Job Description
Your responsibilities
Are you a physicist or data scientist specialising in software development or a software engineer interested in data science and physics? Do you like to craft robust and performant software components at the heart of large scientific software stacks? Do you enjoy taking full advantage of multicore and heterogeneous platforms?
Join the ROOT team (https://root.cern) to become a core developer on ROOT math tools on heterogeneous platforms in the context of the CERN Experimental Physics Department R&D programme (EP R&D), working at the heart of the LHC Run 3 data taking campaign, the preparation for the future High Luminosity LHC (HL-LHC) and beyond!
In particular, you will:
- Prototype the full analysis of particle physics datasets on the GPU within the ROOT framework.
- To that end, implement typical data reduction like histogramming for multicore CPUs and hardware accelerators such as GPUs.
- Implement highly-ergonomic user interfaces for hardware-accelerated ROOT functionality, for both C++ and Python applications.
- Embed your developments in the ROOT analysis tools (e.g. RDataFrame and RooFit) and propose integration strategies to the LHC experiments, for example in the area of data quality monitoring.
- Take part in the baseline support, modernization and maintenance tasks of the ROOT project.
Your profile
Skills and/or knowledge
The following list (in order of priority) characterises the ideal candidate:
- C++ (C++17 and onwards, STL data structures and algorithms)
- Parallel, heterogeneous programming: multithreading concepts and tools (e.g. TBB) GPU programming (e.g. CUDA)
- Statistical treatment of data distributions
- Python (software development with Python 3) Optional, but considered a plus:
- ROOT
- HEP experiments, their data lifecycle and workflows (especially in the data quality monitoring)
Eligibility criteria:
- You are a national of a CERN Member or Associate Member State.
- You have a professional background in STEM (or a related field) and have either:
- a Master's degree with 2 to 6 years of post-graduation professional experience;
- or a PhD with no more than 3 years of post-graduation professional experience.
- You have never had a CERN fellow or graduate contract before.

About us
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 http://home.cern.
We are on a Quest. A Journey into discovery like no other. Bring your expertise to our unique work and develop your knowledge and skills at pace. Join world-class subject matter experts on unique projects, in a Quest for greater knowledge and deeper understanding.
