The Computational Research Division at Berkeley Lab has an opening for an Algorithm and Software Designer/Engineer. The position will entail the implementation and documentation of algorithms and software infrastructure necessary to build adaptive algorithms for nonlinear partial differential equations in complex geometries on high-performance computing architectures, with a particular focus on performance on heterogeneous architectures and accelerators. The primary focus of this position will be implementing existing Chombo adaptive mesh refinement and mapped-grid algorithms for pre-exascale machines using the in-development Proto framework. Another focus will be on maintaining and extending the capabilities within the existing Chombo software framework, particularly with regard to the use of high-dimensional mapped-multiblock finite-volume discretizations. In addition, this position will also assist users inside ANAG, the greater Berkeley Lab community, and the international community in the use of ANAG software where appropriate.
What You Will Do:
Participate in the development of high-order finite volume methods on mapped multiblock grids, with applications to plasma physics and space science, using Proto, a C++ software framework for structured-grid and AMR methods.
Contribute in all phases of development, from the mathematics of algorithm design through software design, implementation, and testing, taking a role in moving projects through all of these phases.
Assist in the development and implementation of new application capability as needed.
Provide support with all requested assignments, including research, documentation of results and reporting results to colleagues in ANAG.
Support Chombo-based applications, in particular those involving mapped multiblock and adaptive mesh refinement, particularly with regard to performance on accelerators.
What is Required:
Bachelor's degree in Applied Mathematics, Computational Science, Engineering, Physics or a related discipline with a minimum of 5 years of related experience; or equivalent combination of education and experience with a strong background in computational methods and scientific computing.
Experience in high-order finite-volume numerical methods for solving PDEs.
Experience in mathematical software development, from algorithm design, through software design and implementation, to testing and deployment for application users.
Experience in block-structured adaptive mesh refinement algorithms.
Experience in high-performance parallel algorithms for partial differential equations.
Excellent verbal and written communication skills.
Experience analyzing data and evaluating identifiable factors.
M.S. or PhD in Applied Mathematics, Computational Science, Engineering, Physics or a related discipline.
This is a full-time 2 year, term appointment with the possibility of extension or conversion to Career appointment based upon satisfactory job performance, continuing availability of funds and ongoing operational needs.
This position will be hired at a level commensurate with the business needs and the skills, knowledge, and abilities of the successful candidate.
This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
Work will be primarily performed at Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.

About Lawrence Berkeley National Laboratory
In the world of science, Lawrence Berkeley National Laboratory (Berkeley Lab) is synonymous with excellence. Thirteen scientists associated with Berkeley Lab have won the Nobel Prize. Fifty-seven Lab scientists are members of the National Academy of Sciences (NAS), one of the highest honors for a scientist in the United States. Thirteen of our scientists have won the National Medal of Science, our nation's highest award for lifetime achievement in fields of scientific research. Eighteen of our engineers have been elected to the National Academy of Engineering, and three of our scientists have been elected into the Institute of Medicine. In addition, Berkeley Lab has trained thousands of university science and engineering students who are advancing technological innovations across the nation and around the world. Berkeley Lab is a member of the national laboratory system supported by the U.S. Department of Energy through its Office of Science. It is managed by the University of California (UC) and is charged with conducting unclassified research across a wide range of scientific disciplines. Located on a 200-acre site in the hills above the UC Berkeley campus that offers spectacular... views of the San Francisco Bay, Berkeley Lab employs approximately 4,200 scientists, engineers, support staff and students. Its budget for 2011 is $735 million, with an additional $101 million in funding from the American Recovery and Reinvestment Act, for a total of $836 million. A recent study estimates the Laboratory's overall economic impact through direct, indirect and induced spending on the nine counties that make up the San Francisco Bay Area to be nearly $700 million annually. The Lab was also responsible for creating 5,600 jobs locally and 12,000 nationally. The overall economic impact on the national economy is estimated at $1.6 billion a year. Technologies developed at Berkeley Lab have generated billions of dollars in revenues, and thousands of jobs. Savings as a result of Berkeley Lab developments in lighting and windows, and other energy-efficient technologies, have also been in the billions of dollars. Berkeley Lab was founded in 1931 by Ernest Orlando Lawrence, a UC Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It was Lawrence's belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab legacy that continues today.
