Senior Cryogenics Process Engineer

Job ID JR100913 Date posted 02/28/2024


The mission of the Collider-Accelerator Department (C-AD) is to operate, maintain, improve, and upgrade the suite of electron, proton, and heavy ion accelerators used to carry out a program of accelerator-based experiments at Brookhaven National Laboratory (BNL). To support this program, the C-AD must design, fabricate, assemble, test, install, and operate unique research equipment to generate, transport, transfer, accelerate, focus, track, collide, and absorb high intensity particle beams up to energies of 250 GeV.  This includes a combination of custom designed and built parts and vendor produced components developed by a collaboration of the C-AD scientific, engineering, and technical staff. The C-AD supports an international user community of over 1,500 scientists. The C-AD performs all these functions in an environmentally-responsible and safe manner, under a rigorous conduct of operations approach.


Within the Collider-Accelerator Department, the Accelerator Division Cryogenic Engineering Group has an opening for a senior lead-level cryogenic engineer with experience in the analysis, design, and operation of helium liquefaction and refrigeration systems and equipment for cooling superconducting devices.  Work scope will include upgrades and maintenance of current RHIC cryogenic equipment as well as the design and planning for future EIC cryogenic systems and equipment. The role also involves participating in the daily operations of the RHIC cryogenic plant through maintenance, trouble shooting, and repair of deployed equipment.

This position has a high level of interaction with an international and multicultural scientific community.

Essential Duties and Responsibilities:

  • Managing individual engineering projects and developing project plans including schedules, needed resources, and budgets.

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

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

  • Oversight of less experienced engineers during the engineering and design of cryogenic components, and develop designs of cryogenic components inside cryostats, of vacuum jacketed cryogenic piping system and warm piping systems between equipment and piping supports.

  • Collaborate with technical staff on the mechanical interfaces and cryogenic requirements during the design of Superconducting RF cavity and superconducting magnet cryomodules.

  • Develop purchase specifications, interface and follow up with vendor/fabricator during vendor manufacturing, travel for design meetings and witness tests.
