Sr.Staff-AIDataCenterArchitect

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. 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 You will lead the architectural vision for our next-generation data centers, transitioning our global footprint from traditional colocation models to high-density AI Factories. You are responsible for the physical and logical blueprint of the facility—ensuring that our "white space" can support 100kW+ racks, liquid-to-chip cooling, and the massive throughput requirements of 800G/1.6T networking. Responsibilities Facility Strategy: Design the "Basis of Design" (BOD) for hyperscale facilities, including site selection, building massing, and modular "pod" scalability. Thermal Management: Architect the transition from air-cooled data halls to Hybrid Cooling environments (Direct-to-Chip, Rear Door Heat Exchangers, and Immersion Cooling) to support high-TDP AI chips. Power & Energy: Partner with electrical engineers to design high-availability power chains (N+1/2N) capable of supporting 50MW+ of IT load per hall. Evaluate the integration of Small Modular Reactors (SMRs) or hydrogen fuel cells for onsite power. Network & Fabric Topology: Define the physical layout for OSFP-based high-radix fabrics. Optimize cabling pathways and "meet-me-room" designs to minimize signal degradation for InfiniBand and RoCE v2 compute planes. M
