As a Detector Safety Physicist, you will be part of a multidisciplinary team responsible for the Detector Safety System (DSS) of the ATLAS experiment. You will lead upgrade, commissioning, and definition of safety systems for new ATLAS sub-detectors and contribute to infrastructure upgrades for Run 4 operation.

Responsibilities

  • Lead the Detector Safety System (DSS) testing and commissioning activities with different sub-systems.
  • Monitor the installation of cables used for signals exchanged between the DSS and the different sub-systems.
  • Design safety matrices for new sub-systems in collaboration with safety and detector experts.
  • Improve monitoring systems in the ATLAS galleries, including water leak detection systems.
  • Upgrade central infrastructure components in the ATLAS galleries.
  • Participate in the regular maintenance of fire, evacuation, gas, and Oxygen Deficiency Hazard (ODH) safety systems.
  • Follow up on and present the progress of work carried out by the DSS team to the ATLAS Safety and Technical Coordination teams.
  • This role includes team supervision responsibilities.

Requirements

  • You must be a national of a CERN Member State or Associate Member State, excluding Pakistani, Lithuanian, Latvian, Cypriot and Croatian nationals due to Associate Membership Agreement limits.
  • By the application deadline, you must have a master’s degree with 2 to 6 years of professional experience since graduation or a PhD with a maximum of 3 years of professional experience since graduation.
  • You are not eligible with only a bachelor’s degree.
  • You must never have had a CERN fellow or graduate contract before.
  • Experience with safety system chains, including analogue and digital sensors, alarms, and interlocks.
  • Experience in the wiring and testing of Programmable Logic Controller (PLC) systems.
  • Knowledge of industrial communication protocols, such as I²C and SPI.
  • Experience with electrical and thermal matching of components to circuit board requirements.
  • Experience in the development, manufacturing, and assembly of electronic boards.
  • Experience operating detector systems in a large-scale collaborative environment.
  • Your studies focused on Applied Physics.
  • Ability to follow procedures and remain calm in stressful situations.
  • Strong teamwork skills, with the ability to work effectively in multidisciplinary teams of scientists and engineers.
  • Familiarity with WinCC OA or similar SCADA systems, as well as OPC UA servers.
  • Strong verbal and written communication skills to convey research findings clearly.
  • Practical knowledge of Python software development would be an advantage.
  • Spoken and written English, with a commitment to learn French.
