Brookhaven National Laboratory (BNL) 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

We are seeking a Mechanical Design Checker to work closely with the mechanical design engineering staff to support a wide range of projects including magnets, vacuum components, accelerator systems and beamlines. The mechanical design group requires a person to check CAD models and drawings. The Mechanical Design checker will also provide technical influence and guidance on the 3D designs.  This will include tolerance studies of each part and overall tolerance stack up of assemblies. Materials include metallics, non-metallics including plastics, and electro-mechanical assemblies. Technologies are machining, forming, welding, 3D printing, etc. 

Essential Duties and Responsibilities:

• Closely work with designers and engineers and provide technical suggestions

• Check CAD Models and Drawings

• Check Bills of Material, Quantities of materials and ensure they match Vendor cataloging

• Check Tolerance Studies

• Complete ECN (Engineering Change Notice)

• Catalog item drawings for customization

• Ensure we follow standard drafting practices

Required Knowledge, Skills, and Abilities:

• High school diploma or equivalent plus 12 years’ similar or comparable mechanical design work experience; OR

• A technical high school certification program (e.g., BOCES) plus 11 years’ similar or comparable mechanical design work experience; OR

• A technical institute or Adult BOCES certification, or Associate Degree in a technical field, or Brookhaven Lab CCI program completion plus 10 years’ similar or comparable mechanical design work experience; OR

• Bachelor’s degree in a technical field plus 6 years’ similar or comparable mechanical design work experience

• Proficiency in 3D design/drafting using Creo or Inventor.

• Experience interpreting and ensuring conformance to drafting standards, including ASME Y14.5, pressure vessel codes and piping.

• Knowledge of welding practices and welding symbol call outs on drawings.

• Working knowledge of engineering fundamentals and handbook formulas, machine shop practices.  

• Demonstrated ability to perform tolerance analysis.

Preferred Knowledge, Skills, and Abilities:

• Experience in specifying drive components such as motors, gears, bearings, actuators, switches, and connectors.

• Knowledge of accelerator magnets, vacuum systems, instrumentation, and beam line hardware.

Environmental, Health & Safety Requirements:

• Will be required to become a qualified Radiation Worker.

• May be required to climb ladders for equipment inspection.

• May require moderate lifting (15-30 lbs.)

• May be required to occasionally work off-hours, nights, or weekends to support mission critical projects.

Other Information:
