Mid-Level or Senior Linux System Admin

Kforce has a client that is seeking a Mid-Level or Senior Linux Administrator in Chandler, AZ. The schedule is hybrid, 3-4 days onsite per week.

About the Opportunity:

We are seeking an experienced Senior Linux Administrator to join a lean IT team supporting a highly technical, compute-intensive engineering environment. This is not a traditional Linux administration role focused solely on server maintenance and closing tickets. We are looking for someone who takes ownership of their environment, investigates root causes, monitors performance and capacity, automates repetitive work, and recommends improvements to keep critical engineering workloads running efficiently.

The successful candidate will serve as a Linux subject matter expert and work closely with engineering and design teams. Semiconductor industry experience is preferred, but candidates from aerospace, defense, electronics, or other engineering-intensive environments are strongly encouraged to apply.

Responsibilities:

• Administer and support enterprise RHEL/Rocky Linux server environments
• Own Linux system performance, reliability, security, patching, and continuous improvement
• Monitor CPU, memory, storage, and workloads and perform capacity planning to anticipate future infrastructure needs
• Perform root-cause analysis for complex Linux and infrastructure issues
• Support engineers running compute-intensive design and simulation workloads
• Monitor Linux jobs/processes and troubleshoot workload performance issues
• Support Linux connectivity to NFS/NAS enterprise storage, including performance, latency, permissions, and I/O troubleshooting
• Develop Bash, Python, Perl, or similar scripts to automate administration, monitoring, health checks
• Maintain Linux systems in accordance with cybersecurity and DoD-related security requirements
• Collaborate across engineering, storage, networking, security, and application teams to resolve infrastructure issues
• 5+ years of hands-on Linux systems administration experience
• Strong experience with RHEL, Rocky Linux, CentOS, or similar enterprise Linux distributions
• Strong Linux troubleshooting, performance monitoring, patching, process management, and system administration skills
• Understanding of server infrastructure, including CPU, memory, storage, networking, and capacity planning
• Scripting and automation experience using Bash, Python, Perl, or similar technologies
• Understanding of Linux security, hardening, patch management, and vulnerability remediation
• Ability to support technical engineering users and troubleshoot beyond the operating-system layer
• Proactive, ownership-oriented approach to infrastructure

Preferred Skills:

• Medical Device or Semiconductor or aerospace, defense or consumer electronics, or other engineering-intensive environments
• Supporting Linux infrastructure used by engineering or design teams
• High-compute or HPC-style Linux environments
• NetApp/ONTAP or similar enterprise storage
• IBM Spectrum LSF, Slurm, or another workload/job scheduler
• DoD-regulated environments and exposure to NIST SP 800-171, CMMC, DISA STIG, or FIPS requirements
• Ansible or similar Linux automation/configuration-management tools
• Experience supporting specialized engineering or design applications

Who Will Succeed in This Role:

We are looking for the Linux Administrator who doesn't just close the ticket but wants to understand why the problem happened in the first place. If an engineering workload suddenly slows down, your instinct is to investigate CPU and memory usage, storage I/O, network performance, running processes, capacity, and the workload itself to identify the root cause. This is an opportunity to become the Linux expert on a lean team, take meaningful ownership of an engineering-critical environment, and expand your experience across automation, security, storage, workload management, and capacity planning.

The pay range is the lowest to highest compensation we reasonably in good faith believe we would pay at posting for this role. We may ultimately pay more or less than this range. Employee pay is based on factors like relevant education, qualifications, certifications, experience, skills, seniority, location, performance, union contract and business needs. This range may be modified in the future.

We offer comprehensive benefits including medical/dental/vision insurance, HSA, FSA, 401(k), and life, disability & ADD insurance to eligible employees. Salaried personnel receive paid time off. Hourly employees are not eligible for paid time off unless required by law. Hourly employees on a Service Contract Act project are eligible for paid sick leave.
