Job Description
We are looking for an experienced Full-Stack Software Engineer 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 Machine Type 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, Machine Type 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.
• Full-Stack 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.

• API Development:
  Strong experience designing RESTful APIs or gRPC services. You understand API versioning and gateway patterns.
• Language Stack:
  Proficiency in Go (preferred for backend/Kubernetes ecosystem) and modern Type Script/React (for the Console).
• 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.

• State Reconciliation:
  Experience building informers or reconciliation bridges that keep an external datastore consistent with Kubernetes resource state.
• Multi-Tenancy:
  Experience building…
