Linux Server Systems Engineer Jobs

Linux Server Systems Engineer

Leidos is seeking a Linux Server Systems Engineer to support the National Digital Exploitation & OSINT Center (NDOC). This position requires a technically experienced engineer with expertise in the design, integration, deployment, optimization, and lifecycle support of Linux-based server infrastructure across physical and virtual environments. The Linux Server Systems Engineer will apply systems engineering principles to develop and implement reliable, secure, scalable, and maintainable infrastructure solutions supporting mission-critical customer capabilities.

The engineer will evaluate system requirements, analyze technical issues and performance trends, develop and implement engineering solutions, and identify opportunities to improve system resiliency, automation, security, and operational efficiency. The successful candidate will collaborate with systems engineers, cybersecurity personnel, application teams, infrastructure administrators, and customer stakeholders to translate mission and technical requirements into engineered solutions. Responsibilities include system design and integration, technical analysis, automation, configuration management, performance optimization, system hardening, root cause analysis, testing, and implementation of infrastructure improvements.

This is a 100% on-site position. All work must be performed at the customer site at the Intelligence Community Campus in Bethesda, Maryland.

Primary Responsibilities

• Engineer, integrate, configure, and optimize Linux server solutions across physical and virtual infrastructure environments.
• Perform systems engineering activities including requirements analysis, functional analysis, technical trade studies, interface definition, requirements allocation, integration, system testing, and technical verification.
• Develop technical solutions supporting the implementation, modernization, scalability, reliability, and lifecycle management of enterprise Linux infrastructure.
• Analyze complex system and infrastructure issues, identify root causes, and develop engineering solutions that prevent recurrence and improve system resiliency.
• Evaluate existing infrastructure architecture, configurations, utilization, and performance to identify opportunities for optimization and modernization.
• Design and implement automation for system provisioning, configuration, patching, compliance, monitoring, and lifecycle management using tools such as Ansible, Salt, Puppet, Chef, and scripting languages.
• Engineer and maintain standardized Linux configurations, system baselines, and deployment patterns across RHEL, Rocky Linux, Oracle Linux, Ubuntu, and related platforms.
• Develop and implement Linux system-hardening solutions consistent with customer cybersecurity requirements, security controls, and configuration standards.
• Support technical integration of Linux infrastructure with virtualization, storage, networking, identity, monitoring, backup, security, and application services.
• Conduct performance analysis, capacity assessments, log analysis, and system-level troubleshooting to identify trends and recommend engineering improvements.
• Develop technical solutions for complex infrastructure requirements and evaluate alternative approaches through analysis and trade studies.
• Coordinate with customers, stakeholders, cybersecurity teams, administrators, and other engineering disciplines to collect requirements, analyze technical needs, and implement solutions.
• Develop and execute system integration, verification, validation, and implementation activities for infrastructure changes and new capabilities.
• Support configuration management, change management, technical baseline management, and engineering review activities.
• Perform technical root cause analysis and produce engineering assessments documenting findings, corrective actions, recommendations, and lessons learned.
• Identify and implement opportunities for continuous improvement, automation, standardization, and reduction of manual operational processes.
• Develop and maintain engineering documentation, including system designs, architecture diagrams, technical procedures, configuration standards, implementation plans, test procedures, and operational transition documentation.
• Provide engineering support for mission-critical infrastructure issues and outages, including after-hours support when required.
• Collaborate with 24/7/365 Operations Watch personnel to ensure engineered solutions are effectively transitioned into operations and supported by appropriate technical documentation.

Basic Qualifications

• Bachelor's degree in Systems Engineering, Computer Science, Information Technology, Computer Engineering, or a related technical discipline and 4+ years of relevant experience. Additional years of relevant technical experience may be considered in lieu of a degree.
• Demonstrated experience engineering, deploying, integrating, and maintaining Linux/UNIX server environments.
• Experience with Linux server…
