HPC Scheduler Engineer II — Slurm Specialist

WCL Group; Wade Hampton (SC); On-site; USD 72,000 - 80,000; Full time

Job summary

WCL Group is seeking an Application Engineer II to manage and optimize a large HPC cluster in Greenville, SC. You will be the expert on Slurm, tuning the scheduler, managing environments, and maintaining Linux VDI for engineers running simulations.

You will implement monitoring and alerting (Ganglia, Grafana/Prometheus, CloudWatch), prune bottlenecks, and coordinate with the DT team on access, security, and IAM processes. This is a 1-year contract with potential extension or conversion.

Qualifications

• Since this role involves access to U.S. export‑controlled information, candidates must be able to obtain authorization for that access from the U.S. Government.

Responsibilities

• Manage OS-level configuration, patching, and hardening of HPC compute nodes, login nodes, and head nodes, ensuring stability and security compliance in coordination with the DT team's cybersecurity policies.
• Serve as the primary subject matter expert for the Slurm workload manager, managing partition configurations, node scheduling policies, fairshare/priority weighting, reservation management, and QoS tiers.
• Manage environment module frameworks (e.g., Lmod/Environment Modules), compiler toolchains, MPI libraries, and application runtime environments in support of engineering simulation codes.
• Administer and maintain the Linux virtual desktop (VDI) environment, including image lifecycle, user session management, OS configuration standardization, and application delivery to Linux desktop users.
• Deploy and maintain comprehensive system monitoring (e.g., Ganglia, Grafana/Prometheus, CloudWatch) for compute, scheduler, and Linux VDI environments, and establish alerting thresholds and on-call response protocols with the DT team.
• Design and tune scheduling configurations to maximize throughput and minimize queue latency, and develop a strategy to prioritize HPC usage across the user community and reduce queue times.
• Profile and tune system-level performance bottlenecks, including network fabric (e.g., EFA/InfiniBand), I/O subsystems, and memory bandwidth, and collaborate with the HPC Performance Engineer on application-level profiling.
