Design and implement scalable and reliable data‑science solutions to support or automate decision making across Amazon. Apply a range of techniques—from statistical and econometric modeling to machine learning, NLP, and neural networks—to solve complex business problems where the solution approach is unclear. Acquire data via SQL/ETL, integrate with Oracle, Red Shift, and Spark, and build models that meet stringent accuracy, reliability, and computational requirements throughout the production pipeline.

• Acquire and transform data using SQL and ETL queries; import data through custom interfaces to Oracle, Red Shift, and Spark.
• Build and validate models across a portfolio of techniques including statistical, mathematical, econometric, network, social‑network, NLP, machine learning, genetic algorithms, and neural networks.
• Evaluate models against business‑defined KPIs and alternative approaches; ensure compliance with computational demands and production reliability.
• Analyze data for trends, anomaly detection, and data quality, applying appropriate transformations.
• Collaborate with stakeholders to define model requirements and communicate results effectively.

• Master’s degree (or equivalent) in Statistics, Applied Mathematics, Economics, Engineering, Computer Science, or a related field, plus one year of relevant experience; alternatively, a bachelor’s degree with five years of progressive post‑baccalaureate experience may be accepted.
• At least one year of experience in: building statistical and machine‑learning models with large, multi‑source datasets; writing SQL scripts for analysis and data migration; and applying specialized modeling software with R, Python, or MATLAB.
• Proven ability to design end‑to‑end data‑science solutions that are accurate, reliable, and scalable.

• Experience with AWS services (e.g., Red Shift, Athena, EMR) is a plus.
• Strong communication skills and a collaborative mindset.
• Prior exposure to fairness, equity, or audit‑tracking in model development.
