About the role

  • Deploy and configure K3s clusters across heterogeneous hardware (bare metal, ARM/x86 nodes, and accelerators).
  • Manage hybrid, multi-node topologies (single-node edge clusters, dual-node HA, and multi-node deployments).
  • Define and maintain consistent OS images, networking, and storage settings across nodes.
  • Implement GitOps workflows for declarative application management (e.g., ArgoCD, Flux).
  • Define, validate, and manage Kubernetes manifests, Helm charts, and CRDs.
  • Automate lifecycle management of applications and infrastructure through declarative pipelines.
  • Monitor and maintain cluster health, including networking, storage, and node availability.
  • Implement self-healing, scaling, and failover strategies for hybrid deployments.
  • Develop and maintain backup/restore, upgrade, and security hardening processes.
  • Enable interoperability across ARM and x86 nodes in the same deployment.
  • Configure workloads to leverage specialized accelerators (e.g., GPUs, DPUs, FPGAs).
  • Ensure consistent declarative workflows regardless of underlying hardware architecture.
  • Work with DevOps, SRE, and PaaS teams to align K3s cluster deployments with platform goals.
  • Document cluster provisioning, deployment flows, and operational playbooks.
  • Train internal teams on hybrid K3s management and declarative deployment practices.

Requirements

  • Hands-on experience with K3s/Kubernetes deployment and lifecycle management.
  • Strong understanding of multi-node hybrid clusters across x86, ARM, and accelerators.
  • Proficiency with GitOps tools (ArgoCD, Flux) and declarative deployment workflows.
  • Experience with container runtime configuration (containerd, CRI-O, Docker).
  • Familiarity with Linux OS images, networking (CNI), and storage provisioning (CSI).
  • Knowledge of infrastructure-as-code tools (Terraform, Ansible, Helm).
  • Strong debugging skills for cluster bring-up, networking, and workload scheduling.
