The experimental particle physics group at the University of California, Irvine invites applications for a Project Scientist and/or Specialist position to work on the ATLAS experiment at the CERN Large Hadron Collider.

UCI group, consisting of Profs. Anyes Taffard, Andrew Lankford and Daniel Whiteson, has been a member of the ATLAS collaboration at the Large Hadron Collider (LHC) since 1994 and is actively involved in the Muon Spectrometer readout electronics, the Trigger and Data Acquisition Systems, and Software and Computing.
The candidate is expected to contribute to the evolution of ATLAS offline software to run efficiently on LCF class machines and to ATLAS software and performance monitoring. The work involves participation in development of ATLAS simulation, digitization and reconstruction components of ATLAS software to enable efficient utilization of HPCs and accelerator, as well as exploiting Machine Learning which can provide both training and inference use cases for such resources.

Qualifications and Essential Job Functions:
• Bachelor’s Degree or above in Computer Engineering (BSCE, MSCE or PhD CE) or in Physics (BS/BSc, MS or PhD Physics).
o Ph.D. degree 0-1 year of experience or equivalent; MS degree and 3-4 years of experience or equivalent; BS degree and 6-8 years of experience or equivalent.
• At least 2 years working with high-energy physics offline software (simulation, digitization and reconstruction).
• Experience with:
o Fluency in C++, Python, Bash scripting
o ROOT, Valgrind, KCacheGrind, GNU project debugger (gdb), CMake, Docker, Singularity, Linux
o High performance computing and scientific code development
o Parallel programing (OpenMP) is desirable.
o Modern machine learning and GPU is preferable.
o ATLAS Gaudi/Athena is preferable
• Demonstrated ability to plan and carry out independent research and project leadership.
• Solid communication skills, both verbal and written, as well as outstanding skills in developing working relations with others.

• Salary is commensurate with experience.
• The appointment will be made either as a Specialist or Project Scientist depending on the candidate qualifications.
• The initial contract is one-year, renewable upon satisfactory job performance and continuing availability of funds.
• Work will be primarily performed at CERN and will require travel to UCI as well as travel to institutions with whom we collaborate.
