Software Developer 3 - 75561
Organization:  ES-Earth Sciences

The Earth Sciences and Computational Research Divisions at the Lawrence 
Berkeley National Laboratory invite applications for a Software Developer to 
support computational research in climate change science at LBNL.  The 
successful applicant will be able to work as an independent developer and as a 
member of a collaborative team to convert mathematical representations of 
climate processes into highly parallel code, implement these representations in 
the latest generation of the Community Earth System Model (CESM), and conduct 
numerical experiments with the CESM in collaboration with the Climate Sciences 
Department.  We are seeking individuals who are interested in both the 
climatological and computational science required to advance our capabilities 
to understand and predict the Earth's environmental future using advanced 
petascale computing systems.

Key Responsibilities:
• Design, implement, test and maintain new scientific functionality for 
regional and global Earth System models.
• Collaborate with scientists, students, and professors on new applications of 
the models (such as data assimilation) and on the scientific extension of the 
climate models.
• Work with remote software engineering groups to incorporate these extensions 
into public-domain climate models used by the worldwide scientific community.
• Participate in the team's iterative software engineering approach, and 
contribute to project and task planning.
• Participate in ad hoc analysis tasks to reduce and catalog data sets from the 
numerical experiments using latest HPC analysis and provenance tools

Additional Responsibilities:
• Supervise the execution of model experiments and archival of data and output, 
as well as visualization, and post-processing of model results on local and 
remote clusters and supercomputers.
• Validate the CESM model on the latest machines at the National Energy 
Research Supercomputing Center (NERSC), troubleshoot and fix problems in the 
climate models and their run-time environment.
• Assist in proposal development for NERSC and other high-resolution computing 
systems and monitor resource usage.

• Advanced degrees in computer science, mathematics, applied mathematics, 
software engineering, computer programming, data structures, atmospheric 
science, physics, applied mathematics or related technical fields.
• Ability to work independently as well as collaboratively in interdisciplinary 
• Interest in contributing to an active intellectual environment.

Desirable Qualifications:
• Ph.D. in Applied Math
• Advanced studies in large scale scientific computing, compilers, physics, 
chemistry, and other sciences
• Development and/or application of climate models; experience in climate data 
analysis and statistical analysis
