• 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

Required Qualifications

• Master's degree or higher in Health Physics, Physics, Nuclear Engineering, Radiation Physics, or a closely related scientific or engineering discipline; or an equivalent combination of advanced education and directly relevant professional experience.
• 5+ years of progressively responsible professional experience in radiation physics, health physics, radiation protection, accelerator radiation safety, or a closely related technical field.
• Demonstrated experience performing radiation shielding evaluations and/or radiation transport analyses for accelerator, beamline, nuclear, research, industrial, or other complex radiation-generating systems.
• Demonstrated knowledge of radiological hazard assessment and radiation-protection principles , including application of As Low As Reasonably Achievable ( ALARA ) principles.
• Experience evaluating radiation hazards associated with the design, installation, testing, commissioning, modification, or operation of complex technical systems or facilities .
• Experience developing or reviewing technical radiation-safety documentation, including shielding calculations, radiation analyses, hazard assessments, procedures, technical-basis documents, compliance documentation, or technical reports .
• Experience interpreting and applying applicable radiation-protection regulations, standards, and technical requirements .
• Ability to independently perform complex technical evaluations and provide defensible radiation-protection recommendations to engineering, project, safety, and technical stakeholders.
• Demonstrated ability to communicate complex radiation-physics concepts and technical findings effectively to multidisciplinary engineering, scientific, project-management, and safety teams.

Strongly Preferred Qualifications

• Direct professional experience supporting an accelerator, synchrotron light source, particle accelerator, beamline, nuclear facility, Department of Energy facility, or National Laboratory .
• 5+ years of accelerator radiation shielding and/or accelerator radiation-protection experience.
• Experience with Monte Carlo radiation-transport modeling , such as FLUKA, Geant4, MCNP, or comparable computational tools.
• Knowledge and practical application of 10 CFR 835, DOE-STD-1098, DOE O 420.2D, and other applicable DOE radiation-protection or accelerator-safety requirements .
• Experience performing radiation-physics evaluations for accelerator and beamline shielding, penetrations, radiation-generating devices, access-control systems, or radiation safety systems .
• Experience supporting engineering and design reviews , including review of drawings, specifications, equipment designs, shielding configurations, installation plans, and test or commissioning procedures.
• Experience supporting accelerator commissioning, radiation measurements, readiness reviews, operational readiness activities, or facility authorization .
• Experience developing or maintaining formal radiation-protection programs, technical-basis documents, or facility radiation-safety requirements .
• Experience interacting with DOE, regulatory authorities, independent reviewers, or external technical review teams .
• Previous experience within the DOE National Laboratory complex .
• Certification by the American Board of Health Physics (CHP) or eligibility for certification is highly desirable.

Ideal Candidate

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.
