Are you an experienced software developer, or a scientist with a masters degree or PhD interested in the challenges offered by computing for scientific fields such as High Energy Physics (HEP)? Do you want to contribute to the software R&D at the heart of LHC data processing and analysis?
Join the EP-SFT group at CERN, responsible for developing and maintaining core software packages used by the LHC experiments and the HEP community at large. You will become a core C++ and Python software developer in the ROOT team (https://root.cern).
In particular, you will:
- Enhance the integration and interoperability of Python and C++ codebases, with a focus on the interaction between the Python interpreter and the C++ interpreter cling (https://cling.readthedocs.io).
- Improve the design of Python interfaces to interact with C++ libraries as commonly done in scientific, performance-oriented Python packages.
- Evolve, simplify and streamline the ROOT plotting interface with a user-centric perspective and result-oriented R&D.
- Contribute to the baseline support and maintenance tasks of the project.
About CERN
At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on home.cern.
Diversity has been an integral part of CERN's mission since its foundation and is an establish... continue reading
