**Job Description**
As an Applied Physicist specializing in particle detectors, you will join the Experimental Physics (EP) department, specifically the CERN Detector Group of the ATLAS experiment.
* The Calorimeter section of the Detector Group has a leading role in the operation of the Liquid Argon (LAr) Calorimeter, the installation and commissioning of its Phase-II upgrade for HL-LHC as well as R&D activities for new calorimeter developments to be used in future accelerators.
You will be responsible for:
* The operation of the LAr calorimeter, especially its electronics, trigger electronics and associated software and firmware, for the remainder of Run-3.
* The on-site preparations for the Phase-II Upgrade of the LAr electronics at CERN as host lab and in the ATLAS cavern.
* The installation and commissioning of the LAr Calorimeter precision readout as well as the LAr Trigger electronics for Run-4.
Key Responsibilities:
* Take a leading role in the operation of the LAr calorimeter. This includes the supervision of a CERN-based team of technicians, students and scientists covering all aspects of the LAr calorimeter operation.
* Coordinate the efforts at CERN for all tests, including reception of deliverables and system tests, needed for the construction of the new LAr electronics for HL-LHC assisting the LAr community at large.
* Take a leading role in the preparations for installation and commissioning of the new LAr electronics on the ATLAS detector as well as prepare and lead a team to transition the current software and firmware integrated in the ATLAS environment to the one needed for the upgraded electronics.
* Contribute to the simulation, design and development efforts in the context of CERN's R&D activities related to Noble Liquid Calorimeters for future detectors.
Your Qualifications:
* PhD or equivalent relevant experience in the field of Physics, with specialization in particle detectors or a related field.
* Proven post-doctoral experience in the development and operation of particle physics detectors in general and calorimeters in particular.
* Experience with installing and commissioning new subdetector electronics and integrating a system within a particle collider experiment.
* Demonstrated experience with carrying out particle detector data analysis, especially in terms of detector operation and performance.
* Hands-on experience with hardware firmware and software for detectors, detector control and readout.
* Proven experience in coordinating multi-disciplinary teams of physicists, engineers and technicians.
* Demonstrated experience in developing data acquisition, data handling and analysis for detector and electronics tests.
**Technical Competencies:**
* Knowledge and application of calorimetry methods and techniques.
* Assembly and integration of detectors.
* Simulation, design and development of (parts of) detectors.
* Analysis and optimization of detector performance.
* Development of data acquisition, data handling and analysis for detector operation and readout.
**Behavioral Competencies:**
* Working in Teams: cooperating constructively with others in the pursuit of team goals; balancing personal goals with team goals.
* Achieving Results: driving work/projects along and seeing them through to their conclusion.
* Managing Self: demonstrating a receptive approach to feedback; being open to criticism and reconsidering position accordingly.
* Communicating Effectively: delivering presentations in a structured and clear way; adjusting style and content to the audience.
* Solving Problems: assimilating large quantities of information, identifying key issues and formulating conclusions clearly and concisely.
**Language skills:**
Spoken and written English: ability to understand and speak in professional contexts.
Ability to draw up technical specifications and/or scientific reports and to make oral presentations.
Ability to understand and speak, or willingness to learn and improve French.
