What you'll do

Are you a motivated Mechatronics Engineer ready to support the development and operation of motion and sensing systems for Beam Intercepting Devices (BIDs) across CERN’s accelerator facilities? This role bridges operational support and R&D, focusing on sensor evaluation, experimental instrumentation, and motion system development. You will contribute to the performance, reliability, and precision of critical accelerator components by integrating mechatronic and software control aspects into robust, maintainable systems.

Your responsibilities

• Develop, test, and maintain motion and sensing systems used for the control of Beam Intercepting Devices in accelerator environments;
• Design and integrate control algorithms for electric motors, actuators, and sensor feedback loops to achieve precise motion and positioning;
• Evaluate and characterise sensors and instrumentation, contributing to system calibration and performance optimisation;
• Program and commission industrial PLCs for reliable and safe control of critical hardware systems;
• Collaborate with multidisciplinary teams to interface hardware, control, and data acquisition systems, ensuring seamless integration and operational reliability.

Your profile

• Demonstrates practical experience in motion control, sensing, or automation systems, ideally within an experimental or industrial setting;
• Strong analytical and hands-on skills, capable of both system design and laboratory work;
• Interest in interdisciplinary work, bridging mechanical, electrical, and software domains;
• Excellent teamwork, communication, and problem-solving abilities in a technical environment;
• Your studies focused on Mechatronics Engineering.

Your skills

• Strong knowledge of electric motors, actuators, and their control principles;
• Hands-on experience with laboratory equipment (e.g. signal generators, oscilloscopes, measurement tools);
• Experience in programming industrial PLCs for automation and safety-critical applications;
• Knowledge of programming languages such as C/C++, Python, or similar;
• Strong debugging and problem-solving skills, with attention to reliability and maintainability;
• Ability to work collaboratively in multidisciplinary teams and contribute to shared codebases;
• Spoken and written English, with a commitment to learn French.
