Company mission
To empower developers and innovators to create extraordinary products and services by automating the discovery, integration, and operation of the best cloud and open-source technologies for their unique needs.
Role
Who you are
- 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
Desirable
- 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 the job involves
- 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 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
- System Reliability: Design the error-handling models, idempotency guarantees, and reconciliation loops necessary to manage long-running provisioning operations reliably
Our take
The global cloud-native applications market has grown rapidly in recent years, as more companies look for scalable and flexible ways to build and run software. Managing these environments - often spread across cloud, on-prem, and hybrid setups - has become increasingly complex. SO that's where Mirantis comes in, focusing on open cloud software and what it calls a ZeroOps approach to simplify operations.
Mirantis offers a range of products used by millions of developers, designed to make it easier to build, deploy, and manage modern applications, Its tools help teams move away for manually handling infrastructure so they can focus more on writing code and delivering new features. As cloud environments continue to evolve, the company is a flexible, open alternative that adapts alongside changing developer needs.
Recently, Mirantis has been pushing further into this space with the development of k0rdent, an open-source platform designed dot act as a "super control plane" for managing Kubernetes across multiple environments. With its latest updates, k0rdent helps teams standardize how they deploy, scale, and monitor applications across cloud, on-prem, and hybrid setups. This focus on simplifying large-scale infrastructure management, combined with an open, community-driven approach, shows Mirantis is doubling down on helping organizations stay flexible while avoiding vendor lock-in.
