Join us and make YOUR mark on the World!

Come join Lawrence Livermore National Laboratory (LLNL) where we apply science and technology to make the world a safer place; now one of 2020 Best Places to Work by Glassdoor!

We have multiple openings for a Computational Physicist/Engineer to work on next-generation fissile materials production modeling and simulation usingstate-of-the-art adaptive computing technologies to integrate models with advanced data analytics and machine learning. You will develop models to enable simulation of proliferation processes, detection of early signatures, and accurate assessment of possible proliferation activities.This position is in the Applied Physics Section in the Physics Division.

Essential Duties
- Learn underlying physics and operational procedure of existing suite of computational models for fissile-materials production.
- Enhance existing and develop new computational models for processes and components associated with fissile materials production using a new adaptive computing environment, coupled to high-performance computing capabilities, as needed.
- Use hierarchy of complex computational models to provide expert input and technical advice to national security nuclear analysts.
- Apply machine learning and statistical analysis to computer simulation outputs to couple simulation codes, to perform and analyzelarge-scale statistical studies, and to generate synthetic for machine-learning models.
- Maintain an awareness of technical literature in assigned areas.
- Periodically, prepare written analyses and verbal briefings that capture and communicate research results.
- Publish research results in technical and/or peer-reviewed scientific journals, and present results at technical meetings and/or external conferences.
- Occasional travel as necessary to interact with sponsors and collaborators.
- Perform other duties as assigned.

- PhD in nuclear engineering, physics, chemical engineering, computational sciences, related field or the equivalent combination of education and significant professional experience.
-Ability to develop complex computer codes.
-Advanced knowledge andsignificant experience in developing computational models and simulations.
- Significant experience authoring technical and scientific reports and publications, and delivering scientific presentations.
- Advanced verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information and provide advice to management and external sponsors.
- Ability to travel off-site for sponsor and collaborator interaction.
Desired Qualifications
- Experience with adaptive computation environments, high-performance computing, artificial intelligence, machine learning, and/or data analytics.
- Advanced knowledge and significant experience with the scientific and technological issues associated with national security in one or more of the following areas: nuclear fuel cycle, advanced technology/process model development, isotope production, data analytics, fluid flow, industrial chemical facilities, foreign weapon programs, or related emerging technologies.

Pre-Employment Drug Test: External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test. This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

Security Clearance: This position requires a Department of Energy (DOE) Q-level clearance. Also, you must have the ability to obtain and maintain Sensitive Compartmented Information (SCI) access.If you are selected, we willinitiate a Federal background investigation to determine if youmeet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing. Q-level clearance requires U.S. citizenship. If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted.

Note: This is a Career Indefinite position. Lab employees and external candidates may be considered for this position.
