Senior DevOps Engineer (Storage) - remote, US/EU

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, 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.
• Provision and configure storage on bare-metal hosts, including disk layout, drivers, and kernel/network tuning.
• 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.

Qualifications

• 5+ years in DevOps, SRE, or infrastructure operations, with strong hands-on experience operating Kubernetes storage (CSI, persistent volumes, storage classes) in production.
• Experience integrating and operating NFS-based high-performance / NAS storage, including data-path tuning.
• Bare-metal operations experience: host provisioning, disk/storage configuration, and Linux storage and networking fundamentals.
• Proficiency with infrastructure-as-code (Terraform/OpenTofu) and GitOps-driven configuration.
• Scripting/automation skills (e.g., Bash, Python, or Go).
• Strong written and verbal communication with technical audiences.

Preferred

• 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.
