About The Position

Mirantis is seeking a Senior Software Engineer specializing in Golang to design and build software for provisioning, integrating, and operating high-performance storage for GPU-accelerated compute and AI platforms. The role involves developing 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. The ideal candidate will have a strong understanding of systems and data paths, including throughput, latency, consistency, and failure across a storage stack, and be proficient in writing clean, testable Go code. Experience with production storage systems, understanding of scalable storage performance and reliability, and a preference for declarative automation are essential. The role requires a self-directed individual comfortable owning ambiguous problems end-to-end and effectively communicating technical decisions across teams.

Requirements

7+ years of experience with Golang in production systems
5+ years of experience building distributed production systems at scale
5+ years of Kubernetes experience as a developer, with Infrastructure as a Code approach
Linux and Kubernetes storage fundamentals (NFS, CSI)

Nice To Haves

Proficiency in Python
Experience developing or integrating High Performance Storage for GPU/AI workloads (high-throughput data pipelines, GPUDirect Storage).
Proven experience in sovereign or high-security air-gapped environments.

Responsibilities

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.
