ISOLDE System Engineer (SY-STI-TSP-2026-131-GRAP)

The STI group develops technologies that enable particle beam production and studies how particle beams interact with materials. Its work supports a wide range of activities, from advanced beam technologies to the development of radioactive ion beams for nuclear and particle physics research.

In this role, you will contribute to the upgrade of the ISOLDE Offline Facilities, which are used to develop and test new beam production and manipulation systems before deployment on the accelerator. Working with engineers and physicists, you will coordinate technical activities, support installation and commissioning, and help deliver reliable infrastructure for future radioactive ion beam experiments.

Your responsibilities

• Lead the technical coordination and day-to-day management of the ISOLDE Offline Facilities consolidation project.
• Coordinate activities between different internal technical services and teams.
• Follow project schedules, technical interfaces, procurement activities and installation planning.
• Organise technical meetings, track actions and communicate project progress to stakeholders.
• Ensure compliance with CERN safety regulations.
• Participate in the preparation of technical specifications, installation documentation and project reports.
• Support the integration and commissioning of upgraded beam delivery and target production infrastructure.
• Contribute to system testing and acceptance.
• Work closely with physicists, engineers and technicians to ensure successful project delivery.
• Participate in the commissioning of upgraded systems.
