Company Description About MirantisMirantis is the Kubernetes-native AI infrastructure company, enabling organizations to build and operate scalable, secure, and sovereign infrastructure for modern AI, machine learning, and data-intensive applications. By combining open source innovation with deep expertise in Kubernetes orchestration, Mirantis empowers platform engineering teams to deliver composable, production-ready developer platforms across any environment—on-premises, in the cloud, at the edge, or in sovereign data centers. As enterprises navigate the growing complexity of AI-driven workloads, Mirantis delivers the automation, GPU orchestration, and policy-driven control needed to manage infrastructure with confidence and agility. Committed to open standards and freedom from lock-in, Mirantis ensures that customers retain full control of their infrastructure strategy.Job Description Overview Deploy, integrate, and operate high-performance storage for GPU-accelerated compute and AI platforms. You will own the storage layer where Kubernetes meets bare metal — standing up NFS-based high-performance storage, wiring it into clusters via CSI, and tuning it to keep data flowing to GPU workloads at scale. Work spans hybrid, edge, and air-gapped deployments built on the Mirantis K0rdent stack.About the Role We are looking for a senior DevOps engineer who treats storage as infrastructure to be automated, observed, and tuned — not hand-managed. The right candidate is fluent in Kubernetes storage, deeply versed in Linux storage and networking fundamentals down to the kernel and NFS-client layer, and knows how to make high-performance NAS actually perform under demanding workloads. You should reach for infrastructure-as-code and GitOps by default,



be self-directed in diagnosing performance and reliability issues end to end, set operational standards for others to follow, and communicate clearly across teams. Bare-metal hardware experience is a strong plus, but deep Linux storage knowledge is essential.Responsibilities 1. Storage Integration & Operation Integrate NFS-based high-performance storage (e.G., VAST, Dell PowerScale) into Kubernetes clusters via CSI, storage classes, and persistent volumes.Tune the NFS data path — mount options, nconnect/RDMA, Linux client, and network settings — for high-throughput, low-latency GPU/AI workloads.Deploy and operate storage services and operators; manage capacity, quotas, snapshots, and lifecycle.2. Linux Platform & System Integration Configure and optimize Linux systems for storage workloads, including driver setup, file system layout, network tuning, and kernel parameter optimization.Deliver storage integration for k0s-based Kubernetes via Cluster API (CAPI) and K0rdent management/child cluster topologies.Operate storage in fully disconnected (air-gapped) environments, including local artifact/mirror connectivity (Harbor) and PKI/TLS considerations.3. Automation & Observability Automate storage provisioning and configuration with infrastructure-as-code (Terraform/OpenTofu) and GitOps pipelines (ArgoCD or Flux).Build monitoring, alerting, and observability for storage performance, capacity,



and health.Diagnose and resolve performance, reliability, and scaling issues across the storage stack.Qualifications Required qualifications:7+ years of experience in SRE or infrastructure operations5+ years of building/operating distributed production Storage systems at scaleHands-on with High Performance Storage solutions (VAST, Weka, DDN, PowerScale)Linux and Kubernetes storage fundamentals (NFS, CSI)Preferred:Bare-metal experience: hands-on experience with bare-metal host provisioning, raw disk/hardware layout, and physical server storage configurations.Hands-on experience with VAST and/or Dell PowerScale.Experience with GPUDirect Storage and RDMA/RoCE data pathsExperience with the Mirantis K0rdent stack (K0rdent Enterprise, K0rdent AI, k0s, MKE) and Cluster API.Familiarity with other storage backends (Ceph, object/S3) and CSI driver operations.Proven experience in sovereign or high-security air-gapped environments.Additional Information What does Mirantis offer you?
