• Strong proficiency with Linux system administration (preferably RHEL or derivatives).
• Strong proficiency troubleshooting and diagnosing OS-level impacts on system performance and stability.
• Proficiency with CI/CD platforms, build automation tools, and version control systems (Bamboo, Perforce, GitHub Actions, git).
• Proficiency with shell scripting and higher-level scripting languages (Python and Bash preferred).
• Familiarity with virtualization technologies and containerization (VMware, Docker).
• Familiarity with C++ build environments and tooling (CMake, compilers, linkers).
• Knowledge of networking fundamentals and security practices in Linux environments.
• Comfortable collaborating across engineering teams and communicating clearly about system-level issues.
• Strong analysis and problem-solving skills.
• Can work independently and manage priorities with only general technical direction.

Nice To Haves

• Experience customizing and maintaining Linux kernels or distributions.
• Experience maintaining Linux distributions targeted for specialized workloads.
• Experience with OS monitoring and logging tools.

• Update OS components to maintain compatibility, stability, and security across multiple deployed systems.
• Standardize processes, practices, and configurations for security compliance and modern best practices.
• Stay current with Linux security patches and compliance requirements.
• Support and maintain existing CI/CD pipelines and build environments for multiple teams and products.
• Develop and manage build scripts and tooling (CMake, Docker, Python) to streamline builds and deployments.
• Diagnose networking and network traffic related system issues.
• Manage current automations and develop additional solutions to increase automation.
• Configure and manage virtualized environments for development, testing, and deployment.
• Design, integrate, and test flight simulator architectures, specifically the operating systems, networks, and interfaces that comprise those systems.
• Coordinate with multiple teams and products to test, debug, and optimize the fully delivered training solution.
• Provide the OS and tools necessary for the application teams and assist and advise those teams on OS related issues.
• Assist with debugging application issues that may be caused by system-level interactions.
