Research Scientist, SCOT Fulfilment Topology

Job ID: 1884713 | Amazon.com Services LLC

DESCRIPTION

Job summary
SCOT Network Topology science team focuses on research areas of forecasting and optimization models that determine Amazon outbound network design as we transition to relying on our internal carrier network and accelerate one-day delivery speed. We utilized models from various science disciplines such as: Mixed Integer , Random Forest (or other ML techniques), probabilistic model, stochastic economic analysis, to name a few.

In addition to network, we also use and techniques to evaluate new facilities recommendation for long term estimates, We use to approximate the network, and simulation of how our choices will perform.

We are looking for a Research Scientist who has a knowledge of analyzing fulfillment data using statistics and machine learning models . Those who are strong in space should have a breadth of other ML experience in a production environment using techniques. This role will focus on expanding our reach to analyze various fulfillment and for Amazon's network worldwide.

To help describe some of our challenges, we created a short video about at Amazon - http://bit.ly/amazon-scot



A day in the life
A scientist in the team is expected to do 4 mixes of works: (i) Research development - this can be new model or existing model feature enhancement (40-50%), (ii) Ad-hoc study - pulling data or create simple prototype to answer a business questions (20-30%) and (iii) Operational (20-30%) - this includes meeting with stakeholders for feedback, learning new things, or team meetings

About the team
SCOT Network Topology science team focuses on research areas of forecasting and optimization models that determine Amazon outbound network design as we transition to relying on our internal carrier network and accelerate one-day delivery speed. There are various strategic questions the team is attempting to answer, such as: what is the impact of placement on outbound cost and delivery speed? What is the optimal network design given capacity constraints? How can we forecast accurately fulfillment pattern for different customer clusters?. If you are interested in diving into a multi-discipline, high impact space this team is for you.

Our team is a mixture of Software Engineers, Operations Research Scientists, Applied Scientists, Business Intelligence Engineers and Product Managers.
