Mechanical Engineer ATLAS ITk Pixel EP-ATL-TRK-2026-157-GRAE

Participating in the conception, detailed design, production, testing, and installation of detector components, assembly tooling, and test infrastructure for the ITk Pixel Outer Barrel. Developing, documenting, and implementing procedures for the assembly, testing, installation, and repair of detector components and sub-assemblies. Managing the procurement of materials, detector components, and tooling, including follow-up on acceptance and installation. Contributing hands-on to the production and quality control of detector components, including OB local supports, global structures, cooling pipe extensions, and detector sub-assemblies (e.g. inclined units).

At CERN, the European Organization for Nuclear Research, we are pushing the frontiers of science and technology. Our groundbreaking work brings together not only physicists but also a diverse range of professionals from engineering, technical, scientific, and administrative fields. Together, we foster an environment where innovation and collaboration thrive. Every day, we face exciting new challenges and opportunities to contribute to cutting-edge research that shapes our understanding of the universe. We meet these challenges through the diverse perspectives within our teams, ensuring every contribution is valued and driving our shared sense of inclusion and purpose. Diversity is a core value of CERN since its foundation, and it remains central to our mission and continued success. If you are ready to be part of a dynamic, inclusive community pushing the boundaries of knowledge, CERN is the place where your curiosity and skills can thrive. Be part of our mission to uncover what lies at the heart of the universe!
