## Description

**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.

## Requirements

**Required:**

-   Deep technical expertise with Red Hat OpenShift, including extensive experience implementing and operating disconnected/air-gapped OpenShift environments.

-   Strong proficiency with Ansible and Ansible Automation Platform (AAP) for enterprise-scale automation.
-   Strong Linux systems administration experience.
-   Experience with virtualization technologies, including KubeVirt and/or OpenShift Virtualization, and virtual machine lifecycle management.
-   Experience developing or maintaining Infrastructure-as-Code and automated provisioning/configuration workflows.
-   Demonstrated ability to work within secure, offline, classified, or highly regulated computing environments.
-   Strong technical documentation skills with the ability to develop operational procedures and runbooks that can be followed by generalized System Administrators.

**Desired:**

-   Experience integrating and managing GPU/vGPU resources within virtualized or containerized environments.

-   Familiarity with High-Performance Computing (HPC) architectures and resource scheduling concepts.
-   Experience designing VM templates and resource-allocation strategies involving CPU cores, memory, storage, and GPU/vGPU resources.
-   Experience developing self-service or automated VM provisioning workflows.
-   Familiarity with offline content mirroring, disconnected software repositories, and update management.
-   Experience collaborating with security, HPC, infrastructure, and operations teams in classified or DoD-style environments.

**Education:**

-   Bachelor’s degree in Computer Science or a related technical field OR Certified Senior System Administrator (SA) credential required.

**Security Clearance:**

-   Active security clearance required. Requirements to obtain a clearance include US Citizenship, security investigation, etc.
