Our Cadre5 Lab Partners division has partnered with the Information Technology Services Directorate (ITSD) at Oak Ridge National Laboratory (ORNL) to recruit a Linux Systems Engineer to join the Research and Development Systems Engineering group. The R&D Systems Engineering group exists to facilitate company goals through systems engineering, integration, and support for the research community. They run clusters, servers, workstations, and other services where science happens at ORNL.
ORNL delivers scientific discoveries and technical breakthroughs needed to realize solutions in energy and national security and provides economic benefit to the nation. This premier research institution located near Knoxville in Oak Ridge, TN, addresses national needs through impactful research and world-leading research centers.
The TeamThe team is responsible for facilitating R&D projects. They provide design, deployment, optimization, monitoring, and tooling support across multiple clustered infrastructures for the research organizations that they support. They support clusters that range in scope from just a handful of nodes to 40,000 cores.
What does the ideal teammate look like and what will you be doing?The primary goal is to partner with research organizations to enable research excellence and delivery at ORNL. They work with other clustered computing and HPC groups to help research programs identify the best solutions for their needs. When the team builds environments for their customers, you will work with the team to design, implement and maintain the systems for customers from inception to retirement.
This role will advocate and promote HPC and clustered computing services to researchers who process large data sets and/or develop code as a part of their project. You will be responsible for the availability, performance, scalability, and security of production systems. You should have a strong desire to push the envelope and identify new technologies and opportunities and be able to communicate the potential benefits of those choices to others within the team and our research partners. The team heavily utilizes automation and monitoring solutions to minimize day-to-day maintenance and you should always be looking for opportunities to optimize system management practices or system performance. As the primary SMEs for these systems, you will work with technical POCs for the programs supported to install and help tune the performance of various scientific toolsets. You should be a collaborative and energetic team member who thrives on the opportunity to build trust and credibility, and ultimately become a trusted advisor to the research teams.
The group optimizes workflows and monitoring solutions to take advantage of the 24/7 operations staff, which significantly reduces the need for off-hours support. They also offer a flexible work schedule and utilize Email, Jira, Confluence, Teams, Slack, and other collaboration solutions to stay in contact.
