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.
As a Staff Backend Engineer, you will act as a technical leader, translating complex business requirements into scalable architecture and distributed systems. You will design and build low-latency, high-throughput backend services that can support multi-tenant cloud environments, ensure reliability under rapid growth, and maintain strict correctness in revenue-critical workflows.
