Job description

We are seeking an Intermediate Kubernetes Platform Engineer to join our platform engineering team and contribute to the delivery of our Edge Kubernetes Platform, which supports both connected and air-gapped environments. In this role, you will work closely with senior engineers to deploy, operate, and optimize Kubernetes-based infrastructure, gaining exposure to advanced topics like GitOps, Rancher Gov stack, and secure workload orchestration.

This is an exciting opportunity for an engineer with solid Kubernetes experience who wants to deepen expertise in platform engineering while working on enterprise-scale, mission-critical systems.

Key Responsibilities

• Assist with deployment and configuration of Kubernetes clusters (upstream, RKE2) in connected and air-gapped environments.
• Support operations of the Rancher Gov stack for multi-cluster management.
• Contribute to GitOps pipelines using Fleet and ArgoCD to enable automation and consistency.
• Help package and distribute workloads using OCI bundles and Helm charts.
• Implement security best practices in collaboration with senior engineers (e.g., network segmentation, access control).
• Participate in cluster upgrades, patching, and monitoring for stability and performance.
• Troubleshoot platform issues and escalate complex problems to senior engineers when needed.
• Document processes, playbooks, and configuration details for repeatability.

Qualifications

• 4–6 years of experience in infrastructure, DevOps, or platform engineering.
• Solid hands-on experience with Kubernetes (preferably upstream or RKE2).
• Working knowledge of Rancher, Helm, and GitOps tools (Fleet, ArgoCD, or similar).
• Familiarity with containerization (Docker), Linux systems, and basic CI/CD practices.
• Good understanding of networking, security basics, and infrastructure operations.
• Strong problem-solving skills and ability to collaborate in cross-functional teams.
• Eagerness to learn advanced Kubernetes practices and grow into senior-level responsibilities.

Nice to Have

• Exposure to edge or air-gapped environments in regulated industries.
• Experience with observability stacks (Prometheus, Grafana, Loki, ELK).
• Familiarity with service meshes such as Istio or Linkerd.
• Contributions to open-source Kubernetes or DevOps projects.
