Application Engineer II - HPC Systems & Scheduler Administrator

WCL Group; Wade Hampton (SC); In loco; USD 72.000 - 80.000; Tempo pieno

Descrizione del lavoro

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.

Competenze

• 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.

Mansioni

• 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.

POSITION OVERVIEW – Application Engineer II - HPC Systems & Scheduler Administrator

You’ll keep the Linux servers behind a large high-performance computing platform running well, and you’ll be the expert on Slurm, the software that decides which simulation jobs run, where, and when. You’ll set up and tune the scheduler, so jobs spend less time waiting in line, manage the software environments engineers run their simulations in, and look after the Linux virtual desktops that engineers use.

You’ll also set up monitoring and alerts, track down performance bottlenecks in the network and storage, and handle Linux user accounts and access, working closely with the DT team.

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 Quality of Service (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

• 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
• Support Linux-side user provisioning, group management, SSH key governance, and sudo/privilege management in collaboration with the DT team's identity management processes

REQUIRED QUALIFICATIONS/SKILLS

• 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. Final offers are contingent on receiving this authorization.
