We leverage the power of digital assets and blockchain to build an inclusive financial ecosystem to advance the freedom of money and improve financial access for people around the world. ## About the Role We are building our own IDC infrastructure from the ground up. As a Senior Infrastructure Engineer, you will lead the architecture, buildout, and operations of our colocation data center — from rack layout to the on-prem Kubernetes platform. You build it, you own it. This is a true greenfield role with no legacy baggage and a high degree of architectural ownership. Your core expertise will center on three pillars: building physical infrastructure from zero, running production-grade self-hosted Kubernetes, and hybrid-cloud interconnect. As the platform matures, you'll help drive the next phase of cross-cloud and scale-out buildout. ### Responsibilities - Design rack layout, network topology, and overall configuration for colocation - Design and implement an isolated Out-of-Band (OOB) management network (BMC, IPMI, Redfish) with full security hardening - Coordinate with colocation and hardware vendors — servers, switches, cross-connects, uplinks, remote hands, and cage/rack administration - Build bare-metal automation for fleet-wide zero-touch OS provisioning (MAAS / Tinkerbell / Cluster API) - Set up production-grade self-hosted Kubernetes clusters from scratch and maintain the core stack: Cilium (CNI), GitOps (ArgoCD), etc. - Own cluster lifecycle: upgrades, scaling, node maintenance, incident response - Write SOPs, runbooks, and post-mortems; participate in 24×7 on-call rotation - Establish hybrid-cloud interconnect between IDC and public cloud (VPN / Direct Connect / peering) - Pave the way for scale-out: GPU workloads (NVIDIA GPU Operator, passthrough, MIG) and VM workloads running alongside containers (KubeVirt or similar) ### Requirements - 5+ years in data center / infrastructure / platform engineering - Hands-on experience building physical infrastructure from scratch: rack layout, network topology, server commissioning, and coordinating cross-connects and remote hands with colo / vendors - Practical experience designing and operating OOB management networks (BMC, IPMI, Redfish) - Have stood up production-grade self-hosted Kubernetes from scratch, and can independently debug cluster-level issues (CNI, CSI, storage) - Strong Linux systems administration and performance tuning (kernel, networking, storage I/O) - Bare-metal automation experience with at least one of: MAAS, Tinkerbell, Cluster API - Proficient with Terraform, Ansible, and at least one scripting language (Python / Go / Bash) - Experience with Cisco network and related techniques (VLAN, LACP/LAG, BGP, ACL, etc) - Experience with Palo Alto firewall configuration - Experience with storage systems (NetApp, Dell EMC, Pure Storage) - Fluent in English or Mandrain ### Nice to Have - High-density racks (30kW+) and 400G+ networking experience - Familiarity with immutable OS (Talos Linux / Flatcar / Bottlerocket) - Proficiency across both AWS and GCP; cross-cloud data migration experience - Experience building storage or Bigdata / offline data clusters - Virtualization experience (KubeVirt or similars) - Exposure to NVIDIA GPU Operator and K8s GPU workloads - CKA / CKS certification - CCNP / CCIE certification - Professional-level Japanese
