CAPABILITIES AND EXPERTISE:

• System Administration Red Hat expertise.
• Networking, expertise in configuring and troubleshooting networking setups within HPC clusters, including understanding low-latency interconnects like InfiniBand or Omni-Path.
• Scripting Proficiency, use scripting languages such as Bash, Python, or Perl for automating routine tasks like cluster monitoring, user onboarding, or job submissions.
• Configuration Management, familiarity with tools like Ansible, Puppet, or Chef to automate the deployment and configuration of cluster nodes and services.
• System Monitoring, Implement and manage monitoring tools (e.g., Prometheus, Grafana) to track system health, detect performance bottlenecks, and identify potential hardware or software failures.
• Storage Management, familiarity with large-scale storage systems such as GPFS, Lustre, or NFS, and the ability to troubleshoot file system issues.

• HPC systems are often clusters of interconnected servers. The engineer is responsible for the administration of these clusters, which includes installation, configuration, and maintenance of hardware and software.
• Linux is the dominant OS in HPC environments. The engineer ensures that the OS is updated, secure, and optimized for high-performance workloads.
• HPC environments use job schedulers (e.g., SLURM, PBS, or LSF) to allocate resources efficiently. The engineer manages these schedulers to ensure optimal job performance, queue management, and fair distribution of resources among users.
• Designing and managing backup solutions for large volumes of data, ensuring minimal data loss in case of hardware failures or other disasters.
• Interactions with SMC (Smart Management Center) which is the foundation for hosting infrastructure and application micro-services dedicated in managing a HPC supercomputer.
• Support and maintain technology standards, processes, and policies related to on-prem/cloud Infrastructure in scope.
• Contribute to international projects by providing consultancy regarding HPC infrastructure architectures (on-premises and cloud).
• Suggest system changes in accordance with documented SOPs.
• Produce and maintain appropriate documentation and diagrams describing system setups and overall inventory.
