Golang Engineer: Cloud Platform

COMPANY INTRODUCTION We exist to wow our customers. We know we’re doing the right thing when we hear our customers say, “How did we ever live without Coupang?” Born out of an obsession to make shopping, eating, and living easier than ever, we’re collectively disrupting the multi-billion-dollar e-commerce industry from the ground up. We are one of the fastest-growing e-commerce companies that established an unparalleled reputation for being a dominant and reliable force in South Korean commerce. We are proud to have the best of both worlds — a startup culture with the resources of a large global public company. This fuels us to continue our growth and launch new services at the speed we have been since our inception. We are all entrepreneurs surrounded by opportunities to drive new initiatives and innovations. At our core, we are bold and ambitious people that like to get our hands dirty and make a hands-on impact. At Coupang, you will see yourself, your colleagues, your team, and the company grow every day. Our mission to build the future of commerce is real. We push the boundaries of what’s possible to solve problems and break traditional tradeoffs. Join Coupang now to create an epic experience in this always-on, high-tech, and hyper-connected world. ROLE OVERVIEW The Commerce team is responsible for building next-generation cloud commerce systems that power pricing, billing, usage metering, and revenue generation for Coupang’s cloud platform. This team operates as the backbone of the cloud business, enabling accurate pricing, discounting, invoicing, and real-time usage visibility for customers. The systems are highly scalable and event-driven, ingesting and processing massive volumes of data—including customer usage events and Kubernetes-driven infrastructure signals. As the platform scales from early-stage adoption to large-scale rollout, it is expected to handle exponentially growing workloads, potentially reaching hundreds of millions to billions of events, while maintaining high performance and reliability. A key focus of this team is building financial-grade systems that ensure accuracy, consistency, and correctness in billing, pricing, and revenue computation. These systems must provide real-time insights to customers while guaranteeing precise accounting of usage and charges.
