Electronics/Electrical Technician Power Converter Systems (SY-EPC-2026-111-LD)

These positions offer the opportunity to work in different technical teams within the group, contributing to a wide range of activities including: Installation, testing and commissioning of power converter systems. Deployment and configuration of controls electronics and infrastructure. Renovation and upgrade of converter control systems. Development and validation of electronic and control interfaces. Operational support, maintenance and troubleshooting in the field. Depending on your profile, skills and interests, you may join one of several specialised teams working on: High-power converter installations for accelerator magnets. Converter controls electronics and infrastructure deployment. Modern Switch-mode converter and conventional thyristor systems. Static Var Compensator (SVC) modernisation. Configuration, controls integration and commissioning activities during CERN’s Long Shutdown 3 (LS3). As an Electronics/Electrical Technician within the Power Converter Group, you will contribute to the deployment, operation and maintenance of CERN’s accelerator power systems and controls infrastructure. Depending on the assignment and team, your responsibilities may include: Participate in the installation, testing, commissioning and maintenance of power converter systems ranging from 10 kW to several tens of MW. Contribute to the upgrade and renovation of converter control electronics and infrastructure. Adapt electrical schematics and associated bills of materials for integrating the standard Control Electronics platform of EPC group into Thyristor converters. Participate in the design and validation of electronic boards and low-level interfaces using analogue and digital electronics. Assemble, test and install electronic crates, racks and cabinets. Contribute to fault-finding, corrective interventions and operational support activities. Coordinate and supervise controls infrastructure installation activities in the field. Validate technical requirements together with equipment owners and users, acting as an interface between technical experts, central services and industrial support teams. Prepare and organise work activities and follow implementation schedules. Oversee and verify the work of service providers for networking, cabling, optical fibres and rack installations. Ensure compliance with CERN safety rules and documentation procedures. Deploy and configure converters controllers and associated controls infrastructure using dedicated software tools. Participate in commissioning campaigns during accelerator shutdowns and operational periods. Contribute to continuous improvement and modernisation projects. Ensure clear reporting and technical documentation of activities.

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. CERN’s Electrical Power Converter Group is recruiting electronics/electrical technicians to contribute to major modernisation, consolidation and infrastructure projects linked to CERN’s accelerator complex. You will work closely with engineers, technicians, industrial support teams and CERN’s central services in a highly collaborative and international environment.
