Mechanical Designer (STS)

GEM Technology
Oak Ridge, TN Full Time
POSTED ON 4/21/2026
AVAILABLE BEFORE 5/6/2026

We are seeking a Mechanical Designer to produce high quality engineering design packages for components and subsystems. The position resides in the Design Services group within the Second Target Station (STS) Project at Oak Ridge National Laboratory (ORNL).

As part of the Design Services group, you will have the opportunity to engage in the design of complex, integrated mechanical systems, many of which are first-of-a-kind or one-of-a-kind. In this role, you will work alongside other designers, engineers, and scientists to fully develop these component and subsystem designs. You will be responsible for developing component and subsystem designs and detailed fabrication drawings. You will support the responsible engineer in preparing technical specifications and other procurement-related documents. In addition to producing your own design packages, a Senior Mechanical Designer will be responsible for reviewing and checking the work of peer designers.

About the Second Target Station Project:

The Second Target Station (STS) is a >$2Billion Department of Energy project to be constructed at the ORNL Spallation Neutron Source (SNS) over the next decade. The STS will provide wholly new capabilities for the study of a broad range of materials with neutron scattering and support thousands of users from the physical, materials, and applied sciences as well as industry. The science capabilities provided the STS will complement those of the two existing neutron scattering user facilities at ORNL, the First Target Station (FTS) of the SNS and the High Flux Isotope Reactor (HFIR). The STS will deliver the highest peak brightness cold neutrons in the world, which together with advances linear accelerator technology, high powered targets, moderators, and neutron instrumentation, will ensure U.S. leadership in neutron scattering for decades to come. Please see http://neutrons.ornl.gov/sts for more information.
