• Present and disseminate research results at scientific conferences and in peer-reviewed publications, in both open and classified environments, internal and external to LLNL.  Positively represent the Program and Laboratory demonstrating advanced verbal and written skills. Responsibilities may also include interacting with external stakeholders, both at NNSA and across the broader interagency, via offsite assignments.
• Develop expertise in interrelated fields of physics important to weapons assessment and certification.
• Lead independent work conducting applied physics research.  Lead and mentor staff as part of a multidisciplinary team.
• Lead top quality research in relevant areas of physics and engineering.  Problem-solve and make decisions necessary to independently address challenging problems.
• Recognize and support plans to promote and foster a culture of inclusion, diversity, equity, and accountability within the workplace.
• Perform other duties as assigned.

Additional job responsibilities at the SES.4 Level

• Assess the highly complex physics interactions that take place in a nuclear explosion.
• Design and provide in depth analysis of experiments exploring the physics of nuclear explosives.  Define and implement stockpile stewardship for specific weapons systems.
• Simulate weapons phenomena and perform highly advanced weapons assessment and certification tasks using physical models in computer codes.

• Ability to maintain a U.S. DOE Q-level security which requires U.S. citizenship.
• Master’s degree in physics, engineering, or related field or equivalent combination of education and related experience.
• Significant experience conducting applied physics research.
• Demonstrated record of completing outstanding research in relevant areas of physics and engineering.
• Significant experience with advanced computer-based design and analysis of experiments.
• Demonstrated aptitude for mastering new fields of physics; a record of creativity, physical insight, and breadth of understanding in advanced applications of complex physical processes.
• Significant experience in using advanced computational facilities for applied physics analysis.
• Advanced verbal and written communication and presentation skills necessary to author advanced technical and scientific reports, publications, invited papers, and to deliver scientific presentations.
• Significant experience working effectively independently and in a multidisciplinary, team-research environment.  Demonstrated self-motivation and initiative in addressing challenging problems.
• Demonstrated ability/commitment to promote and value inclusion, diversity, equity and accountability principles in the workplace.

Additional qualifications at the SES.4 Level
