Senior DevOps Engineer (Storage) - remote, US/EU
About The Position
Mirantis is seeking a Senior DevOps Engineer specializing in Storage to deploy, integrate, and operate high-performance storage solutions for GPU-accelerated compute and AI platforms. This role involves managing the storage layer where Kubernetes intersects with bare metal, including setting up NFS-based storage, integrating it into clusters via CSI, and optimizing it for demanding AI workloads. The work will encompass hybrid, edge, and air-gapped deployments built on the Mirantis K0rdent stack. The ideal candidate views storage as infrastructure to be automated, observed, and tuned, possesses strong Kubernetes storage expertise, is comfortable working with bare metal systems, and excels at ensuring high-performance NAS operations under pressure. A preference for infrastructure-as-code and GitOps practices, self-directed problem-solving, setting operational standards, and clear cross-team communication are essential.
Requirements
- 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.
Nice To Haves
- 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.
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.
Benefits
- Professional development and training
- Attend conferences and working groups
- Company outings, happy hours, hackathons, and tech talks
- Competitive compensation package with a strong benefits plan
