Software Engineer in the CERN Physics Department (EP), Software for Experiments Group (SFT).


The LHC experiments are collaborating closely in order to make the changes required to improve the performance of their data processing software in preparation for the HL-LHC upgrade. The many common software packages require collective efforts which need to be coordinated across the experiments and across laboratories.


The HEP Software Foundation (HSF) [] has been created as an umbrella organization to facilitate the coordination and common efforts in HEP software and computing internationally. The main objectives are to share expertise, raise awareness of existing software and solutions, catalyse new common projects and promote commonality, training and support for project teams wanting to contribute to the common goals. In addition, the foundation should support the career development for software and computing specialists, provide a framework for attracting effort and support to software and computing common projects as well as to provide a structure to set priorities and goals for the work. 



The successful candidate will play a major role in fostering new common software activities and in building new collaborative efforts. The role also involves taking up responsibilities for the implementation of services that can be of general use to the community, in particular by adopting guidelines and tools for supporting all phases of the software development life-cycle.


Specific duties will be to:


  • Manage HSF information;
  • Update and curate the knowledge base of HEP software;
  • Collect and homogenise training material;
  • Provide services for software integration, validation and distribution;
  • Helping developers to integrate their software packages into the overall HSF software ecosystem;
  • Contribute directly in development tasks associated with one or more of the common software projects that the HSF supports.


Qualification required

PhD / Doctorate in the field of experimental physics or computing science, or equivalent.


Experience and competencies

The experience required for this post is:
