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.

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization.

This is your Quest. Deepen your knowledge and expertise faster than anywhere else on earth. Take Part!

Wouldn’t it be amazing to shape the way high energy physics analyses are done? Come join the ROOT https://root.cern team to combine your analysis experience with our expertise on processing data efficiently!

As the ROOT project we are providing the physicist’s tool for analyzing massive amounts of data. Its recent analysis interface (RDataFrame) is used by many physicists, and we want your help with growing RDataFrame and its user community. You will be working with other physicists doing an analysis with HEP experiments; you will determine and implement what’s missing in RDataFrame. You will be sharing your experience as a physicist with an agile, diverse team. We will guide you to transition into the more computing-centric world of a developer for scientific software.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State;
• You have a Master’s degree and between 2 and 6 years’ experience or PhD with up to 3 years of relevant experience in physics, computer science, or other related field;
• You should have a working knowledge of English or French.

Skills and/or knowledge:

• Experience with a PhD-level high energy physics analysis (even if not completed)
• Proficient in C++ and Python: you should know how to use templates and destructors; you should know Python data processing (could be any of Pandas, Numpy, or interfaces to Machine Learning libraries)

What we offer:

• An employment contract of in principle 24 months, with a possible extension up to 36 months;
• On-the-job and formal training at CERN as well as in-house language courses for English and/or French;
• A monthly stipend ranging between 6050 and 6650 Swiss Francs per month (net of tax);
• Coverage by CERN’s comprehensive health scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund;
• Depending on your individual circumstances: installation grant; family, child and infant allowances; payment of travel expenses at the beginning and end of contract;
• 30 days of paid leave per year.

How to Apply:

You will need the following documents to complete your application:

• A CV;
• A scanned PDF of your most recent relevant qualification;
• We recommend to add two recent letters of recommendation, giving an overview of your academic and/or professional achievements. You can upload these letters at the time of application if you have them to hand. You will also be provided with a link as soon as you have submitted your application to forward to your referees to upload their letters confidentially.

The earliest expected start date for selected candidates is May 2023.

Ready to take part? Then please submit your application by 23 January 2023 at  midnight (12.00 AM CEST).
