Research Software Engineer

at  Lawrence Berkeley National Laboratory

Lawrence Berkeley National Lab’s (LBNL) Accelerator Technology & Applied Physics Division (ATAP) has an opening for a Research Software Engineer to join the Superconducting Magnet Program (SMP) team.
In this role, you will be responsible for the design, development, testing and maintenance of advanced computer simulation codes to support the development of superconducting magnets, and in particular high-temperature superconducting magnets. Working within the ATAP’s Superconducting Magnet Program and the Berkeley Center for Magnet Technology (BCMT) as a vital member of a team consisting of physicists, engineers, fabrication teams, post-doctoral scholars, and students. This encompasses the development and analysis of novel computational methods based on Finite Elements, as well as the development, modification and implementation of new and existing software/simulation codes using other techniques such as network-models, on desktop and supercomputers.
The position also includes participation in research, ensuring technical success of simulation campaigns, code maintenance (bug triage, supercomputer environments, build system, dependencies, deployment and automation), user support, testing and benchmarking, collaboration with physicists and engineers within SMP and BCMT, and reporting of results in scientific presentations and/or literature.

DESIRED QUALIFICATIONS:

• Ph.D. in Applied Mathematics, Physics, Computational Science, Mechanical Engineering or related field plus postdoctoral research experience preferred.
• Demonstrated expertise in C++ and Python for scientific computing.
• Demonstrated expertise in parallel, High-Performance Computing (MPI, OpenMP) and GPU programming.
• Knowledge of electromagnetics, mechanics, thermal, and hydraulic processes, the mathematical modeling of those processes, and associated numerical solution techniques.
