Job Description

Your responsibilities

Are you a recently-graduated scientist interested in contributing to scientific software, or a software engineer interested in the challenges offered by computing for High Energy Physics? Do you want to contribute to the software R&D at the heart of LHC data processing?

Join the EP-SFT group at CERN, responsible for developing and maintaining core software packages used by the experiments at the Large Hadron Collider, the world’s largest particle accelerator. You will become a core C++ software developer in the team developing the CernVM-FileSystem (CVMFS, https://cernvm.web.cern.ch/fs).

CVMFS is a global, read-only filesystem that specializes in delivering software and helps to enable distributed scientific computing across cloud- and supercomputing sites at a global scale.

In particular, you will:

• Improve the performance and usability of the CVMFS client and publisher
• Work with cloud- and supercomputing facilities to make CVMFS more accessible
• Contribute to the baseline support and maintenance tasks of the project.

Optional but a plus:

• Experience with container technologies (e.g. kubernetes, docker)
• Knowledge of the Go language
• Experience with writing networking code in C++
• Experience with HEP experiments code, their software lifecycle and build tools

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• By the application deadline, you have a maximum of two years of professional experience since graduation in STEM (or a related field) and your highest educational qualification is either a Bachelor’s or Master’s degree.
• 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.

Diversity has been an integral part of CERN’s mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
