Senior DevOps Engineer; Storage - remote, US​/EU

Senior Dev Ops Engineer (Storage)

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 k spans hybrid, edge, and air-gapped deployments built on the Mirantis K0rdent stack.

We are looking for a senior Dev Ops engineer who treats storage as infrastructure to be automated, observed, and tuned — not hand-managed. The right candidate is fluent in Kubernetes storage, comfortable on bare metal down to the disk, 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 Git Ops 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.

Responsibilities:

• Integrate NFS-based high-performance storage (e.g., VAST, Dell Power Scale) 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/Open Tofu) and Git Ops 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.

• 5+ years in Dev Ops, 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/Open Tofu) and Git Ops-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 Power Scale.
• 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.
