• Ability to work all shifts, including Owl shift (12am – 8am), weekends, and holidays.

Additional qualifications at the SES.2 level

• Comprehensive knowledge of HPC environments and technologies, such as Linux clusters, InfiniBand, Slurm, Lustre, and archival storage systems.
• Proficient experience developing software tools and automation in C/C++, Python, or similar languages, and broad application of technical principles to resolve moderately complex system, network, and facility issues.
• Experience leading technical work packages or discrete projects and mentoring less-experienced staff, and ability to work with limited direction in a dynamic environment with competing priorities.
• Relevant previous experience and demonstrated ability to perform independent technical work.

Qualifications We Desire

• Experience with monitoring and observability tools, such as Grafana, Prometheus, Splunk, or Nagios.
• Experience with data center utility infrastructure and building management systems, including power distribution, water distribution, and cooling distribution units supporting HPC environments.
• Experience with virtual machines, container technologies, and orchestration, such as Docker, Podman, or Kubernetes.
• Experience working in a Closed Area or other secure computing environment.
