Cryogenic Engineer

The Berkeley Lab's Engineering Division is hiring a Cryogenic Engineer to provide technical expertise in cryogenic technology for scientific and engineering projects. The role focuses on applying thermodynamics, heat transfer, fluid mechanics, systems and controls in cryogenics to develop innovative solutions that meet experimental and scientific requirements. Responsibilities include designing, developing, and managing sub-projects within larger research programs at Lawrence Berkeley National Laboratory (LBNL), with tasks ranging from conceptualization to implementation. This is a dynamic, matrix-based position, requiring flexibility as assignments evolve.

What You Will Do:

• Collaborate with a multidisciplinary team to meet scientific, cryogenic, mechanical, vacuum, instrumentation, controls, and safety requirements.
• Design, analyze, develop specifications, and oversee procurement, fabrication, installation, and testing of cryogenic systems and equipment.
• Conduct complex analyses (thermal, hydraulic, structural, cryogenic process, cryogenic safety, process hazards) using tools like FEA, CFD, and HAZOP.
• Document and communicate findings through reports, presentations, drawings, and publications; participate in reviews and meetings.
• Assist colleagues beyond immediate responsibilities and mentor post-doctoral researchers and students.
• Serve as a resource for peers and contribute innovative solutions to lab needs.
• Comply with EH&S policies and foster a safety-conscious culture.
• Promote IDEA (inclusion, diversity, equity, and accountability) initiatives.

Additional Responsibilities as needed:

• May assume a critical role in a particular component of larger projects/programs.

What is Required:

Cryogenic Engineer Level 2:

• B.S. with 2+ years of engineering experience, in mechanical engineering or a related engineering field.
• Strong background in thermodynamics, fluid dynamics, and heat transfer.
• Experience in cryogenic engineering, particularly in R&D of systems/components for superconducting technology and troubleshooting cryogenic issues.
• Design and development experience in one or more of the following areas:
  
  
  
  • Helium refrigeration/liquefaction systems (4K or below)
  • Helium recovery/purification systems
  • Cryocooler-based cryostats (4K, 20K)
  • Hydrogen liquefaction and transfer systems for SC magnets, nuclear science, and physics applications.
  
  
  
  
• Experience solving complex thermal, structural, hydraulic, or cryogenic processes using FEA, CFD, HAZOP, or similar software.
• Proficient in 3D design with PTC Creo, Solidworks, or similar tools.
• Ability to contribute to cryogenic experimental activities and collaborate in multidisciplinary teams.
• Strong organizational, prioritization, and communication skills (written and verbal).
• Expertise in analyzing complex issues and selecting appropriate methods/criteria.

In Addition to the Above, Cryogenic Engineer Level 3:

• B.S. with 5+ years or M.S. with 3+ years of experience in mechanical or related engineering.
• Experience in planning, coordinating, and managing technical projects, including cost and schedule formulation.

Desired Qualifications:

Cryogenic Engineer Level 2:

• Knowledge of ASME Pressure Vessel and Piping Codes, and pressure safety device standards.
• Experience with process hazard analysis (HAZOP).
• Proficient in AutoCAD Plant 3D for creating/designing process P&IDs.
• Knowledge of machining, fabrication, electromagnetics, structural mechanics, and data analysis/visualization.

In Addition to the Above, Cryogenic Engineer Level 3:

• Ph.D. in mechanical engineering or a related engineering field preferred, with cryogenic related dissertation project or on-job experience.
• Management experience supervising technical staff or students.

Salary:

Cryogenic Engineer Level 2:

The expected salary for this position is $106,000.00 - $129,000.00, which fits into the full salary of $94,164.00 - $158,856.00 annually depending upon the candidate's skills, knowledge, and abilities, including education, certifications, and years of experience.

Cryogenic Engineer Level 3:

The expected salary for this position is $130,000.00 - $158,000.00, which fits into the full salary of $115,176.00 - $194,340.00 annually depending upon the candidate's skills, knowledge, and abilities, including education, certifications, and years of experience.

Notes:

• This is a full-time 2-year, term appointment with the possibility of extension or conversion to Career appointment based upon satisfactory job performance, continuing availability of funds and ongoing operational needs.
• This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
• Work will be primarily performed at: Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.
