Senior Mechanical Designers and Mechanical Design Engineers

Job ID 2324 Date posted 10/19/2020

Brookhaven National Laboratory ( delivers discovery science and transformative technology to power and secure the nation’s future. Brookhaven Lab is a multidisciplinary laboratory with seven Nobel Prize-winning discoveries, 37 R&D 100 Awards, and more than 70 years of pioneering research. The Lab is primarily supported by the U.S. Department of Energy’s (DOE) Office of Science. Brookhaven Science Associates (BSA) operates and manages the Laboratory for DOE. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University.

Organizational Overview

Brookhaven National Laboratory was recently chosen as the building site for the Electron-Ion Collider (EIC), a one-of-a-kind nuclear physics research facility.  The EIC will be a discovery machine for unlocking the secrets of the “glue” that binds the building blocks of visible matter in the universe. The machine design is based on the existing and highly optimized RHIC Ion-Ion collider.   It will consist of two intersecting accelerators, one producing an intense beam of electrons, the other a beam of protons or heavier atomic nuclei which are steered into collisions.  Beyond sparking scientific discoveries in a new frontier of fundamental physics, the Electron-Ion Collider will trigger technological breakthroughs that have broad-ranging impact on human health and national challenges.

Position Description

BNL’s new EIC division has immediate openings for Senior Mechanical Designers and Mechanical Design Engineers to join our growing Design and Documentation Group. Under the technical direction of the group leader and other engineers/scientists, you will play a key role in designing the equipment to be used in our new accelerator. This equipment includes magnets, power supplies, RF systems, vacuum equipment, accurately positioned support structures, remote drive systems, lifting fixtures, and civil facilities including building layouts and water/air cooling systems.  The assignments you will work on will usually be on a project basis, which will require a high degree of initiative and judgement to plan, coordinate, and perform your design efforts.

Join the BNL EIC team and be part of building the next discovery machine for science!
