Data Scientist, North America Sort Centers, Amazon Transportation Services
As a Data Scientist II, you will own the end-to-end Machine learning Operation cycle: Design, build, and ship machine learning and/or optimization models that directly shape Amazon's middle miles planning decisions. You will own end-to-end delivery — from problem framing with business partners, through modeling and validation, to deployment in internal model hosting platform and integration with downstream planning tools.
You will work on problems such as:
Long- and short-horizon forecasting
Network and capacity optimization
GenAI / agentic systems
Defect prevention and adaptive planning
You will partner closely with Engineering, Product, Engineering, and stakeholders to translate ambiguous operational pain points into measurable model outcomes.
Key job responsibilities
- Design and implement complex ML and optimization solutions (forecasting, MIP/LP, simulation, Deep learning / foundation model)
- Drive end-to-end delivery of scalable models. From data exploration and feature engineering through training, evaluation, deployment, and post-launch monitoring;
- Develop new modeling patterns and analytical frameworks for forecasting (multivariate, hierarchical, causal-DAG, model-chaining) and optimization;
- Build robust model validation, backtesting, and monitoring pipelines; identify and eliminate sources of leakage, bias, and silent failure;
- Define and own model performance metrics (e.g., WAPE) tied to business outcomes;
- Partner with Data Engineering and Software Development to productionize models and define I/O contracts, packaging, and model CI/CD;
- Excellent communication to present findings, tradeoffs, and recommendations clearly to stakeholders and senior leadership.
