We are seeking a highly skilled High-Performance Computing (HPC) Administrator to design, deploy, maintain, and optimize large-scale compute clusters which could be used for advanced scientific, engineering and AI workloads.

You will be responsible for managing high-density compute nodes, InfiniBand interconnects, job scheduling environments, ensuring high availability, scalability, and efficiency across the cluster ecosystem.

Key Responsibilities

Linux Skills

Familiarity with one, or more, shell environments (BASH, sh, tcsh, ksh, etc.)

Experience administering Linux (boot process, file systems, kernel modules)

Familiarity with core OS services such as: SSH, telnet, FTP, NFS, DNS, DHCP, Samba, LDAP

Familiarity with networking tools (ping, tracert, tracemon, tcpdump, etc.)

Understanding of the OSI model and related concepts

Cluster Administration

Install, configure, and maintain Linux-based compute and login nodes.

Manage workload schedulers (e.g., Slurm, PBS Pro) and optimize job throughput and queue performance.

Oversee software provisioning, OS image deployment, and firmware updates across thousands of nodes.

Manage HPC management frameworks such as HPE Performance Cluster Manager (HPCM), Bright Cluster Manager, or equivalent.

Networking & Interconnect





Monitor and tune high-speed fabrics such as InfiniBand (HDR/NDR) including subnet managers (UFM, OpenSM) and link diagnostics.

Need to ensure low latency, congestion-free data paths across compute and storage.

Monitoring & Automation

Implement comprehensive cluster monitoring using tools like Grafana, Prometheus, Nagios or Opsramp.

Develop automation and orchestration scripts (Bash, Python, Ansible) for provisioning, health checks, and performance tuning.

Proactively identify performance bottlenecks and propose corrective actions.

Security & Compliance

Maintain secure authentication, role-based access, and audit controls across nodes.

Apply patches, enforce configuration management, and ensure compliance with organizational IT policies.

Qualifications

Essential

Bachelor’s degree in Computer Science, Engineering or a related technical field.

Strong experience in Linux systems administration (RHEL/SLES/Ubuntu) in an HPC or data center workplace.

Minimum 5 years of experience in HPC administration is valuable.

Hands-on expertise with Slurm, PBS Pro job schedulers.

Familiarity with InfiniBand networking

Proficiency in scripting (Bash, Python, or Ansible) and version control (Git).
