Essential experience:

You’ll ideally have:

• Several years’ experience supporting Linux infrastructure in compute-intensive or highly available environments
• Practical exposure to HPC platforms, including workload schedulers and distributed systems
• Strong knowledge of Red Hat–derived operating systems
• A proven track record of automating operational tasks using scripting or infrastructure-as-code tools
• A solid understanding of networking concepts as they apply to server and cluster environments
• Experience implementing or maintaining backup, recovery, and data protection solutions
• The confidence to communicate clearly with both technical and non-technical stakeholders
