Senior DevOps Engineer (Storage) - remote in the US

Mirantis is the Kubernetes-native AI infrastructure company, enabling organizations to build and operate scalable, secure, and sovereign infrastructure for modern AI, machine learning, and data-intensive applications. The role of Senior DevOps Engineer involves deploying, integrating, and operating high-performance storage for GPU-accelerated compute and AI platforms, focusing on automation and observability.

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

Requirements:

• 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)
