This position will be hired at a level commensurate with the business needs; and skills, knowledge, and abilities of the successful candidate.
What you will do:
Work closely with one of more ECP application development teams through the NERSC NESAP program to help optimize their code to run well on future HPC systems. Collaborate with other stakeholders like HPC technology vendors and library developers in the optimization process.
Educate and train ECP users by creating content for the NERSC website with online tutorials and documentation, giving presentations, and attending conferences.
Keep abreast of developments and research in the high-performance computing field, particularly within ECP, including algorithms, programming-models, tools and optimization strategies.
Serve as a NERSC mentor for one or more postdoctoral fellows in application performance on ECP applications.
Additional Responsibilities as needed:
Travel may be required.
Bachelor's degree in a scientific field or computer science with a minimum of 8 years of related experience or 6 years and Master's degree or equivalent experience.
At least 4 years' experience programming and running codes in an HPC environment.
Experience writing web documentation and tutorials and teaching and developing workshops in technical computing areas.
Broad computational background, including knowledge of Unix, (Fortran, C, or C++), optimizing applications for accelerators or other energy efficient architectures as well as knowledge of HPC algorithms, programming models, profilers, debuggers, and performance tools.
An ability to work effectively with users, understand user requirements, communicate well orally and in writing and show initiative, tact, and judgment in developing solutions for users.
Excellent problem solving and communication skills.
Exascale programming techniques (e.g. accelerators and other energy-efficient architectures), distributed-memory and on-node parallel programming, MPI, OpenMP, CUDA, OpenACC, Fortran, C, C++, shell scripting, python, UNIX/LINUX, parallel code debugging, profiling and optimization, code porting, code scaling, and performance analysis.
Additional Desired Qualifications:
Advanced degree preferred.
Experience optimizing applications for energy-efficient accelerator architectures.
Extensive use or design of HPC profiling or optimization tools.
Advanced knowledge and experience with HPC computing/data architectures
Software engineering expertise
Filesystems and IO optimization experience
Recognition in the HPC community at the national level
Involvement in one or more strategic initiatives at the Federal level (e.g. DOE Exascale Initiative, SciDAC projects, etc).
The posting shall remain open until the position is filled, however for full consideration, please apply by close of business on August 23, 2018.
This is a full time, 2 years, 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.

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.
