This position will be hired at a level 3 or 4 contingent upon level of experience, skills, knowledge, and abilities of the successful candidate.
What You Will Do:
Contribute to benchmarking and research activities at NERSC as part of the ATG group.
Measure and analyze the performance and parallel scalability of key scientific applications that comprise NERSC's evolving workload on current and future high performance computing (HPC) platforms using a hierarchy of benchmark programs; this requires porting and building complex applications on a variety of different operating systems and hardware.
Profile the applications to identify architectural and algorithmic bottlenecks with a particular emphasis on emerging emerging technologies and paradigms.
Propose remedies to the identified bottlenecks via software restructuring and/or architectural improvement with comprehensive understanding of any trade-offs in design, cost, and software engineering effects. Assess emerging technologies in architecture, algorithms, parallel programming paradigms, and languages to provide input for HPC system procurements.
Prepare timely reports, papers, and lectures describing significant results for dissemination within NERSC and throughout the broader HPC research community.
Take a lead role in at least one of the activities described above, take responsibility for complex problems, have frequent interactions with NERSC users to provide technical expertise and will be expected to share results with the broader HPC community by participating in conferences.
Produce LBNL technical reports and formal papers to document results.
What is Required:
Bachelor of Science degree in Computer Science, Computational Science, Computer Architecture, Physical or Biological sciences or equivalent experience and a minimum of eight years experience in HPC.
Detailed understanding of state-of-the-art tools used to program, profile, and debug parallel scientific applications. (Such as MPI, PGAS, OpenMP, and hybrid-parallel codes using C, C++, and Fortran 77/90 code.)
Experience in benchmarking, code instrumentation, and performance analysis of parallel applications with emphasis on emerging architectures. Experience with performance profiling tools, hardware performance counters (e.g. Intel Vtune, Cray PAT, or PAPI), and/or code instrumentation systems like Tau.
Experience with construction, porting and/or analysis of large-scale scientific applications to a variety of parallel HPC platforms.
Proven record of working effectively in a team, seeing projects through to completion, meeting deadlines, interacting with users, and thorough documentation of contributions.
Experience with computer architecture trends and their application to High Performance Computing (HPC).
A demonstrated ability to lead technical efforts in a team environment.
Demonstrated track record of research and technical publications. Ability to write and present technical papers at conferences and other venues to disseminate research work.
Excellent written and oral communication skills.
Additional Desired Qualifications:
Experience with the use of script languages and system utilities such as configure, Perl, UNIX shell scripts, and "make."
The posting shall remain open until the position is filled, however for full consideration, please apply by close of business on September 3, 2018.
This is a full time career appointment.
Full-time, M-F, exempt (monthly paid) from overtime pay.
Salary is commensurate with experience.
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.
