Description

Inventory Planning and Control (IPC) is seeking a Principal Scientist to join its PBC (Placement, Buying and Capacity) science team to help shape how Amazon supply chain optimizes inventory decisions in its global multi-tiered fulfillment network. PBC science team owns the core decision models in the space of S&OP Planning, Placement, Capacity Control and Buying. Our models decide when, where, and how much we should buy, flow, and hold inventories in our global fulfillment network to meet Amazon’s business goals and to make our customers happy. We do this for hundreds of millions of items and hundreds of product lines worth billions of dollars of inventory world-wide for both our Retail and Seller business. Our systems are built entirely in-house, for which we constantly develop new technologies in automated inventory planning, prediction, optimization and simulation. Our systems operate at various scales, from real-time decision system that completes thousands of transactions per seconds, to large scale distributed system that optimizes the inventory decisions over millions of products simultaneously. Your tech solution will have large impacts to the physical supply chain of Amazon, and play a key role in improving Amazon consumer business’s long term profitability. You will work on some of the most difficult problems with some of the best product managers, scientists, and software engineers in the industry.

Key job responsibilities

As a Principal Scientist in IPC, you will partner with the senior tech leaders in the organization to define the long term architecture of our decision optimization and prediction systems. You will play a key role in developing long term strategic solutions that have business impact beyond the scope of the organization. You will bring technical expertise in several technical areas of Operations Research or Machine Learning, and are able to help teams within the organization to overcome key technical blockers. You will ensure senior leaders in the organization are up to speed on important trends, tools and technologies and how they will be used to impact the business. You are able to quickly approach large ambiguous problems, turn high-level business requirements into mathematical models, identify the right solution approach. You will analyze large amounts of business data, define new metrics and business cases, design simulations and experiments, develop scientific, and collaborate with teammates in business, software, and research. Successful candidates must thrive in fast-paced environments, which encourage collaborative and creative problem solving, be able to measure and estimate risks, constructively critique peer research, and align research focuses with the Amazon's strategic needs.
