How would you build the next generation of mission critical systems and services that power the ability to send, store and manage billions of products across the globe on behalf of our selling partners?
Fulfillment by Amazon (FBA) is the Amazon service for world-wide sellers that offers access to Amazon’s vast distribution network as a service. Similar to how AWS provides infrastructure as a service, FBA allows sellers to only pay for what they use, creating a seamless experience to leverage our world-class infrastructure. Sellers, from Fortune 50 companies to hundreds of thousands of small businesses and entrepreneurs, in 135 countries worldwide, rely upon our world-leading technology to grow and thrive on Amazon’s Marketplaces.
As a leader within FBA, you will provide both strategic and tactical oversight to build the features and functionality required to have the best in class offering for sellers. This leader will create mechanisms to drive optimal seller behavior for FBA inventory management, reducing total supply chain costs and making it easier for sellers to get their inventory close to customers, delivering more items with a Prime delivery promise. This leader will invent new ways to deliver value for sellers and their products, while leveraging the scale and innovation of technology from across the Amazon family, including AWS.
We operate as a startup within Amazon, providing our team great flexibility in product and technology direction. Come, join us and build the future!
Key job responsibilities
You will solve ambiguous business problems and map them to elegant technical solutions
* You will use object-oriented concepts, algorithms and data structures to build systems at Amazon scale
* You will design, launch, and re-architect multi-tier systems with large amounts of data
* You will quickly adapt to fast-paced development environment with bias towards simple and extensible code
A day in the life
You might start your day reviewing customer feedback and operational metrics for a recently launched seller experience. You could then work with a UX designer and product manager to refine a new workflow that helps sellers understand their inventory placement and delivery options.
Later, you may collaborate with backend and science engineers to define an API contract for a new optimization capability, review a teammate’s design or code change, and spend focused development time building and testing a new experience.
The problems we solve often span UX, front-end architecture, distributed services, and complex supply-chain decisions. You will have significant ownership over how those capabilities ultimately come together as a simple experience for our sellers.
About the team
The FBA Placement organization owns the technology that determines where and when seller inventory enters Amazon’s fulfillment network.
Our systems evaluate factors including fulfillment cost, customer delivery speed, available capacity, seller preferences, and network constraints to provide sellers with inbound options and recommendations. These decisions have significant impact on both the seller experience and Amazon’s fulfillment network.
Our front-end experiences are where these sophisticated optimization systems become tangible for sellers. Our goal is to make complex supply-chain decisions understandable and actionable-helping sellers confidently choose the right inbound options without needing to understand the complexity of the systems operating behind them.
We are a multidisciplinary organization spanning front-end and backend engineering, product, UX, and applied science. We operate with a high degree of ownership and encourage engineers to influence both the customer experience and the underlying technical architecture.
If you enjoy turning complex problems into simple customer experiences, building products at global scale, and working across the full technology stack, FBA Placement offers a unique opportunity to make an impact.
