Amazon Leo is seeking a Senior Data Scientist to transform complex satellite, network, and customer terminal telemetry into actionable insights that drive system performance, reliability, and engineering decisions. In this role, you will work with large-scale datasets generated across satellite payloads, ground infrastructure, customer terminals, and end-to-end laboratory and on-orbit testing environments. You will develop analytical models, statistical methods, and automated data processing solutions to identify performance trends, detect anomalies, isolate issues, and support system validation and operational readiness. You will partner closely with systems, hardware, software, RF, and test engineering teams to establish meaningful performance metrics, correlate telemetry across multiple system components, and translate complex technical data into clear recommendations. Your work will directly influence engineering priorities, test strategies, system improvements, and launch readiness decisions. The ideal candidate combines strong statistical and data science expertise with practical experience analyzing complex engineering systems, processing high-volume time-series data, and developing scalable analytical solutions. Experience in satellite communications, wireless networks, or telecommunications is highly desirable. 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 - Develop and maintain scalable data processing and analytical solutions for satellite payload, ground network, customer terminal, and laboratory test telemetry. - Analyze large volumes of structured and unstructured data to identify system performance trends, anomalies, degradation, and potential failure conditions. - Correlate telemetry across satellite payloads, RF systems, networking infrastructure, customer terminals, and application-level measurements to identify relationships and isolate root causes. - Design statistical models, machine learning techniques, and predictive analytics to detect anomalies, characterize system behavior, and identify emerging reliability or performance issues. - Establish performance baselines, key performance indicators (KPIs), and statistical methodologies to evaluate system functionality, reliability, and performance across laboratory and on-orbit environments. - Analyze automated test results, test campaign data, and regression trends to identify software and hardware performance changes, recurring failures, and gaps in test coverage. - Develop dashboards, automated reports, and visualization tools that enable engineering teams and leadership to understand system health, performance, and readiness. - Apply statistical analysis and experimental design to compare software releases, hardware configurations, and system changes, quantifying their impact on end-to-end performance. - Translate complex telemetry and analytical findings into actionable engineering recommendations that influence test priorities, troubleshooting, product improvements, and operational decisions. - Collaborate across multiple engineering organizations to define data requirements, improve telemetry quality, and develop consistent analytical methodologies. - Lead the development of reusable analytical frameworks and scalable solutions that improve engineering efficiency, reduce manual investigation, and accelerate decision-making. - Mentor engineers and data scientists in statistical methods, telemetry analysis, data interpretation, and data-driven problem-solving.
