Résumé du poste

CERN ATLAS ITk Integration team seeks an Applied Physicist or Engineer to lead the testing and integration of silicon ITk structures across sites, collaborating with DESY/NIKHEF to synchronize testing and support integration teams for SR1 procedures and cavern commissioning.

The role requires a Master’s or PhD in Applied Physics or Engineering, hands-on testing experience, and strong teamwork. This is an onsite, four-year contract role at CERN with extensive field work.

Qualifications

• Proven experience in the integration, testing and operation of silicon detectors for high energy physics experiments.

Responsabilités

• Testing and verification of integrated ITk Strip Barrel and Endcap structures and services in the surface integration facility (SR1) at CERN.
• Work closely with integration sites off CERN, e.g. DESY or NIKHEF, synchronise the testing and provide trouble shooting support for integration teams including support at the sites.
• Develop software and hardware elements for the integration testing of ITk Barrel and Endcaps in the various integration sites and validate the procedures in SR1.
• Streamline and document procedures for ITk integration testing and service validation and extend the testing procedures for the ITk Detector after installation and during commissioning.
• Participate hands-on in the ITk Detector integration work in the ATLAS SR1 cleanroom and during ITk installation in the cavern including the preparation of equipment in the cavern.

Description du poste

Applied Physicist/Engineer - ATLAS ITk Integration (EP-ATL-TRK-2026-207-LD)

• Contract
• Compensation: from CHF 9,236 - monthly

At CERN , the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature.

Introduction

The CERN ATLAS Team plays a major role in the construction and integration of the future silicon ATLAS Inner Tracker (ITk). The different parts of the ITk system are being constructed and integrated in institutes and then transported to CERN where the entire ITk will be assembled.
As an applied physicist or engineer in the CERN-ATL Team, you will join the Tracker section (EP-ATL-TRK) and work closely with the teams in the different institutes to synchronise the integration testing of the ATLAS ITk parts on surface, support their integration and commissioning into the ATLAS ITk and prepare the cavern commissioning.

Functions

• Testing and verification of integrated ITk Strip Barrel and Endcap structures and services in the surface integration facility (SR1) at CERN.
• Work closely with integration sites off CERN, e.g. DESY or NIKHEF, synchronise the testing and provide trouble shooting support for integration teams including support at the sites.
• Develop software and hardware elements for the integration testing of ITk Barrel and Endcaps in the various integration sites and validate the procedures in SR1.
• Streamline and document procedures for ITk integration testing and service validation and extend the testing procedures for the ITk Detector after installation and during commissioning.
• Participate hands-on in the ITk Detector integration work in the ATLAS SR1 cleanroom and during ITk installation in the cavern including the preparation of equipment in the cavern.

Master's degree or PhD or equivalent relevant experience in the field of Applied Physicist or Engineering or a related field.

Experience

• Proven experience in the integration, testing and operation of silicon detectors for high energy physics experiments.
• Proven experience in integration and commissioning of silicon trackers including services validation.
• Demonstrated experience in the development of DAQ/online software or detector control systems for silicon detectors in high energy physics experiments.
• Demonstrated experience in developing and streamlining testing procedures.
• Demonstrated experience in integration and commissioning of silicon trackers including services validation.

The following experience would be an advantage:

• Previous work on particle detector operation in an experiment.
• Assembly of sensitive equipment in a clean room environment.
• Testing and validation of detector, accelerator and beam line components.
• Assembly and integration of detectors.
• Construction, test and installation of electromechanical equipment and systems.
• Development of application software.
• Assembly and integration of infrastructure for detectors or experimental facilities.
• Achieving Results: delivering high quality work on time and fulfilling expectations.
• Demonstrating Flexibility: adapting quickly and resourcefully to shifting priorities and requirements.
• Working in Teams: building and maintaining constructive and effective work relationships.
• Managing Self: working well autonomously; taking on activities and tasks without prompting.
• Communicating Effectively: expressing opinions, ideas and suggestions with conviction and in a logical/structured manner; keeping to the point.

Spoken and written English, with a commitment to learn French.
