Senior Software Engineer (Storage)

Mirantis, Inc.; United States; Hybrid; USD 150,000 - 210,000; Full time

Job summary

Mirantis, Inc. is seeking an experienced software engineer to design and implement high-performance storage provisioning for GPU/AI workloads.

You will build control-plane services, CSI drivers, and tooling to connect storage systems to Kubernetes workloads across hybrid, edge, and air-gapped environments. You will work with Dell PowerScale, VAST, and similar storage platforms, and contribute to declarative provisioning workflows, data-path instrumentation, and secure, scalable pipelines using

Qualifications

• 5+ years of software development, including production systems, with Go as a primary language.
• Experience building or integrating storage systems (distributed, scale-out, NAS or object) at scale.
• Proven experience designing storage for GPU/AI workloads and high-security air-gapped environments.

Responsibilities

• Design and build the software that provisions, integrates, and operates high-performance storage for GPU-accelerated compute and AI platforms.
• Develop control-plane services, drivers (CSI), and tooling that connect storage to Kubernetes workloads across hybrid, edge, and air-gapped deployments.
• Integrate storage platforms into automated, declarative provisioning workflows and build observability tooling.
• Deliver IaC and GitOps pipelines for storage configuration and lifecycle, and support bare-metal and hybrid provisioning.

Job description

• Design and build the software that provisions, integrates, and operates high-performance storage for GPU-accelerated compute and AI platforms
• You will develop the control-plane services, drivers, and tooling that connect enterprise and scale-out storage systems to Kubernetes-based workloads across hybrid, edge, and air-gapped deployments built on the Mirantis K0rdent stack
• Design and build control-plane services, drivers (e.g., CSI), and tooling that provision, configure, and operate storage for Kubernetes-based AI/compute workloads
• Integrate high-performance storage platforms — Dell PowerScale, VAST, and comparable systems — into automated, declarative provisioning workflows
• Build data-path, telemetry, and observability tooling to diagnose and resolve performance, reliability, and scaling issues
• Write production-quality software — primarily in Go — with strong testing, code review, and operational rigor
• Deliver infrastructure-as-code (Terraform/OpenTofu) and GitOps-driven pipelines (ArgoCD or Flux) for storage configuration and lifecycle
• Support bare-metal and hybrid provisioning where storage intersects host and cluster bring-up
• Deliver storage integration for k0s-based Kubernetes via Cluster API (CAPI) and K0rdent management/child cluster topologies
• Architect storage software for fully disconnected (air-gapped) environments, including local artifact/mirror connectivity (Harbor) and PKI/TLS considerations

We are looking for a software engineer who thinks in systems and data paths — someone who can reason about throughput, latency, consistency, and failure across a storage stack, then express that understanding as clean, testable GoThe right candidate has built production software against real storage systems (whether enterprise NAS, scale-out, or object), understands what makes storage fast and reliable at scale, and prefers declarative automation over manual operationsYou should be self-directed, comfortable owning ambiguous problems end to end, and effective communicating technical decisions across teamsSolid understanding of storage fundamentals: file/block/object models, throughput and latency behavior, caching, consistency, and failure modesHands-on experience with high-performance storage platforms such as Dell PowerScale, VAST, or comparable technologiesExperience with Kubernetes storage (CSI, persistent volumes, storage classes) and infrastructure-as-codeStrong written and verbal communication with technical audiences5+ years of software development, including production systems, with Go as a primary language5+ years building or integrating storage systems (distributed, scale-out, NAS, or object) at scaleExperience developing storage for GPU/AI workloads (high-throughput data pipelines, GPUDirect Storage)Proven experience in sovereign or high-security air-gapped environmentsExperience with the Mirantis K0rdent stack (K0rdent Enterprise, K0rdent AI, k0s, MKE) and Cluster APIProficiency in Python and/or Rust in addition to Go
