Senior Software Engineer (Storage) - remote in the US

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. The Senior Software Engineer will design and build software for high-performance storage in AI platforms, focusing on control-plane services and integration with Kubernetes-based workloads.

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

Requirements:

• 5+ years of software development, including production systems, with Go as a primary language
• 5+ years building or integrating storage systems (distributed, scale-out, NAS, or object) at scale
• Hands-on experience with high-performance storage platforms such as Dell PowerScale, VAST, or comparable technologies
• Solid understanding of storage fundamentals: file/block/object models, throughput and latency behavior, caching, consistency, and failure modes
• Experience with Kubernetes storage (CSI, persistent volumes, storage classes) and infrastructure-as-code
• Strong written and verbal communication with technical audiences
• Proficiency in Python and/or Rust in addition to Go
• Experience with the Mirantis K0rdent stack (K0rdent Enterprise, K0rdent AI, k0s, MKE) and Cluster API
• Experience developing storage for GPU/AI workloads (high-throughput data pipelines, GPUDirect Storage)
• Proven experience in sovereign or high-security air-gapped environments
