High Performance Computing Systems Administrator

Enable cutting-edge research at the University of Plymouth through reliable, high performance computing.

About the role

The HPC Systems Administrator reports to the Infrastructure Services Team Manager and the University's HPC lead and plays a vital role in managing and enhancing the University’s High Performance Computing environment. Working at the intersection of IT and research, the postholder will ensure the HPC system operates securely and efficiently, empowering researchers to tackle complex computational challenges and drive discovery.

The HPC Systems Administrator will take a leading role in maintaining, optimising, and developing the University’s High Performance Computing (HPC) environment. This position ensures the system remains reliable, secure, and high performing, enabling researchers and academic staff to make the most of advanced computing capabilities.

Key responsibilities and deliverables include:

• System optimisation and performance management – ensure the continued efficiency, scalability, and reliability of the University’s multi-node Linux-based HPC environment through proactive monitoring, tuning, and enhancement.
• Operational management and automation – oversee daily operations, develop scripts and tools to streamline workflows, and introduce automation that improves system reliability and reduces administrative overhead.
• Security and compliance – maintain robust security measures, monitor for vulnerabilities, and ensure compliance with institutional and regulatory requirements for data protection and system integrity.
• User engagement and research support – collaborate with researchers to understand computational requirements, provide expert guidance, and support users in effectively utilising HPC resources.
• Continuous improvement and documentation – maintain detailed documentation, contribute to best-practice standards, and identify opportunities for system enhancement or integration with emerging technologies.

For this role, you will need to be on site 3 days a week. Although we can accommodate working from home for this role, flexibility to be on-site will be expected due to business needs.
