoning platform and ship production-grade components.
• Document work with rigorous, peer-review style reporting.

Job ID: 10583418 | Amazon.com Services LLC - A57

Amazon Leo is a constellation of Low Earth Orbit satellites that will provide low-latency, high-speed broadband network connectivity to unserved and underserved communities around the world.

Export Control Requirement

Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Key job responsibilities

• Build behavioral and statistical models that baseline normal activity across heterogeneous security telemetry, including specialized industrial-control and factory-floor data sources, so detections extend to new environments with low false-positive rates.
• Design privacy-preserving representations of sensitive security data, and verify that models and detections tuned against them remain accurate against the real data — turning data-protection guarantees into measurable, provable properties rather than assertions.
• Define the methodology and own the analysis for difficult, loosely defined problems: gather complex data across domains, select the right techniques from a range of data science methods, and justify your approach with evidence.
• Develop the metrics and evaluation frameworks that measure model and detection performance against threat actor behavior before a model is trusted in production.
• Contribute to the team's neurosymbolic reasoning platform, adapting state-of-the-art techniques from the literature and shipping components at production quality.
• Document your work with the rigor of a peer-reviewed publication, and communicate results clearly to both scientific and security-operations audiences.

A day in the life

You will move between analysis and production in the same week: profiling a telemetry source the team has never modeled, establishing what normal looks like for it, and shipping the baseline as a component detections build on. Security engineers on your team translate threat intelligence into the adversary behaviors that matter; you build and tune the models that detect those behaviors and evaluate model performance against them. You might spend a morning chasing a false-positive pattern to its statistical root cause, and the afternoon verifying that an anonymized dataset still preserves the signal a detection depends on. You will work semi-autonomously with guidance from senior scientists, backtest candidate detections against retained telemetry, and deliver scientific artifacts that ship.

About the team

Leo Space Security protects the people, facilities, hardware, and supply chain behind a global satellite constellation. The Engineering and R&D team within this organization builds the platforms and tooling the security pillar teams operate on, moving security operations from manual triage to correlation-based detection, automated response, and agentic AI. The team is composed of applied scientists, software engineers, and security engineers working across physical and digital security domains.

Inclusive Team Culture

In Amazon Security, it's in our nature to learn and be curious. Ongoing DEI events and learning experiences inspire us to continue learning and to embrace our uniqueness. Addressing the toughest security challenges requires that we seek out and celebrate a diversity of ideas, perspectives, and voices.

Training & Career Growth

We're continuously raising our performance bar as we strive to become Earth's Best Employer. That's why you'll find endless knowledge-sharing, training, and other career-advancing resources here to help you develop into a better-rounded professional.

Work/Life Balance

We value work-life harmony. Achieving success at work should never come at the expense of sacrifices at home, which is why flexible work hours and arrangements are part of our culture. When we feel supported in the workplace and at home, there's nothing we can't achieve.

Basic Qualifications

• 3+ years of building models for business application experience
• PhD, or Master's degree and 4+ years of CS, CE, ML or related field experience
• Experience with statistical modeling and analysis of large, heterogeneous datasets, including anomaly detection, time-series analysis, or behavioral baselining
• Fluency in Python; experience with a systems language such as Rust or C++ is a plus
• Experience with popular deep learning frameworks (e.g., PyTorch, TensorFlow)

Preferred Qualifications

• Experience in one or more of the following domains: access-control system and methodology, network security, application- and system-development security, security architecture and models, cryptography, and operations security
• Experience in professional software and systems development
• Publications at top-tier peer-reviewed machine learning, data mining, or security venues (e.g., NeurIPS, ICML, ICLR, KDD, CCS, USENIX Security)
• Experience with privacy-preserving machine learning, including synthetic data generation, anonymization, or differential privacy, and validating fidelity of transformed data
• Experience designing evaluation frameworks and metrics for models where ground truth requires human judgment
• Experience modeling operational or sensor telemetry, including industrial control systems (OT/SCADA), IoT, or physical-world event data
