Job summary

Mirantis is seeking a senior DevOps/M storage engineer to own the storage layer where Kubernetes meets bare metal, focusing on NFS-based high-performance storage integration with CSI and clusters. You will optimize data paths, automate provisioning, and ensure reliability across hybrid and air-gapped deployments.

The role requires deep Linux storage knowledge, hands-on with NAS systems, and experience with Kubernetes storage internals.

Qualifications

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

Responsibilities

• Integrate NFS-based high-performance storage 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 and kernel parameter optimization.
• Deliver storage integration for k0s-based Kubernetes via Cluster API (CAPI) and K0rdent management/child cluster topologies.
• Operate storage in air-gapped environments, including Harbor connectivity and PKI/TLS considerations.
• Automate storage provisioning and configuration with Terraform/OpenTofu and GitOps (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.
