Senior Mechanical Engineer, Cryogenics Group

Brookhaven National Laboratory is committed to employee success and we believe that a comprehensive employee benefits program is an important and meaningful part of the compensation employees receive. Review more information at BNL | Benefits Program

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. 

The Cryogenics Group is responsible for upgrading existing cryogenic systems, designing and installing new systems, and operations of these systems that will be part of the Electron-Ion Collider. The existing central plant and existing Hadron Storage Ring cryo-distribution system will be upgraded/renewed and re-used. New 2K satellite systems and new 2K distribution systems will be added to meet EIC requirements.  The cryogenic system cools various superconducting magnets and various superconducting RF cavities throughout the EIC collider complex. 

Position Description 

BNL’s Electron-Ion Collider (EIC) directorate has an opening, in the Cryogenics Group, for a Senior Mechanical Engineer with experience in the engineering and/or operations of equipment and piping systems for chemical plants or cryogenic process plants. Work scope will include upgrades and maintenance of the current central liquid helium processing plant and other cryogenic equipment, as well as the design and planning for future EIC cryogenic systems and equipment. This position has a high level of interaction with an international and multicultural scientific community. 

Essential Duties and Responsibilities: 

• Develop designs of mechanical cryogenic components including cryostats and vacuum jacketed cryogenic piping systems, and designs of warm piping systems that transfer gases to cryogenic components. 

• Perform overall system level engineering, define equipment requirements, prepare equipment purchase specifications and drawing packages, following lab safety standards and national safety and equipment codes. 

• Collaborate with technical experts designing superconducting magnets and RF cavities on requirements, interfaces, and the optimization of cryogenic performance. 

• Manage engineering projects, including overseeing the work of other engineers and designers, and develop project plans including schedules, required resources, and budgets. 

• Work independently and collaborate with other senior engineering and scientific staff for assignments, guidance, and support. 

• Develop purchase specifications, act as technical representative for interfacing and follow up with vendor/fabricator during vendor manufacturing, travel for design meetings and witness tests. 

• Present the engineering and design in design reviews with technical staff.
