Mechanical Engineer - ATLAS ITk Pixel Detector (EP-DT-EO-2026-222-LD)

Introduction The CERN ATLAS Team plays a major role in the construction of the future silicon ATLAS Inner Tracker (ITk). In particular, the CERN Detector Technologies (DT) team focuses on the realisation of the Pixel Outer Barrel for the ITk. Our activities include the design, prototyping and assembly of the support structures and tooling as well as the final detector integration, installation and testing. As a mechanical engineer in the CERN-DT Team, you will join the Engineering Office Section (EP-DT-EO) and work closely with personnel from the ATLAS Group (EP-ATL) and the Technical Coordination Team of the ATLAS Experiment on the design, construction and installation of the ATLAS ITk Pixel Outer System. Functions - Design of precision tooling for the integration, testing and installation of the ITk Pixel Outer System Detector, comprising the Outer Barrel, Endcaps and Inner System Support Tube. - Design and develop service installation procedures and tooling, including temporary service management solutions for testing of the ITk Pixel Detector. - Verify the design of components and tooling according to the relevant standards and best engineering practices, performing both, analytical and numerical calculations. - Develop, document and implement tools and procedures for integration and installation of detector components and services. - Participate hands-on in the detector integration work in the ATLAS SR1 cleanroom as well as the preparation on surface and in the cavern for the installation. - Prepare technical specifications for components and tools, following up their production, acceptance and installation. - Support preparation of and participate in the ATLAS ID detector extraction. 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.
