    Terms of Employment

    • Full-Time, Permanent
    • This position is onsite four days per week in Ft. Washington, MD. Once every two-to-three weeks, there is one day of work onsite in Warrenton, VA. The ability to work remotely once per week is acceptable.

    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. This role requires more than standard administration; we are looking for a specialist with CLI-level mastery capable of deep-tier kernel tuning and performance optimization. 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.
    • Cameo & VDI Administration
    • 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.

    Preferred Skills & Experience

    Active Top Secret/SCI clearance.

    Red Hat Certified System Administrator (RHCSA) or Engineer (RHCE).

    Experience with cloud-based Linux deployments.

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