CALIBRE is an Employee-Owned AI transformation company delivering mission focused solutions. We are hiring Cloud Platform Engineers to deliver Kubernetes-based platform solutions across commercial and government environments.
This is a hands-on, customer-facing engineering role operating in a professional services model. You will architect, build, harden, and deploy production-ready Kubernetes platforms using Spectro Cloud across SaaS, on-prem, and fully air-gapped environments.
Engagements range from short accelerators to multi-month implementations. Once delivery and knowledge transfer are complete, you move to the next challenge. This is not a long-term operations role.
Openings include:
- TS/SCI
- TS
- Commercial (no clearance required)
What You’ll Do
- 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.
Required Skills
- 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.
Preferred
- 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.
Required Experience
- 3–6 years in cloud, DevOps, or platform engineering.
- Proven experience building and troubleshooting Kubernetes clusters (not only consuming managed services).
What Success Looks Like
- Secure, production-grade clusters delivered on time.
- Customers fully enabled to operate and extend their platform.
- Clear documentation and repeatable architecture patterns.
- High technical credibility in front of senior customer engineers.
- Travel may be required depending on customer engagement and clearance requirements.
