HPC System Engineer

Job Description:

At EDGE bold ideas are engineered into technologies that protect, improve and save lives.

Headquartered in the United Arab Emirates, EDGE is a leading advanced technology group working at the forefront of defence and emerging technologies. Spanning more than 35 specialised companies and multiple centres of excellence, we are purpose-built to move fast. Free from heavy legacy processes, we give our people the autonomy, accountability, and agility to bring breakthrough technologies from concept to reality.

Based in Abu Dhabi, a globally connected hub at the crossroads of Europe, Asia, Africa, and the Middle East, EDGE is home to a truly multicultural community where bold ideas thrive, and the future is shaped.

Together, we are shaping the future.

We are seeking a highly skilled HPC Systems Administrator to manage, optimise, 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.

• Infrastructure Management
• Maintain and administer compute nodes, login nodes, heterogeneous nodes, NAS storage servers, and high‑speed interconnects (Infini Band).
• 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.
• 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.
• 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.
• 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.

• 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.
• 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.
• 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.
• 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.
