Job Description
Your responsibilities
Are you a Scientist specialising in Software Development or a Software Engineer interested in Physics? Do you like intuitive, simple and powerful interfaces? Do you want to contribute to the software R&D at the heart of LHC data processing and analysis?
Join the ROOT team (https://root.cern) to become a Core Developer on ROOT data analysis and visualisation tools!
In particular, you will:
- Enhance the Python and C++ interoperability in ROOT via PyROOT, the HEP's entrance to all C++ from Python through the automatic and dynamic creation of bindings.
- Evolve, simplify and streamline the ROOT plotting interface with a user-centric perspective and result-oriented R&D.
- Improve the usability and ergonomic design of the Python interfaces of ROOT's C++ analysis tools such as histograms, graphs or RDataFrame declarative and parallelized analysis.
- Contribute to the baseline support and maintenance tasks of the project.
Your profile
Skills and/or knowledge
The following list (in order of priority) characterises the ideal candidate:

- C++ (STL interfaces and algorithms, template metaprogramming, C++17 and onwards).
- Visualization tools (e.g. matplotlib, seaborn), interactive analysis environments (e.g. JupyterLab) and plugins to integrate interactive visualisations in a notebook.
Optional but a plus:
- Distributed computing environments and Python tools to drive distributed applications (e.g. Dask, PySpark, Ray).
- ROOT.
- Statistics and statistical treatment of data distributions.
- HEP experiments, data lifecycle and analysis workflows.
Eligibility criteria:
