Network Engineer I

Network Engineer I Job Summary The Center for High Performance Computing (CHPC) is a cornerstone of innovation at the University of Utah. We play a vital role in enabling scientific research at the campus, state, and national levels by providing large‑scale computational and data services, alongside creative network services. From climate modeling to drug discovery, CHPC empowers researchers to solve complex problems through a massive ecosystem of 50,000+ CPU cores, 1,000+ GPU resources, and 50 PB+ of storage. CHPC seeks a network engineer to support connectivity both internally and externally to multiple remote environments. The position is full‑time staff with benefits and requires 90+% on‑site attendance. The primary work location is the University of Utah Downtown Data Center with associated work at the home office on the university campus. CHPC also has a small presence at a data center in St. George, UT where occasional work may need to be performed. The network engineer will be responsible for installation, maintenance, and documentation of the CHPC Ethernet and InfiniBand networks. This work involves all aspects of network design, engineering, and administration. Physical work includes cabling, fiber plant, equipment installation, physical maintenance, relocation and equipment retirement at all CHPC locations. Administration includes configuring and monitoring network equipment, initial setup, daily changes, maintenance, and troubleshooting necessary to provide a stable, reliable, and resilient network. The engineer will also maintain CHPC’s network segments that require high security controls as part of CHPC’s regulated research computing environments. At CHPC, we foster a positive, collaborative environment. As part of the team, you will have the opportunity to interact and cross‑train with diverse technical groups—including computation, storage, virtualization/cloud, software engineering, networking, and user services—while being encouraged to experiment and innovate with emerging technologies. Responsibilities The network engineer will work with other network colleagues and engage closely with CHPC staff to help design and provide solutions that will support computational research throughout the university. This work requires the ability to listen and learn about project requirements and then work collaboratively to provide solutions that are agreeable to CHPC staff, management, and users. This work also requires the ability to produce comprehensive and accurate documentation with attention to detail. The successful candidate will have experience working on various networking equipment using command line interfaces and experience automating these interfaces. The successful candidate will have, or be able to develop, skills across vendor products from Cisco, Arista, Dell SONiC, HP, and PaloAlto.
