About the job
Saalex is seeking a Computational Systems Engineer (CSE) in China Lake, CA . The selected candidate will be responsible for the architecture, design, initial implementation, automation, and comprehensive documentation of highly customized Red Hat OpenShift environments supporting virtual machines across multiple air-gapped, classified High-Performance Computing (HPC) systems. This position will develop a mature, automated platform that enables System Administrators (SAs) to perform routine operations, maintenance, and VM lifecycle activities without requiring specialized expertise in OpenShift, disconnected environments, or advanced automation. Position Type: Full-Time, Exempt Salary: $135,000-$155,000 Work Location: Onsite – China Lake, CA. This position supports secure, air-gapped, and classified HPC environments.
Essential Functions:
- Architect and design Red Hat OpenShift solutions for air-gapped HPC environments, including offline installation, update strategies, and integration of GPU/vGPU resources for virtual machines.
• Lead the initial implementation and ongoing evolution of OpenShift clusters, Ansible Automation Platform (AAP) workflows, and Infrastructure-as-Code (IaC) solutions. • Develop and refine Ansible playbooks and AAP workflows that automate VM provisioning, configuration, redeployment, and routine administrative activities. • Design automation that abstracts technical complexity and enables generalized System Administrators to reliably perform routine operational tasks. • Develop clear and comprehensive technical documentation, runbooks, and operational guides to support long-term administration and sustainment. • Design VM templates, resource-allocation models, and self-service workflows that maximize utilization of available CPU cores, memory, storage, and vGPU resources. • Establish repeatable and sustainable processes for content mirroring, offline updates, and GPU device management within disconnected environments. • Collaborate with security, HPC, and operations teams during architecture, design, implementation, and transition activities. • Ensure delivered solutions meet applicable classification, security, performance, maintainability, and operational requirements. • Perform other duties as assigned.
