Have you ever wondered how Amazon delivers timely and reliably hundreds of millions of packages to customer’s doorsteps? Are you passionate about data and mathematics, and hope to impact the experience of millions of customers? Are you obsessed with designing simple algorithmic solutions to very challenging problems?
If so, we look forward to hearing from you
Amazon Transportation Services is seeking a Senior Applied Scientist to be based in the EU Headquarters in Luxembourg. As a key member of the Research Science Team of ATS operations, this person will be responsible for designing algorithmic solutions based on data and mathematics for optimizing the middle-mile Amazon Transportation Network. The successful applicant will ensure that our end-to-end strategies in terms of customer demand fulfillment, routing, consolidation locations, linehaul/airhaul/sea options and last-mile transportation are streamlined and optimized.
Key job responsibilities
This critical role requires an aptitude for independent initiative and decision-making, the ability to drive innovation in Transportation modelling and optimization across Amazon’s expanding European network and linking into global initiatives and expansion strategies.
- Design and prototype algorithmic solutions for standardized processes.
- Lead complex time-bound, long-term as well as ad-hoc transportation modelling analyses to help management in decision making.
- Partner with the planning, linehaul/airhaul and sort center operations teams, while working closely with last-mile, supply chain, and global delivery departments for modeling and optimizing the transportation network of EU.

About the team
We are a global science and tech team for developing cutting-edge optimization models for Amazon's middle mile network. We are owning the entire lifecycle of tech products from idea to production-use and deploy our tools on a worldwide basis. Our team is composed of a wide variety of tech roles including scientists, data engineers and business intelligence engineers.
- Detailed knowledge of optimization methods including linear and mixed-integer programming, network modeling, constraint programming, approximation algorithms, and advanced heuristic techniques.
- Expertise on MIP strategies to customize and leverage commercial algorithms and adapt them as required.
- Detailed knowledge of forecasting techniques with time-series tools, including ARIMA models, exponential smoothing, LSTM, CNNs.
- Expertise on policy optimization techniques, including reinforcement learning, deep Q-learning, bandits, and online optimization.
- Experience implementing models and analysis tools through the use of high-level modeling languages (e.g. R, Matlab as examples).
- Experience collecting, processing and combining big data with appropriate methodologies (e.g. Hadoop, Map-Reduce)
