Mirantis is seeking an experienced Senior Software Engineer to design and implement Infrastructure Services powering their GPU-as-a-Service platform. You will own the full lifecycle of infrastructure-level services, building the control plane that translates 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.
Key responsibilities include:
• Infrastructure API Design: Design, build, and maintain versioned REST and gRPC APIs for bare-metal server lifecycle, MachineType definitions, and cluster CRUD operations.
• Provisioning & Workflow Development: Develop asynchronous workflows that drive server enrollment, inspection, OS provisioning, and cluster bring-up, exposing durable status to callers.
• Implementation: Implement and maintain consoles and interfaces that visualize hardware inventory, provisioning progress, and cluster health.
• System Reliability: Design error-handling models, idempotency guarantees, and reconciliation loops necessary to manage long-running provisioning operations reliably.
You will interact with systems like k0rdent, Metal3, and Cluster API to translate infrastructure requirements into actionable operations. This role requires deep ownership of infrastructure patterns and the ability to design systems that handle complex, long-running operations with strong consistency guarantees.
Mirantis is a Kubernetes-native AI infrastructure company enabling organizations to build and operate scalable, secure, and sovereign infrastructure for modern AI and machine learning applications. The company combines open-source innovation with deep Kubernetes expertise to help platform engineering teams deliver production-ready developer platforms across any environment.
REQUIREMENTS:
• Strong experience designing RESTful APIs or gRPC services; understanding of API versioning and gateway patterns
• Proficiency in Go (preferred for backend/Kubernetes ecosystem)
• Deep understanding of Kubernetes primitives and controller/reconciler patterns
• Hands-on experience with bare-metal provisioning flows—BMC/Redfish, PXE/iPXE, image management, and hardware inspection
• 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
PREFERRED QUALIFICATIONS:
• Experience building informers or reconciliation bridges that keep external datastores consistent with Kubernetes resource state
• Experience building platforms with strict data and network isolation between tenants
• Familiarity with Terraform/OpenTofu and GitOps-driven configuration (ArgoCD or Flux)
• Familiarity with GPU server hardware, DPUs/NICs, and high-performance datacenter fabrics
