Physics Consulting Jobs in California (NOW HIRING)

Location: Lawrence Berkeley National Laboratory (LBNL) – Berkeley, CA
Project: Advanced Light Source Upgrade (ALS-U)
Contract Environment: U.S. Department of Energy (DOE)
Anticipated Period of Performance: Approximately 3 years, beginning upon contract award and continuing through completion of ALS-U Dark Time activities

We are seeking an experienced Radiation Physicist / Radiation Protection Engineer to provide professional radiation physics consulting services in support of the Advanced Light Source Upgrade (ALS-U) Project at Lawrence Berkeley National Laboratory.

The successful candidate will provide technical expertise supporting accelerator, beamline, and associated facility systems throughout design, procurement, fabrication, installation, testing, commissioning, and operational readiness.

This position will perform radiation physics and radiation protection engineering activities including radiation shielding evaluations, radiation transport analyses, ALARA evaluations, radiological hazard assessments, technical and design reviews, field assessments, and radiation safety support.

• Provide radiation protection engineering expertise for ALS-U systems and facilities.
• Perform and/or review radiation shielding evaluations.
• Perform radiation transport analyses.
• Conduct ALARA (As Low As Reasonably Achievable) evaluations and planning.
• Participate in radiation protection design reviews.
• Evaluate radiological hazards associated with accelerator systems and experimental equipment.
• Provide technical recommendations supporting engineering and design decisions.
• Perform accelerator radiation safety evaluations throughout the project lifecycle.
• Support safety-basis documentation.
• Review accelerator modifications and evaluate proposed changes for potential radiological impacts.
• Support configuration-management activities affecting radiation safety.
• Participate in technical reviews of engineering drawings, specifications, design packages, procurement documentation, installation plans, test procedures, operating procedures, and readiness documentation.
• Perform or support radiological hazard assessments for project work.
• Evaluate potential worker radiation exposure.
• Review work-planning documentation and recommend appropriate engineering and administrative controls.
• Develop, review, and revise radiation protection documentation, including technical reports, engineering calculations, procedures, technical basis documents, engineering memoranda, design-review comments, compliance documentation, and lessons learned.
• Provide field support during installation, testing, commissioning, and operational readiness activities.
• Conduct walkdowns and field observations and assist with resolution of technical radiation-protection issues.
• Evaluate changing field conditions and provide recommendations supporting safe execution of work.
• Support compliance with applicable federal, DOE, LBNL, and ALS-U requirements.
• Participate in DOE reviews and independent assessments.
• Prepare technical presentations, review materials, responses, corrective actions, and supporting documentation.
• Coordinate with the ALS-U Project Office, Engineering, Quality Assurance, Procurement, EH&S, Systems Engineering, and other project stakeholders.

Requirements

Strong candidates should demonstrate professional experience in several of the following areas:

• Radiation physics
• Radiation protection engineering
• Accelerator radiation safety
• Radiation shielding calculations and evaluations
• Radiation transport analysis
• ALARA evaluations and planning
• Radiological hazard assessments
• Worker exposure evaluation
• Accelerator and/or beamline systems
• Radiation protection design
• Engineering calculations
• Technical basis documentation
• DOE radiation protection requirements
• Technical and engineering design reviews
• Operational/readiness reviews
• Field radiation assessments and measurements
• Configuration management affecting radiation safety

The ideal candidate combines a strong radiation-physics or radiation-protection engineering background with practical experience supporting complex technical facilities.

Experience within accelerator, national laboratory, DOE, nuclear, high-energy physics, research facility, or similarly regulated environments would be particularly relevant to the ALS-U mission.

The individual should be comfortable moving between analytical engineering work and field execution—from performing shielding and transport analyses and reviewing technical designs to conducting field walkdowns and supporting installation, testing, commissioning, and readiness activities.
