Within the Experimental Physics Department (EP), in the Software Development for Experiment Group (SFT), you will be responsible for maintaining, developing, and validating different software stacks to be used to build software ecosystems for physics experiments. You will be involved in an ongoing programme aimed at extending commonality of software ecosystems, and work on new developments to improve computing performance.

You will join the Stacks team, responsible for maintaining and developing software stacks used by the Large Hadron Collider (LHC) experiments and the broader particle physics community, including those investigating the potential of future projects. The team builds on the experience gained during the first three LHC runs and adapts software builds to architectural properties to enhance computing performance.

Stacks offers coherent software that meets the needs of LHC experiments, following an iterative approach, working in close contact with users. The built stacks include a large number of packages covering a wide range of needs and are distributed on the CernVM File System, which automatically tracks versions and provides time-machine functionality that can be effectively used for software preservation.
