Job Description

We have multiple openings for Computational Physicist seeking to pursue challenges relevant to national security in the development of multi-physics simulation codes. You will collaborate as part of an interdisciplinary code development team in advancing the state of the art in large-scale multi-physics simulation. The national security mission involves developing simulation capabilities for Stockpile Stewardship nuclear counter-terrorism conventional weapons and high energy density physics experiments. The code development focus is on models and algorithms for use in high-performance computing on the latest large-scale parallel computing platforms. This position is in the Design Physics Division within the Weapons and Complex Integration (WCI) 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.

In this role you will

• Develop release and maintain models and algorithms using advanced simulation tools to support the physics capabilities based on requirements from a diverse user community.
• Provide technical support informal training and guidance to code users in the application of simulation tools developed.
• Participate in the development of simulation tools as part of a multi-disciplinary team.
• 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 NNSA and across the broader interagency via offsite assignments.
• Perform other duties as assigned.

Additional job responsibilities at the SES.3 Level

• Develop assess and provide in depth analysis of the physics capabilities in support of nuclear weapons simulations using advanced simulation tools to solve complex problems that may not be well defined.
• Collaborate as a technical expert on multidisciplinary team.
• Set specific technical strategies to achieve program goals.

Qualifications

• Ability to maintain a U.S. DOE Q-level security which requires U.S. citizenship.
• PhD in physics mathematics engineering or related field or the equivalent combination of education and related experience.
• Demonstrated technical mastery in one or more science disciplines such as shock hydrodynamics fluid mechanics material behavior particle transport radiation transport plasma physics or chemical processes.
• Experience converting theory into models implementing models and evaluating algorithms and methods for their fitness for a particular task as well as developing new numerical algorithms.
• Experience developing and supporting multi-dimensional numerical simulation.
• Demonstrated creativity and innovation in approaching challenging technical problems.
• Experience with programming in Python FORTRAN C and/or C++ on high-performance and/or heterogenous computer systems.
• Experience working independently and in a multi-disciplinary team-research environment demonstrating self-motivation and initiative in addressing challenging problems.
• Demonstrated verbal and written communication and presentation skills necessary to author technical and scientific reports publications invited papers and to deliver scientific presentations.

Addition qualifications at the SES.3 Level
