What you'll do at

We need super smart engineers from all levels to help us build one of the best engineered e-commerce platform in the world (big talk we know, but that is our goal!). Our engineers combine creativity, curiosity, and drive to continuously perfect and revolutionize Jet from the inside out. We are looking to bring more intellectually curious engineers who are passionate about technology in general (Jet is a technology first company and prides itself on its culture of learning and knowledge sharing and we want all our engineers to be as passionate as we are!) 

What you will be Working on 

Our high-volume inventory system tracks the available quantities of all our items of sale, known as stock-keeping units (SKUs). We cover, Walmart owned warehouses and all our partner merchant warehouses, along with quantities reserved from in-flight orders.  

Customers expect that the availability of an item for sale is a true and accurate representation of what that retailer can fulfill. The Unified Inventory system’s purpose is to ensure that this expectation is met. As Walmart builds deeper and richer digital experiences with its customers, this expectation becomes more complex, and it is the role of the Unified Inventory team to abstract away this complexity for downstream systems. 

 We are looking for an exceptionally talented Data Engineer to envision and apply machine learning to tackle challenges like predicting inventory availability and cancellations.
