Position Description:    

*** this position has been closed, and no new applications is accepted. ***

Berkeley Lab’s Physics Division has an opening for a DESI High-Performance Computing Developer to work on providing High-Performance Computing (HPC) support for the Dark Energy Spectroscopic Instrument (DESI) spectroscopic data processing pipeline, operations code, and scientific algorithms at the National Energy Research Scientific Computer Center (NERSC).  This work includes adapting codes to new NERSC architectures as they are deployed, improving workflow efficiency and scaling, and supporting technologies such as Docker.


What You Will Do:

  • Support operations of the spectroscopic data processing pipeline when running at scale at NERSC.

  • Participate in team collaboration with DESI scientists to support/advise when running at NERSC.

  • Support Docker/shifter-based workflow for scaling and long-term reproducibility.

  • Adapt DESI code to new NERSC architectures (e.g. GPUs).

  • Maintain DESI code when underlying OS and external packages are updated.

  • Profile and improve the efficiency of DESI spectroscopic pipeline and scientific algorithms.

  • Document code for both users and developers.

  • Write unit tests and integration tests in support of continuous integration testing at NERSC.

  • Participate in the development of research presentations for collaboration meetings, seminars, workshops, and conferences.

  • Report results to the supervisor and to the DESI collaboration working groups.

What is Required: 

  • Bachelor’s Degree in Physics, Astronomy, or closely related field and a minimum of 5 years of related technical experience in Physics, Astronomy, or Cosmology data or the equivalent combination of education and experience.

  • Experience with MPI programming on high-performance computing systems.

  • Experience with git version control, including branches and pull requests.

  • Proficiency in C++ and Python.

  • Proficiency in modern software development practices.

  • Excellent oral and written communication skills.

  • Ability to work effectively within a large geographically distributed collaboration with varying computational expertise.

What We Prefer: 

  • Ph.D. in Physics, Astronomy, Computer Science.

  • Experience working in the field of Astronomy, Cosmology, and Particle Physics Data.

  • Experience with the following:

    • Non-MPI multi-node parallelism (e.g. Dask, Hadoop, Apache Airflow, Spark).

    • GPU programming.

    • Docker, Singularity, or other software containers.

    • SQL databases (e.g. Postgres or MySQL).

  • Knowledge of astronomy/physics/cosmology datasets.


Berkeley Lab values a diverse workforce and culture of inclusion, which are keys to attracting and engaging the brightest minds to further our record of scientific excellence and groundbreaking innovations (https://diversity.lbl.gov). Applications from women, minorities, and other underrepresented groups are strongly encouraged.
