Software Engineer in the Beams Department (BE), Controls Group (CO), Data Services Section (DS).

You will join:

  • The BE Department, responsible for the beam generation, acceleration, diagnostics, controls and performance optimization for the LHC and its injector accelerators.
  • The CO Group, responsible for providing and supporting the controls infrastructure used to operate and maintain these particle accelerators 24 hours a day.

As a Software Engineer in the DS Section, you will initially join the team behind the CERN-wide Layout Service - providing the system for managing the data that describes the functional layouts of CERN's accelerators and supporting installations, and tracks their evolution over time.  In this team you will take a major role in the development of a new system aimed at allowing experts from around CERN to consult and manage the layout data which is used by approximately 40 other systems at CERN.  In particular you will:

  • Participate in the whole software development lifecycle (requirements, design, development, testing), following a modern agile approach.
  • Communicate with the end-users of the services to understand their needs and help translate these into appropriate software solutions.
  • Interact with skilled and motivated software engineers on a daily basis to deliver quality results.
