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.
