Key Responsibilities
HPC Cluster Management & Optimization
• Design, implement, and maintain HPC environments, including compute, storage, and network components.
• Configure and optimize Slurm, PBS Pro, or other workload managers/schedulers for effective job scheduling and resource allocation.
• Implement performance tuning for CPU, GPU, memory, I/O, and network subsystems to meet workload demands.
• Manage HPC filesystem solutions such as Lustre, BeeGFS, or GPFS/Spectrum Scale. Linux Administration
• Administer enterprise-grade Linux distributions (RHEL, CentOS, Rocky, Ubuntu) in large-scale compute environments.
• Manage kernel upgrades, patching, and security hardening.
• Troubleshoot kernel-level and system-level issues for performance and stability. Automation & Configuration Management
• Develop and maintain Ansible playbooks/roles for automated provisioning, configuration, and patching of HPC systems.
• Integrate Ansible with CI/CD pipelines for infrastructure as code (IaC) practices.
• Automate cluster deployment and environment consistency across hundreds of nodes. Monitoring, Troubleshooting & Support
• Implement and maintain monitoring tools (e.g., Grafana, Prometheus, Nagios, Ganglia).




• Troubleshoot complex HPC workloads, MPI communication issues, and application performance bottlenecks.
• Provide Tier-3 escalation support for Linux/HPC-related incidents. Collaboration & Documentation
• Work closely with research teams, DevOps engineers, and system architects to deliver high-performance solutions.
• Document architecture, SOPs, troubleshooting guides, and performance tuning methodologies. Requirements Required Skills & Experience
• 8–10 years of hands-on Linux system administration experience in production environments.
• 5+ years managing HPC clusters at scale (500+ cores / multiple petabytes of storage).
• Strong Ansible automation skills (complex playbooks, roles, variables, templates).
• Deep understanding of MPI, OpenMP, and GPU/accelerator integration in HPC workloads.
• Proficient with HPC job schedulers (Slurm, PBS Pro, LSF).
• Experience with HPC storage (Lustre, BeeGFS, GPFS).
• Strong knowledge of TCP/IP networking, Infiniband, and RDMA technologies.
• Experience with performance tuning and benchmarking tools (perf, hpc tool kit, Intel VTune, Iperf, fio).
• Scripting proficiency in Bash, Python, or Perl for automation and tooling. Preferred Qualifications
• Experience with containerized HPC (Singularity, Apptainer, or Podman).
• Familiarity with cloud-HPC integration (AWS Parallel Cluster, Azure Cycle Cloud, GCP HPC).
• Knowledge of security compliance standards (CIS benchmarks, STIG).
• Contribution to HPC community tools or open-source projects. Soft Skills
• Strong problem-solving and analytical thinking.
• Ability to mentor junior engineers and collaborate across teams.
• Excellent communication skills for technical and non-technical stakeholders.
