Senior Golang Software Engineer (Infrastructure)

Mirantis, Inc.; United States; On-site; USD 140,000 - 210,000; Full time

Job summary

Mirantis, Inc. is seeking an experienced Software Engineer, Infrastructure to design and implement Infrastructure Services powering a GPU-as-a-Service platform.

You will create the control plane that enrolls bare-metal servers, provisions them, and forms multi-tenant Kubernetes clusters on high-performance hardware. Responsibilities include API design for bare-metal lifecycle, machine types, and cluster operations, plus building asynchronous workflows for enrollment, provisioning, and status

Qualifications

• Experience designing RESTful APIs or gRPC services with correct versioning and gateway patterns.
• Hands-on with Kubernetes controllers, reconcilers, and state synchronization across components.
• Proven experience in bare-metal provisioning, hardware inventory, and provisioning workflows.

Responsibilities

• Design, build, and maintain infrastructure services powering GPU-as-a-Service platform.
• Develop control plane to enroll bare-metal servers, provision, and assemble multi-tenant Kubernetes clusters on high-performance hardware.
• Own infrastructure-level APIs from Server and MachineType down to provisioning workflows and reconciliation loops.

Job description

• We are looking for an experienced Software Engineer, Infrastructure to design and implement the Infrastructure Services that power our GPU-as-a-Service platform
• You will build the control plane that turns high-level API calls into real infrastructure actions — enrolling bare-metal servers, provisioning them, and assembling them into multi-tenant Kubernetes clusters on high-performance hardware
• You will own the full lifecycle of the infrastructure‑level services—from the Server and MachineType APIs down to the provisioning workflows and reconciliation loops that keep the platform’s view of hardware consistent with physical reality
• Infrastructure API Design: Design, build, and maintain the versioned REST and gRPC APIs for bare‑metal server lifecycle, MachineType definitions, and cluster CRUD operations
• Provisioning & Workflow Development: Develop the asynchronous workflows that drive server enrollment, inspection, OS provisioning, and cluster bring‑up, exposing durable status to callers
• Implementation: Implement and maintain the consoles and interfaces that visualize hardware inventory, provisioning progress, and cluster health
• System Reliability: Design the error‑handling models, idempotency guarantees, and reconciliation loops necessary to manage long‑running provisioning operations reliably

Kubernetes Knowledge

Deep understanding of Kubernetes primitives and controller/reconciler patterns. You will be interacting with systems like k0rdent, Metal3, and Cluster API to translate high‑level API calls into infrastructure actions

Bare‑Metal Provisioning

Hands‑on experience with bare‑metal provisioning flows — BMC/Redfish, PXE/iPXE, image management, and hardware inspection

Asynchronous Systems

Experience building workflow‑driven or event‑driven systems (e.g., Temporal) where operations are long‑running and state must remain consistent across retries and failures

API Development

Strong experience designing RESTful APIs or gRPC services. You understand API versioning and gateway patternsProficiency in Go (preferred for backend/Kubernetes ecosystem)

State Reconciliation

Experience building informers or reconciliation bridges that keep an external datastore consistent with Kubernetes resource state

Multi‑Tenancy

Experience building platforms where strict data and network isolation between tenants is required

Infrastructure-as-Code

Familiarity with Terraform/OpenTofu and GitOps-driven configuration (ArgoCD or Flux)

Hardware Domain

Familiarity with GPU server hardware, DPUs/NICs, and high‑performance datacenter fabrics
