Senior Applied Scientist, EU GTS RAS, GTS RAS

Job ID: 2830438 | Amazon Business EU Sarl

Have you ever wished to build high standard Operations Research and Machine Learning algorithms to optimize one of the most complex logistics network? Have you ever ordered a product on Amazon websites and wondered how it got delivered to you so fast, and what kinds of algorithms & processes are running behind the scenes to power the whole operation? If so, this role is for you.

The team: Global transportation services, Research and applied science
- Operations is at the heart of the Amazon customer experience. Each action we undertake is on behalf of our customers, as surpassing their expectations is our passion. We improve customer experience through continuously optimizing the complex movements of goods from vendors to customers throughout Europe.
- Global transportation analytical teams are transversal centers of expertise, composed of engineers, analysts, scientists, technical program managers and developers. We are focused on Amazon most complex problems, processes and decisions. We work with fulfillment centers, transportation, software developers, finance and retail teams across the world, to improve our logistic infrastructure and algorithms.
- GTS RAS is one of those Global transportation scientific team. We are obsessed by delivering state of the art OR and ML tools to support the rethinking of our advanced end-to-end supply chain. Our overall mission is simple: we want to implement the best logistics network, so Amazon can be the place where our customers can be delivered the next-day.

The role: Applied scientist, speed and long term network design
The person in this role will have end-to-end ownership on augmenting RAS Operation Research and Machine Learning modeling tools. They will help understand where are the constraints in our transportation network, and how we can remove them to make faster deliveries at a lower cost.

Concretely, you will be responsible for designing and implementing state-of-the-art algorithmic in transportation planning and network design, to expand the scope of our Operations Research and Machine Learning tools, to reflect the constantly evolving constraints in our network. You will enable the creation of a product that drives ever-greater automation, scalability and optimization of every aspect of transportation, planning the best network and modeling the constraints that prevent us from offering more speed to our customer, to maximize the utilization of the associated resources. The impact of your work will be in the Amazon EU global network.

The product you will build will span across multiple organizations that play a role in Amazon’s operations and transportation and the shopping experience we deliver to customer. Those stakeholders include fulfilment operations and transportation teams; scientists and developers, and product managers. You will understand those teams constraints, to include them in your product; you will discuss with technical teams across the organization to understand the existing tools and assess the opportunity to integrate them in your product. You will also be challenged to think several steps ahead so that the solutions you are building today will scale well with future growth and objective (e.g.: sustainability). You will engage with fellow scientists across the globe, to discuss the solutions they have implemented and share your peculiar expertise with them.

This is a critical role and will require an aptitude for independent initiative and the ability to drive innovation in transportation planning and network design. Successful candidates should be able to design and implement high quality algorithm solutions, using state-of-the art Operations Research and Machine Learning techniques. You will have the opportunity to thrive in a highly collaborative, creative, analytical, and fast-paced environment oriented around building the world’s most flexible and effective transportation planning and network design management technology.

1. Engage with stakeholders to understand what prevents them to build a better transportation network for Amazon
2. Review literature to identify similar problems, or new solving techniques
3. Build the mathematical model representing your problem
4. Implement light version of the model, to gather early feedback from your stakeholders and fellow scientists
5. Implement the final product, leveraging the highest development standards
6. Share your work in internal and external conferences
7. Train on the newest techniques available in your field, to ensure the team stays at the highest bar

- Master Degree and several years of experience or PhD in Operations Research, Machine Learning, Statistics, Applied Mathematics, Computer Science or other field related to algorithms
- Experience in designing and implementing models and algorithms for one or more 1) Combinatorial optimization problems (e.g., scheduling, vehicle routing, and facility location), 2) Continuous optimization problems (e.g., linear programming, convex programming, non-convex programming)
- Experience implementing algorithms in object oriented programming languages (C++/ Java)
- Publication in top-tier peer-reviewed conferences or journals

- Comfortable to tradeoff complexity and efficiency of solution methodologies, according to the requirements of the problem. Ability to deal with ambiguity.
- Ability to communicate at a level appropriate to the audience.
- 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.
- Experience implementing models and analysis tools through the use of high-level modeling languages (e.g. R).
- Experience collecting, processing and combining big data with appropriate methodologies (e.g. SQL, Hadoop, pySpark)
