Full description
IT@JH Research Computingis seeking a Sr. HPC Systems Engineer who will design, build, and maintain advanced high-performance computing environments supporting Johns Hopkins University’s research mission. This position focuses on the reliable operation, configuration, and optimization of HPC and AI systems, including multi-node CPU and GPU clusters, high-speed InfiniBand and Ethernet networks, and large-scale parallel and object storage. The engineer implements and automates secure, efficient, and reproducible computing platforms used by faculty, researchers, and students across diverse scientific disciplines. Assignments include both ticket-based support and project-based deployments. The role operates with moderate independence, collaborating closely with the IT Architect, Research Computing, and reporting to the IT Manager for Research Computing to ensure scalable, sustainable, and high-performance systems that enable cutting-edge scientific discovery.
Specific Duties & Responsibilities
- Support and administer production systems used by researchers and Research Centers.
- Provide technical leadership/project management for system configuration, implementation, management, and user support for both new and existing systems.
- Research and recommend new functionality for HPC management and administration tools by exploring system-wide impacts, working with functional users to define current and future processes.
- Expertise with architecting, operating, and debugging large scale HPC network and storage infrastructure, including MPI, NCCL, RDMA, Infiniband, and parallel file systems
- Works with scientific support specialists and assigns tasks and provides oversight as appropriate to HPC engineering team to support scientific researchers who use a broad spectrum of applications from diverse fields.
- Analyze results of server monitoring and implement changes to improve performance, processing, and utilization.
- Propose, maintain, and enforce policies, practices and security procedures.
- Provide break/fix support, setup/installation support, escalation support, and solutions support.
- Collaborate closely with a variety of stakeholders, both internal and external, on all aspects of projects.
- Other duties as assigned.
In Addition to the Duties Described Above
- Deploy, configure, and maintain large-scale Linux-based HPC clusters comprising CPU and GPU nodes, high-speed interconnects, and parallel file systems.
- Implement and optimize workload schedulers (Slurm) and job submission policies to maximize system throughput and fair-share usage.
- Administer and monitor distributed storage systems (GPFS, Lustre, WekaFS, Ceph, MinIO) to ensure reliability and performance across multi-petabyte environments.
- Maintain high-speed fabric and network infrastructure (Infiniband, Ethernet) to support low-latency data transfer and MPI workloads.
