Applied Physicist in LAr Calorimeters (EP-ADE-CA-2025-251-GRAP)

Join the ATLAS experiment at the HL-LHC during a pivotal moment. In this role, you will help operate one of the world's most advanced calorimeter systems and shape the next-generation upgrade that will enable groundbreaking physics in the years ahead. You will work closely with experts developing, operating, and innovating the software and control systems that keep the detector running safely and efficiently. This position offers hands-on experience with large-scale data-acquisition systems, real-time control software, and detector operations in a high-energy physics environment.

Your responsibilities

You will:

• Develop and maintain detector control software using WinCC OA and OPC-UA;
• Deploy and operate high-voltage (HV) power modules for the calorimeter;
• Develop tools for configuring and monitoring the detector's front-end electronics;
• Support the integration, testing, and commissioning of new control systems for the Phase-II upgrade;
• Contribute to daily detector operations, troubleshooting, and monitoring improvements;
• This role includes team supervision responsibilities.

Your profile

Experience:

• Familiarity with Detector Control Systems;
• Familiarity with SCADA/WinCC and OPC-UA;
• Demonstrated experience in testing and operation of detector readout electronics and associated SW.

Skills:

• Knowledge about calorimeter detectors for high energy physics experiments;
• Rigorous and organised approach to work, producing quality results;
• Working well in teams, and presenting work to collaborators;
• Spoken and written English, with a commitment to learn French.

Eligibility criteria:

• You have a professional background in Physics or Applied Physics (or a related field) and have either:
  • a Master's degree with 2 to 6 years of post-graduation professional experience;
  • or a PhD with no more than 3 years of post-graduation professional experience.
• You have never had a CERN fellow or graduate contract before.
