About this role
CALIBRE Systems, Inc. is seeking Cloud Platform Engineers to deliver Kubernetes-based platform solutions across commercial and government environments. This hands-on, customer-facing engineering role involves architecting, building, hardening, and deploying production-ready Kubernetes platforms using Spectro Cloud across various environments.
Responsibilities:
- Architect and deploy Kubernetes platforms using Spectro Cloud in:
- VMware vSphere
- Bare metal
- AWS, Azure, GCP
- Restricted / air-gapped networks
- Build and configure clusters from scratch, including control plane, networking, storage, and ingress
- Integrate CI/CD pipelines and container supply chains (build, scan, push, deploy)
- Containerize and modernize customer workloads using Helm, OCI registries, and Git-based workflows
- Troubleshoot real-world distributed system issues across:
- CNI and DNS
- Load balancers and ingress
- TLS/certificates
- Persistent storage and CSI drivers
- Support both connected SaaS-style deployments and fully offline artifact mirroring environments
- Produce clear architecture diagrams, runbooks, and structured knowledge transfer for customer independence
Requirements:
- Control plane components
- Networking (CNI, DNS, ingress, load balancers)
- RBAC and security boundaries
- Persistent storage (PV/PVC, CSI)
- Experience with AWS, Azure, or GCP (EKS/AKS/GKE)
- Experience implementing CI/CD pipelines (GitLab, GitHub Actions, Azure DevOps, etc.)
- Hands-on experience with Docker/OCI images and private registries
- Experience working in restricted or air-gapped environments
- Strong troubleshooting skills and ability to operate independently in customer-facing scenarios
- 3–6 years in cloud, DevOps, or platform engineering
- Proven experience building and troubleshooting Kubernetes clusters (not only consuming managed services)
- Experience with cluster lifecycle platforms (Spectro Cloud, Rancher, OpenShift, Tanzu)
- Helm chart authoring and Kubernetes operator familiarity (CRDs/CRs)
- Experience with artifact mirroring, offline deployments, and secure supply chains
- Exposure to STIG hardening, vulnerability management, and compliance-driven environments
- CKA, CKAD, or cloud provider certifications
