Overview & Responsibilities

  • As a Senior Linux Systems Engineer, you will serve as the technical authority for a Red Hat Enterprise Linux (RHEL) environment supporting the Cameo (Dassault Systmes/No Magic) suite.

You will ensure the integrity of server resources, manage a complex Virtual Desktop Infrastructure (VDI), and provide high-level technical support to a large community of system engineers and partners.


You will be responsible for

  • Advanced Systems Engineering & Kernel Optimization
  • Perform kernel-level tuning (sysctl), I/O scheduling, and memory management to optimize RHEL for high-demand MBSE workloads.
  • Execute all administrative tasks, file management, and system troubleshooting via the command-line interface (CLI) in a headless or cloud environment.
  • Proactively monitor system health and performance to ensure 99.9% availability of mission-critical server resources and hardware.

  • Act as the primary administrator for Cameo Systems Modeler and Teamwork Cloud, managing user groups, permissions, and server-side configurations.
  • Configure and troubleshoot user profiles in a virtual desktop environment using XRDP.
  • Create, maintain, and deploy virtual desktop images, ensuring optimized disk storage and session management for multiple concurrent users.
  • Security, Automation & Compliance
  • Work closely with ISSO/ISSE teams to ensure systems meet ATO/accreditation standards through aggressive scanning, patching, and STIG compliance.
  • Utilize Ansible, Puppet, or scripting (Bash/Python) to automate routine maintenance and configuration management.
  • Author and maintain technical standards, Standard Operating Procedures (SOPs), and "RunBooks" to ensure continuity of operations.
  • Agile Integration & Collaboration
  • Maintain a detailed work backlog in JIRA, participating in Agile ceremonies and communicating technical status to PMs and Government leads.
  • Explain complex technical considerations to external partners and provide high-tier technical support to the user community.


Required Skills & Experience

  • Active Top Secret clearance with SCI eligibility.
  • IAT Level II compliant (e.g., Security+, CySA+, GSEC, SSCP, CCNA Security, CND, GICSP).
  • Expert-level knowledge of Red Hat Enterprise Linux (RHEL).
  • Expert-level proficiency in the Linux Command Line Interface (CLI). Must be able to manage the full OS lifecycle without a Graphical User Interface (GUI).
  • Demonstrated experience in Linux kernel tuning and performance optimization for enterprise-scale applications.
  • Proven experience with XRDP, VDI session management, and image deployment.
  • Proficiency in Cameo / No Magic software.
  • Experience using JIRA.
  • Proficiency in Bash or Python scripting and Ansible configuration management.
  • Solid understanding of TCP/IP, SSH, and secure networking protocols.

Experience with cloud-based Linux deployments.

Background in Model-Based Systems Engineering (MBSE) workflows.
