millions of orders are fulfilled every day. Every architectural decision — solver latency, pruning strategy, network cost
calculation, inventory allocation algorithm impacts
customer delivery promise, fulfilment cost, and operational efficiency across Coupang's entire ecommerce platform in Korea and
Taiwan.
This is a rare opportunity to work at the intersection of large-scale distributed systems, real-time optimization, and ecommerce
fulfilment — with direct, measurable business impact.
What You Will Do
