Platform Engineer

** Introduction*
* This position is for a Platform Engineer supporting the Army Edge Computing Capability (AECC) project that ALTESS is fielding for the US Army. The AECC solution is a containerized, Kubernetes-based, multitenant hosting environment for hosting Army enterprise and tactical applications. AECC is utilizing Kubernetes and potentially Red Hat Open Shift to implement a cloud-native, software-defined infrastructure across multiple global sites. ALTESS provides value-added common and managed services built on top of the Kubernetes foundation, which hosted Army applications will require.

ALTESS is a managed service provider (MSP) and hosting services provider for Army applications. ALTESS is a Product Lead office under Capability Program Executive (CPE) Enterprise Software and Services (CPE ES2).

** Your role and responsibilities*
* Platform Engineer Duties

* Collaborate with Government engineers to design, develop, and maintain the AECC Kubernetes‑based platform architecture.

* Develop, deploy, and maintain Infrastructure as Code (IaC) to support the deployment, operation, and sustainment of the AECC Kubernetes platform.

* Provision customer name spaces and containerized workloads using IaC as applications are onboarded to the AECC platform.

* Perform day‑to‑day administration of the Kubernetes platform, including patching and upgrading core components such as the control plane, worker nodes, CNI plugins, CSI drivers, and CRI runtimes.

* Configure and manage Container Network Interface (CNI) plugins (e.g., Calico, Cilium, Open Shift SDN) to ensure secure, resilient, and high‑performance networking for Kubernetes workloads.

* Deploy and manage Container Storage Interface (CSI) drivers to enable dynamic provisioning of persistent storage for containerized workloads (e.g., Open Shift Data Foundation, Ceph).

* Monitor platform and cluster resource utilization and proactively notify the AECC Lead when additional capacity or scaling is required.

* Harden the Kubernetes platform in accordance with cloud‑native best practices and applicable government cybersecurity and compliance requirements.

* Troubleshoot platform issues and perform root cause analysis across Kubernetes networking, containerized workloads, persistent storage, and runtime components.

* Develop and maintain platform documentation, including system diagrams, network topology, Kubernetes configurations, CSI and CRI configurations, and standard operating procedures.

* Provide on‑call support for triage and resolution of after‑hours production incidents.

* Recommend and implement improvements to platform security, scalability, reliability, and performance across containerized compute, network, and storage services.

* Build, configure, and administer Kubernetes clusters in support of mission‑critical workloads.

* Implement and manage container registries (e.g., Docker Hub, Harbor, Red Hat Quay) to enable secure container image storage and distribution.

* Deploy and manage persistent storage solutions for containerized workloads (e.g., Open Shift Data Foundation, Ceph, NFS).

** Required technical and professional expertise*
* * Senior‑level experience with Kubernetes‑based platforms, including Red Hat Open Shift, Rancher, or upstream (vanilla) Kubernetes.

* Experience with Container Storage Interface (CSI) drivers for dynamic provisioning of persistent storage (e.g., Open Shift Data Foundation, Ceph, AWS EBS, Azure Disks).

* Strong Infrastructure as Code (IaC) experience using tools such as Helm, Kustomize, and Terraform, with Git Ops workflows using Argo CD or Flux.

* Strong troubleshooting skills across the full technology stack, including Kubernetes networking, storage, servers, and containerized applications.

* Familiarity with persistent storage solutions for Kubernetes workloads (e.g., Open Shift Data Foundation, Ceph, NFS).

* Experience with Kubernetes monitoring and observability tools, such as Prometheus, Grafana, Elasticsearch, Fluentd, and Kibana.

* Security+ or equivalent DoD 8570.01‑M Information Assurance Technical Level II certification.

* Must hold and maintain an active DoD Secret Security Clearance

* Must possess, or obtain within six…
