Senior DevOps Engineer (Storage) - remote in the US

Doist; United States; Hybrid; USD 140,000 - 170,000; Full time

Job summary

Doist is seeking a senior DevOps engineer to own the storage stack where Kubernetes meets bare metal, standing up NFS-based high-performance storage and wiring it into clusters via CSI for GPU workloads at scale. The role spans hybrid, edge, and air-gapped deployments built on the Mirantis K0rdent stack.

The ideal candidate treats storage as infra to be automated, observed, and tuned, with IaC and GitOps by default.

Qualifications

• Senior DevOps engineer with storage as infrastructure mindset.
• Fluent in Kubernetes storage and bare-metal to disk/kernel layers.
• Experience automating with IaC and GitOps.

Responsibilities

• Integrate NFS-based high-performance storage into Kubernetes clusters via CSI and storage classes.
• Tune NFS data path for high-throughput, low-latency GPU/AI workloads.
• Deploy and operate storage services and operators; manage capacity, quotas, snapshots.
• Provision and configure storage on bare-metal hosts, including disk layout and kernel tuning.
• Deliver storage integration for k0s-based Kubernetes via CAPI and K0rdent topologies.
• Operate storage in air-gapped environments with Harbor, PKI/TLS considerations.
• Automate provisioning 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.

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.
