Sr. Health Physicist

We have an opening for a Sr. Health Physicist in the Radiation Protection Functional Area. In this role, you will provide an advanced level of health physics (HP) support to ensure radiation safety programs at LLNL are effective and compliant, sometimes working with parameters that may not be well defined. This position will also provide solutions to complex HP issues/problems and provide guidance and/or leadership to ES&H Team radiological control personnel (e.g., health physicists, technicians) in the area of field operations. This position is in the Environment, Safety and Health (ES&H) Directorate.

This position may offer a hybrid schedule, which includes the flexibility to work from home one or more days per week, after a probationary period. The specifics of the hybrid schedule, including the exact number of days required in the office and virtual work options may vary based on the needs of the team and the organization. 

This position will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level. 

You will

• Evaluate and provide HP input on radiation safety policies and procedures that are complex and may not be well defined. Lead efforts to draft, review, and maintain related institutional documents and other contents.
• Conduct assessments and audits necessary to comply with applicable regulatory requirements independently, with minimal direction. Lead audits, inspections and site verifications by internal and external entities.
• Act as the point of contact (POC) for radiation protection program functional elements (e.g., contamination control, posting and labeling, radiation generating device, etc.). Lead the development and maintenance of associated program documents and processes, routinely interacting with professional colleagues, internal senior management, and sponsor organizations across and outside the Laboratory on advanced HP technical areas and projects/programs.
• Provide guidance and clarification on a diverse range of complex issues and analyze & resolve radiation safety program implementation questions from field radiological control personnel on matters related to HP field operations.
• Apply advanced technical knowledge to streamline processes.
• Respond to radiological emergencies and incidents on site. Participate in event investigations and make recommendations to all levels of management to prevent recurrence.
• Provide periodic support to Programmatic field operations.
• Lead, develop, and present selected training courses in radiation safety (or related topics).
• Perform other duties as assigned.

Additional job responsibilities, at the TSS.4 level 

• Act as a subject matter expert for radiation protection program, leading & directing tasks, setting broad visions, acting as a spokesperson for involved programs while working with all levels of internal and external stakeholders.
• Provide solutions to highly complex HP issues that may involve parameters that are intangible and require an in-depth level of analysis.
•  Apply highly advanced knowledge and substantial experience to advance radiation protection methods at the Laboratory.

• Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship. 
• Bachelor’s degree in Health Physics, Nuclear Engineering, Radiation Physics, or Radiation Protection or the equivalent combination of education and related experience.
• Advanced knowledge and significant experience in development, analysis, and refinement of complex health physics procedures engaged in the monitoring and/or leading/mentoring/training personnel and work environments, with knowledge of relevant state and federal regulations and other consensus standards.
• Significant experience with preparing/leading complex technical reports and/or acting as the main POC conducting radiation safety audits and inspections.
• Effective organizational skills with attention to detail necessary to lead multiple tasks in a demanding environment with conflicting priorities, tight and changing deadlines, and frequent interruptions while providing high-level customer service and good follow-through.
• Ability to work independently, under minimal direction as well as in a team environment with a broad cross-section of people and organizations, managing projects, and meeting schedules.
• Advanced analytical, decision-making and problem-solving skills to effectively analyze and solve complex and diverse problems, while offering advice to further streamline processes.
• Advanced verbal and written communication skills necessary to effectively collaborate in a team environment and to present, explain, and advise on complex technical or operational information.

Additional qualifications at the TSS.4 level 

• Highly advanced and substantial subject matter expertise leading &/or working as a spokesperson in a facility engaged in the monitoring of personnel and work environments, with advanced knowledge of relevant state and federal regulations and other consensus standards.
• Substantial experience providing solutions to highly complex HP issues requiring in-depth analysis.
• Significant experience leading health physics work, advancing health and safety standards and radiation protection methods within a large and highly complex environment.

Qualifications We Desire

• Master’s degree in Health Physics, or another closely related technical area.
• Certification by the American Board of Health Physics.
• Experience using MCNP and conducting radiological engineering analyses.
• Active DOE Q Clearance.
• Prior DOE Laboratory or power plant HP operational experience.
• Experience performing job hazard analyses for radiological work.
• Solid understanding of 10CFR835 and 10CFR830 and how to apply that in review of lab situations.

Pay Range

$154,950 - $196,476 Annually for the TSS.3 level
$185,850 - $235,692 Annually for the TSS.4 level

This is the lowest to highest salary we in good faith believe we would pay for this role at the time of this posting; pay will not be below any applicable local minimum wage. An employee’s position within the salary range will be based on several factors including, but not limited to, specific competencies, relevant education, qualifications, certifications, experience, skills, seniority, geographic location, performance, and business or organizational needs.
