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 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, deeply versed in Linux storage and networking fundamentals down to the 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.

Bare-metal hardware experience is a strong plus, but deep Linux storage knowledge is essential.

Responsibilities

• 1. Storage Integration & Operation
• 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, 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.
• 2. Linux Platform & System Integration
• 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.
• 3. Automation & Observability
• Automate storage provisioning and configuration with infrastructure-as-code (Terraform/Open Tofu) and Git Ops pipelines (Argo CD 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 Dev Ops, SRE, or infrastructure operations, with strong hands‑on experience operating Kubernetes storage (CSI, persistent volumes, storage classes) in production.
• Linux Storage & Networking

Core: Strong expertise in Linux storage and networking fundamentals (e. g., LVM, file systems, kernel tuning, network/storage drivers, and block device management).

• High‑Performance NAS Expertise: Proven experience integrating, tuning, and operating NFS-based high-performance / NAS storage data paths.
• Automation & Git

Ops: Proficiency with infrastructure-as-code (Terraform/Open Tofu) and Git Ops-driven configuration (Argo CD or Flux).

• Scripting: Solid scripting/automation skills (Go, Python, Bash).
• Communication: Strong written and verbal communication with technical audiences.
• Preferred
• Bare‑Metal Experience: Hands‑on experience with bare‑metal host provisioning, raw disk/hardware layout, and physical server storage configurations.
• Hands‑on experience with VAST and/or Dell Power Scale.
• Experience with GPUDirect Storage and RDMA/Ro CE 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.
• Additional Information

What does Mirantis offer you?

• - Work with an established Silicon Valley leader in the cloud infrastructure industry;
• - Work with exceptionally passionate, talented and engaging colleagues, helping Fortune 500 and Global 2000 customers implement next‑generation cloud technologies;
