Berkeley Lab’s National Energy Research Scientific Computing Center (NERSC) is looking for an exceptional and motivated Application Performance Specialist to join the Application Performance Group to help prepare large-scale scientific codes for next-generation high performance computing (HPC) systems at the center. The Application Performance Specialist will be responsible for managing deep engagements with users and strategic projects around application performance profiling and analysis, debugging and optimization. Consultants in APG are also part of a team that is responsible for creating and maintaining web documentation and training programs for all NERSC users.


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 two or more 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.

  • Help the general NERSC user community port and develop codes that will run well on exascale-like architectures (accelerators and other energy-efficient architectures).

  • Provide a broad spectrum of expert and courteous consulting services to users. Develop solutions for user problems and provide one-on-one assistance as needed. Manage and solve complex problems in a timely courteous manner consistent. Convey user feedback and concerns to other NERSC staff

  • Educate and train 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, including algorithms, programming-models, tools and optimization strategies.

  • Participate in the design and running of benchmarks and other tests to evaluate new HPC technologies and ensure that NERSC systems and software are operating correctly.

  • Provide input and assistance in the procurement of new systems.


Additional Responsibilities as needed:

  • Travel may be required.


Required Qualifications:

  • 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 four years’ experience programming and running codes in an HPC environment.

  • 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.

  • Experience writing web documentation and tutorials and teaching and developing workshops in technical computing areas.

  • 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.

  • Strong project management and analysis skills, and a demonstrated ability to lead technical efforts with teams of people across different groups.

  • Demonstrated ability to mentor students, interns, and postdoctoral researchers.


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.

  • Web programming.

  • 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.

Notes:

  • 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.
