Full-Stack Software Engineer, Infrastructure (Go) - Remote EU

About the role

Mirantis, a Kubernetes-native AI infrastructure company, is looking for an experienced Full-Stack Software Engineer to design and implement the Infrastructure Services behind its 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. The role is remote within the EU.

Key responsibilities

• Design, build and maintain versioned REST and gRPC APIs for bare-metal server lifecycle, MachineType definitions and cluster CRUD operations.
• Develop asynchronous workflows for server enrollment, inspection, OS provisioning and cluster bring-up, exposing durable status to callers.
• Design error-handling models, idempotency guarantees and reconciliation loops so long-running provisioning operations stay reliable.

Required profile

• Strong experience designing RESTful APIs or gRPC services, including API versioning and gateway patterns.
• Deep understanding of Kubernetes primitives and controller/reconciler patterns, working with systems such as k0rdent, Metal3 and Cluster API.
• Hands-on experience with bare-metal provisioning flows (BMC/Redfish, PXE/iPXE, image management, hardware inspection).
• Experience building workflow-driven or event-driven systems (e.g. Temporal) where operations are long-running and state must stay consistent across retries and failures.

Required skills

• Proficiency in Go (preferred for backend and Kubernetes ecosystems)
• Preferred: informers or reconciliation bridges, multi-tenancy, Terraform/OpenTofu and GitOps (ArgoCD or Flux)
• Preferred: familiarity with GPU server hardware, DPUs/NICs and high-performance datacenter fabrics

What we offer

• Work with an established Silicon Valley leader in cloud infrastructure and with passionate colleagues serving Fortune 500 and Global 2000 customers.
• Cutting-edge open-source work in a young, collaborative company.
• Professional development, training, conferences and working groups.
• Company outings, happy hours, hackathons and tech talks.
• A competitive compensation package with a strong benefits plan.
