What you’ll do

During Long Shutdown 3 (LS3, 2026-2030), the ATLAS detector will be upgraded with new detector systems, requiring detailed engineering work to finalise their design, integration, installation sequence, and connection to services. This will involve substantial on-site activities. As a mechanical engineer, you will join the TC engineering team and serve as the interface between ATLAS Technical Coordination (TC) and the detector upgrade teams, particularly for critical mechanical integration activities.

Your responsibilities

• Oversee the design of all mechanical aspects of a detector system, in collaboration with the worldwide institutes contributing to the production of deliverables.
• Define and manage the mechanical interfaces between the ATLAS detector and its infrastructure, including supports and services. Supervise the production of 3D integration models and ensure that the relevant envelopes are properly taken into account.
• Develop the transport and underground installation sequence, and design the associated installation tooling and its interfaces with the detectors.
• Support the detector team in coordinating the production of mechanical components to help ensure their timely delivery and facilitate smooth assembly planning.
