Responsibilities:

System Administration & Maintenance:Install, configure, and maintain HPC clusters (hardware, software, operating systems), perform regular updates/patching, manage user accounts and permissions, and troubleshoot/resolve hardware or software issues.

Performance & Optimization:Monitor and analyse system and application performance, identify bottlenecks, implement tuning solutions, and profile workloads to improve efficiency.

Cluster & Resource Management:Manage and optimize job scheduling, resource allocation, and cluster operations using tools such as Slurm, LSF, Bright Cluster Manager / Base Command Manager, OpenHPC, and Warewulf.

Networking & Interconnects:Configure, manage, and tune Linux networking (TCP/IP, DNS, routing) and high-speed HPC interconnects (InfiniBand, Ethernet) to ensure low-latency, high-bandwidth communication.

Storage & Data Management:Implement and maintain large-scale storage and parallel file systems (Lustre, Ceph, GPFS), ensure data integrity, manage backups, and support disaster recovery.

Security & Authentication:Implement security controls, ensure compliance with policies, and manage authentication and directory services such as LDAP and Active Directory.

DevOps & Automation:Use configuration management and DevOps practices (Ansible, Terraform, Jenkins, Git) to automate deployments, application packaging (RPM/DEB), and system configurations.

User Support & Collaboration:Provide technical support, documentation, and training to researchers; collaborate with scientists, HPC architects, and engineers to align infrastructure with research needs.

Planning & Innovation:Contribute to the design and planning of HPC infrastructure upgrades, evaluate and recommend hardware/software solutions, and explore cloud-based HPC solutions where applicable.

Qualifications:

  • Bachelor’s degree in Computer Science, Engineering, or a related field (equivalent experience may substitute for degree).
  • Minimum of 10 years of systems experience, including at least 5 years working specifically with HPC.
  • Strong knowledge of Linux operating systems (e.g., Rocky Linux, Ubuntu) with a fundamental understanding of Linux internals, system administration, and performance tuning.
  • Experience building and managing RPM and DEB packages.
  • Experience with cluster management tools such as Bright Cluster Manager, OpenHPC stack, or Warewulf.
  • Proficiency with job schedulers and resource managers such as Slurm and LSF.
  • Strong understanding of Linux networking (e.g., TCP/IP, DNS, routing) and HPC interconnects (e.g., InfiniBand, Ethernet) including performance tuning.
  • Knowledge of parallel file systems such as Lustre, Ceph, or GPFS.
  • Working knowledge of Linux authentication and directory services such as LDAP and Active Directory.
  • Proficiency in scripting languages (e.g., Python, Bash, R) and familiarity with MPI libraries for parallel and distributed computing (nice to have).
  • Strong experience with DevOps and configuration management tools, including Ansible, Terraform, Jenkins, and Git.
  • Knowledge of HPC in cloud environments (e.g., AWS, Azure, GCP HPC offerings) is a plus.
  • Strong knowledge of Linux security, compliance standards, and data protection best practices.
  • Excellent communication, interpersonal, and problem-solving skills.
