Sr. Staff Back-end Engineer II
About the Team
Coupang Intelligence Cloud (CIC) builds and operates the compute platform powering Coupang's AI/ML and large-scale workloads. We are now extending the platform from serverless container-based workload support to virtualization. We are building a VM offering on top of KVM with a tuned Linux kernel. We leverage hardware and software assisted virtualization to get baremetal-like performance within our VMs. We are building a OVN/OVS-based SDN that can be offloaded to the DPU. We are looking for a senior technical leader to drive it.
About the Role
As a Senior Staff Engineer, you will own the hypervisor, host kernel, and DPU layers of our multi-tenant VM platform. You will architect the QEMU-KVM stack, use Nvidia-DOCA for virtualization, design the SDN data plane using OVS and OVN, lead the GPU passthrough strategy for GPU and Infiniband, including NVSwitch and Shared NVLink topologies. You will be partnering closely with engineering leadership in the US, Korea, and China.
This is a hands-on individual contributor role with significant technical scope and the opportunity to shape the architecture from the ground up.
