Software Development Engineer Ii, Simex

Looking for an exciting challenge to accelerate your career? Are you customer obsessed? Imagine being part of a team that predicts inventory flows for Amazon’s worldwide supply chain. Amazon’s worldwide inventory planning involves many algorithms to buyinventory in the right quantities, at the right frequencies, from the right vendors, and assigning to the best warehouse to fulfill customer demand forecast. Our massive simulation system lives at the heart of these algorithms, keeping up with the rapid paceof optimization improvements and simulating how they interact with each other. We simulate what these systems will do for months into the future, predicting inventory flows across the network for both labor planning and AB test experimentation, end-to-endfrom vendors to customers.
The Amazon Supply Chain Optimization Technology organization is looking for a highly motivated software development engineers (SDE). SCOT is a unique opportunity to both create and see the direct impact of your work on billions of dollars’ worth of inventory,in one of the world’s most advanced supply chains, and at massive scale.
As an SDE in SCOT’s Simulation and Experimentation (SimEx) team, you will work closely with some of the brightest software engineers, scientists, economists, and product managers, to solve highly complex supply chain challenges. You will work on one of thelargest distributed systems in the world in order to support new use cases and design its future state, you will think of how we can leverage newer AWS technologies (specifically technologies such as ECS and EMR), that will allow our next generation systemto run elastically at a much larger scale and on demand, as well as define new frameworks (data APIs, plug and play technology) that will allow supply chain teams to integrate their components in simulation in a low touch manner. You will be responsible forbuilding key technology programs across our SimEx tool set, successfully delivering new functionality and meeting program goals. You will design, implement, test, write library code and own Monte Carlo Simulation system for Amazon Supply Chain, using object-oriented,distributed programming, and other AWS services and more in Linux environment.
Finally, here are some more reasons you might find this opportunity exciting:

- Being part of a team that is at the heart of the most sophisticated supply chain and decision making system on the planet.
- Working at the intersection of science and engineering to simulate and predict future supply chain flows in order to ultimately impact Amazon user experience (by helping supply chain teams run experiments that allow for speed and same day availability forexample), saving hundreds of millions of dollars using cutting edge science and technology on the way.
- Being part of a team that values creativity and welcomes outside of the box thinking (thinking big).
- Being part of a team with a high emphasis on a positive work culture of collaboration.
- Being part of a fast growing team with many growth opportunities.

**BASIC QUALIFICATIONS**
- 2+ years of non-internship professional software development experience
- Programming experience with at least one modern language such as Java, C++, or C# including object-oriented design
- 1+ years of experience contributing to the architecture and design (architecture, design patterns, reliability and scaling) of new and current systems

**PREFERRED QUALIFICATIONS**
- Understanding of Amazon technologies like DynamoDB, AWS, S3, EMR, ECS
- Understanding of integration technologies like web services, messaging queues
- Understanding of No-Sql and RDBMS database technologies
