ABOUT THE ROLE

We are seeking a highly skilled HPC Systems Administrator to manage, optimize, and support our high-performance computing environment used for Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) workloads. This role is responsible for the full lifecycle of HPC operations - from infrastructure and scheduler management to user support, performance optimization, and long-term capacity planning.

The ideal candidate has strong Linux administration experience, deep knowledge of HPC schedulers, and hands-on familiarity with engineering simulation tools.

RESPONSIBILITIES

A. Infrastructure Management

• Maintain and administer compute nodes, login nodes, heterogeneous nodes, NAS storage servers, and high-speed interconnects (InfiniBand).
• Manage and maintain HPC-related databases, ensuring timely backups and audit compliance.
• Monitor hardware health including CPU temperatures, memory errors, and disk failures.
• Ensure high availability, reliability, and minimal downtime across the HPC environment.

B. Scheduler & Resource Management

• Configure and tune job schedulers (Slurm / PBS / LSF / Grid Engine).
• Implement and maintain fair-share scheduling, job priority rules, QoS limits, and preemption policies.
• Manage node reservations for large-scale CFD/FEA workloads.
• Provide best-practice recommendations for CPU/GPU architecture selection for engineering simulations.
• Prevent resource misuse, including node hogging, queue congestion, and starvation of small jobs.

C. User Access, Security & Compliance

• Manage user accounts, permissions, and storage quotas.
• Enforce secure SSH access, MFA, and other security controls.
• Ensure compliance with IT governance, data-security, and audit requirements.
• Apply OS patches, security updates, and vulnerability fixes.

D. Software Stack Management

• Install, update, and manage licenses for engineering solvers such as ANSYS, Siemens, NASTRAN, and others.
• Maintain version control and apply service pack updates as required.
• Manage environment modules (Lmod, Environment Modules).
• Optimize compilers, MPI libraries, math libraries, and GPU/graphics-intensive drivers for performance.

RESTRICTED

E. Performance Monitoring & Optimization

• Monitor node utilization, queue wait times, job failures, and overall cluster performance.
• Identify and resolve network congestion, I/O bottlenecks, and memory pressure issues.
• Conduct performance tuning and benchmarking for CFD/FEA workloads.
• Recommend improvements to enhance throughput and efficiency.

F. Troubleshooting & User Support

• Diagnose and resolve job crashes, memory leaks, solver errors, and environment issues.
• Assist users with HPC batch scripting and job optimization.
• Provide training sessions and best-practice guidance for HPC users.
• Maintain documentation, onboarding guides, and knowledge-base resources.

G. Storage & Data Lifecycle Management

• Enforce storage quotas, purge policies, and data-retention rules.
• Manage backup, archival systems, and RAID configurations.
• Ensure smooth operation of parallel file systems (Lustre, GPFS, BeeGFS).
• Support efficient data workflows for large CFD/FEA datasets.

H. Capacity Planning & Future Growth

• Plan for future expansion including increased core counts, GPU adoption, memory-heavy nodes, and faster interconnects.
• Evaluate new hardware technologies and benchmark workloads before procurement.
• Provide input into long-term HPC strategy and infrastructure roadmap.

BASIC QUALIFICATIONS

• Bachelor’s or Master’s degree in Computer Science, Engineering, Physics, or related field.
  • 3-7 years of experience administering Linux-based HPC clusters.
  • Strong knowledge of HPC schedulers (Slurm/PBS/LSF).
  • Experience with MPI, OpenMP, and distributed computing.
  • Familiarity with CFD/FEA solvers and engineering workflows.
  • Proficiency in scripting (Bash, Python).
  • Experience with high-speed networking and parallel file systems.

  PREFERRED QUALIFICATIONS

  • Experience with GPU-accelerated workloads and CUDA-enabled solvers.
  • Knowledge of container technologies (Singularity/Apptainer).
  • Experience with monitoring tools (Grafana, Prometheus, XDMoD).
  • Background supporting engineering or scientific computing environments.

  • Understanding of performance profiling and benchmarking.
