Please note that the pay range information is a general guideline only. Many factors are taken into consideration when setting starting pay including education, experience, the external labor market, and internal equity.

We are seeking exceptional Physical Scientists and Engineers with backgrounds in fields such as plasma physics,radiation transport, atomic physics, nuclear physics, physical chemistry, condensed matter physics, computational physics, or hydrodynamics. Our national-security mission encompasses aspects of computational, theoretical, and experimental physics associated with the complex processes of nuclear explosives. Under limited direction, you will be responsible foradvancing our understanding and developing methodologies for important national-security challenges. This position is in the Design Physics Division within the Strategic Deterrence Directorate.

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

• Assess the complex physics interactions that take place in nuclear explosion.
• Design and provide analysis of experiments exploring the physics of nuclear explosives.
• Simulate weapons phenomena and perform weapons assessment and certification tasks using physical models in computer codes.
• Define and implement stockpile stewardship for specific weapons systems.
• Present and disseminate research results at scientific conferences and in peer-reviewed publications, in both open and classified environments, internal and external to LLNL. Responsibilities may also include interacting with external stakeholders, both at DOE/NNSA and across the broader interagency, as well as via offsite assignments.
• Develop expertise in interrelated fields of physics important to weapons assessment and certification.
• Travel minimally or substantially based on needs of projects.
• 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.3 Level

• Independently develop, assess and provide in depth analysis of the complex physics interactions that take place in nuclear explosion where problems may not be well defined.
• Work as technical expert on multidisciplinary team.
• Guide the analysis and lead the design of experiments exploring the physics of nuclear explosives.

• Ability to obtain and maintain a U.S. DOE Q-level security clearance which requires U.S. Citizenship.
• PhD in physics, engineering, or a related field or equivalent level of demonstrated knowledge.
• Demonstrated record of completing outstanding research in relevant areas of physics and engineering.
• Experience with 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 applications of complex physical processes.
• Experience in using advanced computational facilities for applied physics analysis and conducting applied physics research.
• Proficient verbal and written communication and presentation skills necessary to author technical and scientific reports, publications, invited papers, and to deliver scientific presentations.
• 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.3 Level

• Advanced knowledge of physics, engineering, or a related field.
• Significant experience and ability to lead independent work conducting applied physics research.
• Demonstrated record of leading top quality research in relevant areas of physics and engineering.

Please include a personalized cover letter with your application, highlighting your qualifications and why you're interested in this position.
