The Berkeley Lab is hiring a Computational Physicist to work in the PHAX group within the Scientific Data Division. The PHAX group excels in computational physics research and software development for next-generation physics experiments, including the LZ Dark Matter Experiment at Sanford Underground Research Facility.

This position will contribute to LZ software development, with opportunities for technical leadership and will participate in R&D efforts like the HEP Center for Computational Excellence (HEP-CCE). The Computational Physicist will propose new R&D projects in collaboration with computational physicists, data scientists, and software engineers in the LZ experiment, Scientific Data and Physics Divisions, ESnet, and NERSC.

What You Will Do:

  • Collaborate with computer scientists, physicists, and mathematicians at LBNL on high-energy particle physics software.
  • Support or upgrade the LZ data movement framework and enhance data infrastructure for bias mitigation.
  • Contribute to software R&D for next-generation HEP experiments.
  • Work with postdoctoral researchers and graduate students on related projects.
  • Possess excellent oral and written communication skills.
  • Demonstrated ability to work effectively in a cross-disciplinary team.
  • Resolve diverse problems requiring data analysis and evaluation of identifiable factors.
  • Exercise good judgment in selecting methods and techniques for solutions.

Additional Responsibilities as Needed:

  • Identify and contribute to LZ scientific projects requiring significant computing, developing new workflows.
  • Organize work in one or more LZ software areas.
  • Contribute to machine learning infrastructure and applications.
  • Propose new research projects aligned with group priorities.
  • Assist in coordinating efforts within LBL.

What is Required:

  • Requires 5 years of related experience with a Bachelor's degree, or 3 years with a Master's degree, or equivalent work experience.
  • Experience in scientific software development using C/C++ and Python.
  • Effective communicator and contributor to large software projects.
  • Proven ability to prepare and present research results.
  • Effective in cross-disciplinary teams.
  • Skilled in troubleshooting diverse problems through data analysis.
  • Experienced in networking with senior internal and external experts.

Desired Qualifications:

  • Experience with HEP software (Geant4, ROOT).
  • Experience with high-performance computing and software optimization.
  • Knowledge of parallel programming (CUDA, SYCL, HIP, Kokkos, OpenMP, OpenACC).
  • Familiarity with distributed computing (Ray, Dask, HPX).
  • Experience in machine learning applications and development.


  • 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.
  • The full salary range of the Computer Software Engineer 2 is between $106,596 to $179,880 annually and is expected to pay between a targeted range of $119,904 to $146,580 annually depending upon the candidate's skills, knowledge, and abilities, including education, certifications, and years of 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 may be performed on-site, hybrid, or full-time telework modes. Work must be performed within the United States.
