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