About the role
Senior Linux Administrator
Location: Chandler, AZ
Schedule: Hybrid, 3-4 days onsite per week
Salary: $90,000-$120,000 base + benefits and additional compensation
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 and system 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 Linux server and workstation 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 using EDA tools and running compute-intensive design and simulation workloads.
- Monitor Linux jobs processes/operations 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, and other repetitive tasks.
- 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.
Required Qualifications
- 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.
- Experience supporting Linux systems connected to NFS, NAS, or shared enterprise storage.
- Scripting and automation experience using Bash, Python, Perl, or similar technologies.
- Deep knowledge of Linux security, hardening, patch management, and vulnerability remediation.
- Ability to support technical engineering users and troubleshoot beyond the operating-system layer.
- Hands on development and Linux support, Proactive, ownership-oriented approach to infrastructure.
- Knowledge of Netapp, IBM Spectrum LSF and familiarity with Cadence EDA tools is highly desirable.
Preferred Experience
- Semiconductor, aerospace, defense, electronics, or 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, CF Engine or similar Linux automation/configuration-management tools.
- Experience supporting specialized engineering or design applications.
Who Will Succeed in This Role?
We're 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.
