About the Team

Our team is responsible for several key capabilities associated with a trip or a delivery: from real-time tax rate calculation, to issuing all related documents that are meaningful for our riders and partners (receipts, invoices, tax reports), to providing our partners with real-time and easy access to their tax data from within 3rd party partner applications like Intuit, Stride and HR Block. The platforms that we build need to be highly scalable (handling data from dozens of millions of trips per day), highly available (our riders and partners need access to their documents & data 24/7) and highly flexible (Uber is operating in 80+ countries around the world, each with its own compliance requirements)
