Job summary

Mirantis is seeking a backend engineer to design and maintain infrastructure APIs for the bare-metal server lifecycle, MachineType definitions, and cluster CRUD operations. You will build versioned REST and gRPC interfaces and own provisioning workflows.

You will implement consoles to visualize hardware inventory, provisioning progress, and cluster health, and contribute to reliability through robust error handling, idempotency, and long-running operation management.

Qualifications

• Strong experience designing RESTful APIs or gRPC services, including API versioning and gateway patterns.
• Proficiency in Go for backend/Kubernetes ecosystem.
• Kubernetes primitives and controller/reconciler patterns, interfacing with systems like k0rdent, Metal3, and Cluster API.
• Bare-metal provisioning workflows, including BMC/Redfish, PXE/iPXE, image management, and hardware inspection.
• Experience building asynchronous or event-driven workflows (Temporal) with long-running operations and retry/failure handling.

Responsibilities

• Design, build, and maintain versioned REST and gRPC APIs for bare-metal server lifecycle, MachineType definitions, and cluster CRUD.
• Develop asynchronous workflows driving server enrollment, inspection, OS provisioning, and cluster bring-up with durable status exposed to callers.
• Implement and maintain consoles visualizing hardware inventory, provisioning progress, and cluster health.
• Design error-handling models, idempotency guarantees, and reconciliation loops for reliable long-running provisioning.

Job description

Key Responsibilities

• 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.

Qualifications

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

Preferred Qualifications

• 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.

What does Mirantis offer you?

• Work with an established Silicon Valley leader in the cloud infrastructure industry;
• Work with exceptionally passionate, talented and engaging colleagues, helping Fortune 500 and Global 2000 customers implement next-generation cloud technologies;
• Be a part of cutting-edge, open-source innovation;
• Thrive in the high-energy environment of a young company where openness, collaboration, risk-taking, and continuous growth are valued;
• Professional development and training;
• Attend conferences and working groups;
• Company outings, happy hours, hackathons, and tech talks;
• Receive a competitive compensation package with a strong benefits plan.
