Overview & Responsibilities
We are seeking a high-level Linux Systems Subject Matter Expert to provide technical leadership and advanced engineering support for mission-critical environments. This role is not merely about maintenance; it requires a deep-tier specialist capable of kernel-level tuning, performance optimization, and the integration of Dassault Systmes Cameo (No Magic) suite within a secure, multi-site architecture. The successful candidate will be the primary technical authority for Linux-based infrastructure, ensuring high availability and peak performance for complex modeling and simulation workflows. You will
Perform deep-dive troubleshooting and performance optimization using CLI-level mastery. This includes kernel parameter tuning, memory management optimization, and I/O scheduling to support data-intensive MBSE tools.
Support and optimize the Cameo Systems Modeler (and associated No Magic products) environment. This includes managing Teamwork Cloud (TWCloud) deployments, coordinating updates, and ensuring seamless integration with underlying Linux distributions.
Develop sophisticated scripts (Bash, Python, or Ansible) to automate repetitive tasks, hardening procedures, and environment provisioning.
Maintain rigorous security standards in accordance with TS/SCI protocols. Apply STIGs (Security Technical Implementation Guides) and manage RMF (Risk Management Framework) requirements without compromising the performance of the Cameo environment.
Act as the technical bridge between the Ft. Washington and Warrenton facilities, ensuring configuration parity and reliable data synchronization across geographically dispersed nodes.
Required Skills & Qualifications
Expert-Level Linux Administration
Extensive experience in a "headless" environment. You should be comfortable navigating complex filesystems, managing processes, and debugging network stacks exclusively via the command line.
Proven ability to modify kernel parameters (sysctl), manage modules, and optimize the OS for specific application workloads (e.g., database performance for TWCloud).
Expertise in LVM, NFS, and encrypted storage solutions (LUKS) within a Linux context.
Dassault Systmes / Cameo Experience
Hands-on experience with Cameo Systems Modeler, Teamwork Cloud, and Cameo Collaborator.
Knowledge of the Java Virtual Machine (JVM) tuning required to keep Cameo/MagicDraw running efficiently under heavy model loads.
Understanding of the licensing servers (FlexNet/FlexLM) associated with Dassault products.
Security & Clearance
Must possess an active Top Secret clearance with SCI eligibility (Active TS/SCI is highly preferred).
Preferred Qualifications
Experience with RHEL/CentOS or Rocky Linux in a secure government environment.
Background in Model-Based Systems Engineering (MBSE) workflows.
Experience with containerization (Docker/Podman) or orchestration (Kubernetes) for deploying No Magic services.
