What does a Senior Linux Systems Engineer do?

A Senior Linux Systems Engineer is responsible for designing, implementing, and maintaining complex Linux-based systems and servers within an organization. Their duties often include configuring system architecture, ensuring system security and reliability, automating processes with scripting, and troubleshooting advanced issues. They may also mentor junior engineers, manage large-scale deployments, and contribute to planning the IT infrastructure. This role requires deep expertise in Linux operating systems, networking, and system optimization.

How does a Senior Linux Systems Engineer typically collaborate with development and security teams?

A Senior Linux Systems Engineer often works closely with development teams to ensure that infrastructure is tailored to the needs of applications, facilitating smooth deployments and resolving compatibility issues. Collaboration with security teams is also essential, as they help implement and maintain system hardening, intrusion detection, and compliance with security policies. Regular meetings, ticketing systems, and cross-functional project planning are common ways these teams work together to ensure system reliability, security, and performance.

When we build our customer's environments, our team collaborates to design, implement, and maintain the systems from inception to retirement.
Major Duties/Responsibilities:
  • Advocate and promote HPC and clustered computing services to researchers who process large data sets and/or develop code as a part of their project.
  • Ensure the availability, performance, scalability, and security of production systems.
  • Leverage automation and monitoring solutions that minimize our day-to-day maintenance and scout opportunities to optimize system management practices or system performance.

Preferred Qualifications:
  • Active DOE Q, active DOD Top Secret, or active DOD TS/SCI clearance is heavily preferred for consideration.
  • Solid understanding of multiple operating systems and cluster technologies.
  • Experience performing advanced troubleshooting and system administration with Linux Servers.
  • A strong desire to innovate and identify new technologies and opportunities and be able to communicate the potential benefits of those choices to others within the team and our research partners.
  • A collaborative and upbeat approach to thrive on the opportunity to build trust and credibility and ultimately become a trusted advisor to our research teams.
  • Experience with Rocky/Centos/RHEL, Ubuntu, VMware.
  • Understanding of HPC platforms to support users with SLURM job submissions and troubleshooting.
  • Experience building and running containerized applications in an HPC environment.
  • Experience with multiple deployment mechanisms like Diskless, Warewulf, and traditional deployment (cobbler, PXEboot, and/or Bright).
  • Experience managing systems utilizing GPU (NVIDIA and AMD) clusters for AI/ML and/or image processing.
  • Knowledge of networking fundamentals including TCP/IP, traffic analysis, common protocols, and network diagnostics.
  • Experience with Infiniband networks and diagnostics.
  • Experience with performance and diagnostic tools for benchmarking, analysis and tuning of systems, networking, and storage.
  • Experience with Grafana, CheckMK, Nagios, Zabbix, SolarWinds, Ganglia, or other network and device monitoring systems.
