Software Integration Engineer (EP-AIP-SDS-2024-28-GRAE)

Your responsibilities

ALICE (A Large Ion Collider Experiment), is a dedicated heavy ion experiment at the Large Hadron Collider (LHC). The ALICE Collaboration is studying the physics of strongly interacting matter at extreme energy densities and temperatures. Since the restart of the Large Hadron Collider in 2021, ALICE operated up to a peak Pb-Pb collision rate of 50 kHz. This resulted in more than 100 PB so far.

The EP-AIP-SDS section at CERN is responsible to deliver high quality reconstruction, simulation and analysis software to the experiment in order to work with such data. We utilise a Continuous Integration system to guarantee the smooth functioning and progress of the experiment’s Software and Computing infrastructure. This system constantly oversees the entire development procedure, starting from the introduction of a new feature, through testing it, and finally integrating it into periodic releases that are subsequently rolled out on the GRID.

With hundreds of developers contributing to the code base, this process is in particular essential to assure fast and correct turn around of simulation, reconstruction and analysis production requests, adapting to the physics needs of the experiment and ensuring optimal resources usage. The selected candidate will be in charge of maintaining and further developing the ALICE Continuous Integration infrastructure and the associated tools, with a continuous effort to reduce test turnaround time and to assure highest quality and performance of the regular software releases. Experience with managing a cluster of computers, build tools and best practices on Linux and MacOSX is considered an important asset.

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.
