What you'll do
- Administer and maintain the HPC cluster, including compute nodes, storage systems, and networking.
- Evaluate and evolve cluster topology, compute node configuration, and hardware resource utilisation as the estate grows.
- Lead the deployment, configuration, and troubleshooting of HPC tooling, particularly Slurm — including queue structures and job scheduling policies.
- Monitor system performance and ensure high availability of HPC resources, using observability tools such as Prometheus; investigate anomalies and outages.
- Assess and maintain the network file storage solution for throughput, scalability, and latency.
- Maintain, patch, and troubleshoot core Linux infrastructure (RHEL).
- Act as an escalation point for complex technical issues raised by the Riverlane team.
- Provide operational upkeep of core infrastructure, including servers, tooling, and licence managers.
- Maintain Synopsys EDA tooling, including licence server management, environment configuration, and performance optimisation for electronic design automation workflows.
- Provide sound technical support to users of the HPC environment.
- Improve self-service capability for users, enabling routine tasks (e.g. restarting VNC sessions, resetting passwords) to be performed without engineering intervention.
- Automate routine tasks using scripting and infrastructure-as-code tools (Bash, Python, Ansible).
- Collaborate with the Infrastructure Team to plan and implement improvements to HPC infrastructure.
- Own work packages and deliver them within agreed sprint windows.
- Build and maintain documentation for systems, processes, and configurations.
- Communicate effectively with stakeholders on progress and delivered improvements.
- Ensure security and compliance across the HPC estate, including security hardening and lifecycle management.
- Maintain and develop the off-site backup strategy, ensuring data integrity, disaster recovery readiness, and compliance with data retention policies.
What we're looking for
- Extensive experience administering and growing infrastructure in fast-paced engineering environments.
- Enterprise Linux expertise: deep knowledge of Red Hat Enterprise Linux (RHEL) administration, security hardening, lifecycle management, and troubleshooting.
- Hands-on experience configuring, scaling, tuning, and troubleshooting job schedulers (e.g. Slurm) and distributed compute environments.
- Strong understanding of network file storage protocols and network optimisation for computational workloads.
- Proficient with container environments and virtualisation infrastructure.
- High proficiency with infrastructure automation tools (Ansible, Python, Bash) and infrastructure-as-code practices.
- Experience with backup and disaster recovery strategy and implementation.
- Excellent communication skills, with the ability to support both technical and non-technical users and translate complex issues into clear guidance.
Nice to have
- Experience managing licensed EDA or similar specialist software tooling (e.g. Synopsys) is a strong plus.
