Responsibilities

Qualifications:

API Design: design, build, and maintain versioned REST and gRPC APIs for bare-metal server lifecycle, MachineType definitions, and cluster CRUD operations.
Provisioning & Workflows: develop asynchronous workflows that drive server enrollment, OS provisioning, and cluster bring-up, exposing durable status to callers.
Full-Stack & UI: implement and maintain consoles and interfaces that visualize hardware inventory, provisioning progress, and cluster health.
Reliability: design error-handling models, idempotency guarantees, and reconciliation loops for long-running provisioning operations.
API Development: strong experience designing RESTful APIs or gRPC services with API versioning and gateway patterns.
Language Stack: proficiency in Go (backend/Kubernetes) and modern TypeScript/React (for the Console).
Kubernetes: deep understanding of Kubernetes primitives and controller/reconciler patterns; experience with systems like k0rdent, Metal3, and Cluster API.
Bare-Metal Provisioning: hands-on experience with BMC/Redfish, PXE/iPXE, image management, and hardware inspection.
