Senior Mechanical Engineer, Vacuum Systems

Job ID 3324 Date posted 08/10/2022

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

The EIC Vacuum Group has an opening for a senior level Mechanical Engineer to help design and develop components for the multiple large vacuum systems required for the Electron-Ion Collider being built at BNL. The selected candidate will focus on developing and optimizing thin film coatings which will be required for large quantities of accelerator components. This effort will include the development and commissioning of the required coating and support equipment. After the development phase, this position will evolve into supporting the buildup and transfer of the optimized coating process to an on-sight production facility which will be required to support the project needs. In addition to coatings, the EIC project has complex and unique challenges which will require creative solutions and close collaboration with the other technical engineering groups. The chosen candidate will fill a key role in developing the solutions critical to the success of the project and will continue to support these through the production and commissioning phases of the project. Join BNL at the beginning of this ground-breaking scientific and engineering project and become part of the team building this scientific discovery machine.

Essential Duties and Responsibilities:

  • Work directly with physicists to develop, optimize, and test specialized coatings for use inside super conducting magnets
  • Manage the various aspects and develop project plans including schedules with needed resources and budgets
  • Oversee the development of the required production coating facility
  • Create documentation and train technicians to ensure uniformity and consistency throughout the production process
  • Coordinate a variety of technical staff for design, fabrication, assembly, testing, and installation of equipment
  • Work closely with scientific staff as well as other engineering groups to develop solutions to complex problems and integration issues
  • Prepare and present material as required for design reviews
  • Prepare job orders, requisitions, and cost estimates
  • Maintain a safe and respectful workplace environment

Position Requirements

Required Knowledge, Skills, and Abilities:

  • Bachelor’s Degree in mechanical engineering or related field
  • 7-10+ years of progressively responsible related work experience
  • Experience with creative engineering projects, working hands-on with mechanical equipment, and collaborating with a team to develop and build unique equipment
  • Experience with 3D CAD molding software (Creo preferred)
  • Knowledge of material properties, manufacturing/machine shop processes, welding, hardware & component choice, manufacturing, installation, and dimensioning and tolerances
  • Proficient computer skills including the use of Microsoft Office (Word, Excel, PowerPoint)
  • Excellent organizational, written, verbal and presentation skills
  • Detail oriented and capable of following strict policies and procedures to ensure hardware and personal protection

Preferred Knowledge, Skills, and Abilities:

  • Experience with thin film coating development (magnetron sputtering preferred)
  • Master’s degree in Engineering or Physics
  • Experience designing UHV systems
  • Demonstrated ability to positively interact and support contractors, vendors, project management and procurement professionals
  • Knowledge of optical metrology methods (XPS, SEM, XRD, etc.)
  • Basic knowledge of instrumentation and control systems


  • Occasional domestic and/or international travel
  • Selected candidate will be placed at the appropriate level based on the depth and breadth of relevant engineering knowledge, skills, and experience.

Environmental, Health & Safety Requirements:

  • Must be comfortable working in industrial, construction and radiation environments
  • Will require occasional climbing ladders, moderate lifting, working in the vicinity of operating machinery, exposure to noise, and the ability and willingness to wear proper PPE
  • Will be required to become a qualified Radiation Worker
  • May be required to occasionally work off-hours, nights and/or weekends to support mission critical projects
