Science and Technology on a Mission!

For more than 60 years, the Lawrence Livermore National Laboratory (LLNL) has applied science and technology to make the world a safer place.

We have an opening for a Research Scientist. You will develop and maintain nuclear data infrastructure codes and application programming interfaces (APIs), as well as interact with nuclear theorists to fulfill the needs of our programs. This position is in the Nuclear Data and Theory group of the Nuclear and Chemial Sciences Division.
 
Essential Duties
- Develop and maintain LLNL’s nuclear data infrastructure codes and APIs.
- Collaborate with LLNL transport code developers and nuclear data users to determine new features and priorities.
- Collaborate with teams of scientists and engineers and U.S. and international nuclear data communities.
- Pursue independent research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory.
- Publish research results in peer-reviewed scientific or technical journals and present results at external conferences, seminars and/or technical meetings.
- Mentor students and postdoctoral researchers.
