Responsibilities
- 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
- 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
- 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
Skills
- 7+ years of experience in SRE or infrastructure operations
- 5+ years of building/operating distributed production Storage systems at scale
- Hands-on with High Performance Storage solutions (VAST, Weka, DDN, PowerScale)
- Linux and Kubernetes storage fundamentals (NFS, CSI)
- 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 paths
- Experience 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
