The Senior LINUX SysAdmin will build, optimize, and maintain the underlying infrastructure required to test the team’s modern software applications in a highly secure, offline environment. Working alongside the Senior Software Engineers and DevOps teams, the candidate will ensure servers hosting environments and CI/CD tools are stable, secure, and dynamically scaled. Focus on automating server deployment, enforcing DoD STIG compliance on RedHat systems, and optimizing the environment to seamlessly bring servers up or down based on testing needs of Java Spring Boot applications and microservices architecture. RESPONSIBILITIES Deploy, configure, and dynamically scale infrastructure across bare metal servers and virtual machines based on the fluctuating testing demands of the Java Spring Boot applications. Maintain, monitor, and optimize the underlying server infrastructure that hosts CI/CD tools (including GitLab and Jenkins), ensuring high availability for DevOps teams managing pipelines. Implement and heavily automate configuration, STIG compliance enforcement, and routine patching of RedHat Linux8/9 systems to ensure maximum security and minimal manual overhead.

At least five (5) years of experience, including extensive hands‑on administrative experience with RedHat Linux8/9 deployment, automated patching, and STIG application. Strong scripting and infrastructure automation capabilities (using tools such as Bash, Python, or Ansible) to transition manual tasks into automated provisioning and dynamic scaling workflows. Proven hands‑on experience deploying, configuring, and administering bare metal server hardware and virtual machines to support high‑demand testing environments and microservices architectures. Demonstrated ability to maintain and optimize underlying server hardware and operating systems that support enterprise CI/CD platforms like GitLab and Jenkins. DESIRED QUALIFICATIONS Fully adjudicated DoD active Secret clearance. Experience with deployment, configuration, and daily usage of RedHat Satellite for centralized patch management and RedHat Identity Management (IdM) servers for authentication. Familiarity with containerization and orchestration technologies, with ability to evaluate and introduce Kubernetes in the future. Solid understanding of system resource management and how dynamic infrastructure scaling impacts performance and testing of enterprise‑level Java Spring Boot applications. Prior experience executing administrative duties and secure physical data transfers (sneakernet) in fully disconnected or highly classified environments. Relevant industry certifications such as RedHat Certified System Administrator (RHCSA) or RedHat Certified Engineer (RHCE).
