Senior Technical Support Engineer – Slurm

Jobtailor; Deutschland; Remote; EUR 70.000 - 100.000; Vollzeit

Zusammenfassung

Jobtailor is seeking a senior Slurm Administrator to own production AI and HPC clusters in a German-based environment. You will diagnose complex issues, optimize configurations, and guide customers to reliable recoveries.

Collaborating with engineering, you will create reproducible test cases, diagnostic tools, and training materials to strengthen Slurm expertise across the organization. This role emphasizes strong Linux administration and multitier problem solving.

Qualifikationen

• 5+ years of hands-on experience administering and supporting Slurm in production HPC or AI environments.
• Expert-level understanding of Slurm architecture, daemons, configuration, scheduling behavior, accounting, resource management, and failure modes
• In-depth Linux system-administration and troubleshooting experience, including systemd, cgroups, authentication, networking, and database-backed services
• Experience operating Slurm across multi-user clusters with complex scheduling policies and heterogeneous compute resources
• Familiarity with Slurm source code, plugins, SPANK, Lua job-submit plugins, or upstream issue investigation
• Experience with containers and HPC integration technologies such as Pyxis, Enroot, Apptainer, or Singularity
• Previous experience integrating Slurm with NVIDIA Base Command Manager, Bright Cluster Manager, or another cluster-management platform

Aufgaben

• Own Slurm support cases from initial investigation through resolution for customers running production AI and HPC clusters
• Diagnose complex problems involving slurmctld, slurmd, slurmdbd, job scheduling, node management, resource allocation, accounting, authentication, and high availability
• Solve Slurm configuration and policy issues involving partitions, reservations, priorities, fair-share, quality of service, backfill, preemption, GRES/TRES, cgroups, and job constraints
• Investigate performance, reliability, and scalability issues using logs, diagnostic data, configuration analysis, reproductions, and source-level debugging when required
• Isolate problems across Slurm and dependencies including Linux, MUNGE, databases, networking, parallel storage, containers, GPUs, and cluster-management systems
• Advise customers on Slurm configuration, upgrades, operational practices, system-resource management, and safe recovery from production incidents
• Collaborate with engineering teams by producing technical descriptions, reproducible test cases, and defect reports
• Develop guides, knowledge-base articles, diagnostic tools, and internal training to strengthen Slurm expertise across the support organization
