Senior DevOps Engineer (Storage) - remote in the US

Company Description

About Mirantis

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. By combining open source innovation with deep expertise in Kubernetes orchestration, Mirantis empowers platform engineering teams to deliver composable, production-ready developer platforms across any environment—on-premises, in the cloud, at the edge, or in sovereign data centers. As enterprises navigate the growing complexity of AI-driven workloads, Mirantis delivers the automation, GPU orchestration, and policy-driven control needed to manage infrastructure with confidence and agility. Committed to open standards and freedom from lock-in, Mirantis ensures that customers retain full control of their infrastructure strategy.

Job Description

Overview

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

About the Role

We are looking for a senior DevOps 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 GitOps 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

1. Storage Integration & Operation

• 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.

2. Bare Metal & Platform

• 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.

3. Automation & Observability

• 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.
