Requisition Id 5805 

Who are we looking for?

The Research and Development Systems Engineering (RDSE) Group in the Information Technology Services Division (ITSD) at Oak Ridge National Laboratory (ORNL) seeks to hire a Linux Systems Engineer. In this position, this individual will be embedded within our Atmospheric Radiation Measurement (ARM) group in the Energy and Environmental Sciences Directorate doing Linux Server.


Who are we?

Born in secrecy under the Manhattan project of World War II, ORNL has emerged as the U.S. Department of Energy’s largest open science and energy laboratory. Innovation at ORNL is powered by literally thousands of top tier scientists, engineers, and technicians with access to world class facilities including the world’s fastest supercomputer (Summit). We are engaging in open, peer reviewed, interdisciplinary research across multiple application domains from neutrons to biology, from nuclear to manufacturing, and nanophase to national security.


What will you be doing?

The R&D Systems Engineering Group focuses on supporting researcher’s IT needs. Staff charge directly to projects or programs, and not to a centralized budget. Our goal is to enable research while protecting ORNL assets, especially from cyber incidents.

As a Linux Systems Engineer, you will be performing Linux Server and Oracle ZFS System support. You will help maintain system health and provide system analysis to the customer. You will document any work done in accordance to the customer’s direction.

Working at ORNL

ORNL has an innovative and fast paced culture that rewards open source software development, has a flexible work schedule, and very competitive pay with industry. On any given day, after listening to a talk from a Nobel Laureate, you can eat at two full-service cafés’, go to a spin class, or visit the full-service primary care clinic, all without leaving our campus.


Living in East Tennessee

It’s easy to overlook everything East Tennessee has to offer if you haven’t had the opportunity to spend time here. From spending your weekends downtown at Knoxville’s farmers market, the Rhythm n’ Blooms Music Festival, or the Dogwood Arts Festival, to some of the best hiking, kayaking, and camping in the U.S., not only in the Great Smoky Mountains National Park but all over the greater area, East Tennessee has something to offer everyone.
