Mechanical Technician for Collimator Systems

Job Posting Organization:
CERN, the European Organization for Nuclear Research, was established in 1954 and is one of the world's largest and most respected centres for scientific research. With over 2,500 employees and thousands of scientists from around the globe, CERN operates in multiple countries and is dedicated to understanding the fundamental structure of the universe. The organization is known for its commitment to diversity and inclusion, which is integral to its mission and success.

Job Overview:
As a Mechanical Technician for Collimator Systems, you will be part of the Targets, Collimators and Dumps (TCD) Section within the Sources, Targets, and Interactions (STI) Group of the Accelerator Systems (SY) Department. This position is crucial for the High-Luminosity LHC Project, specifically within Work Package 5 (WP5). Your role will involve overseeing the production of collimators and masks, which are essential components for the Long Shutdown 3 (LS3) phase of the project. You will be expected to support various operational tasks, including mechanical assemblies, logistics of components, and management of the on-site assembly area. The position requires a proactive approach to problem-solving and a blend of technical skills and hands-on experience to ensure that all assembly and testing procedures are executed efficiently and in accordance with project timelines and quality standards.

Duties and Responsibilities:
Your responsibilities will include executing collimator reception tests and conducting quality checks related to mechanical assembly activities. You will manage tests associated with the collimator's surface mock-up, which involves handling collimators, monitoring tests in collaboration with other CERN teams, and writing detailed test reports. Additionally, you will assist in the removal of collimators from the LHC Machine, organize their storage, and modify radioactive supports as necessary. You will also manage the thermal test bench for collimator jaws located in Italy, which includes replacing parts and conducting maintenance. Organizing transport and packing for hardware, ordering components for surface activities, and managing the production of parts and sub-assemblies for collimators will also be part of your duties. If the project schedule permits, you may participate in the installation of collimators and masks in the machine. The specific responsibilities may vary based on project priorities and scheduling.

Required Qualifications:
To qualify for this position, you must be a national of a CERN Member or Associate Member State. By the application deadline, you should have a maximum of two years of professional experience since graduation in Mechanics or a related field, with your highest educational qualification being a general secondary education diploma. It is important to note that applicants with a Bachelor's, Master's, or PhD degree are not eligible for this position. Additionally, you must not have previously held a CERN fellow or graduate contract.

Educational Background:
The educational background required for this position includes a general secondary education diploma. Candidates with higher educational qualifications such as a Bachelor's, Master's, or PhD degree are not eligible to apply, emphasizing the focus on early-career professionals with relevant secondary education.

Experience:
The position requires candidates to have a maximum of two years of professional experience in a relevant field since graduation. This experience should ideally be in mechanical engineering or a closely related discipline, providing a foundational understanding of the technical aspects of the role.

Languages:
Proficiency in spoken and written English or French is mandatory, with a commitment to learn the other language being essential. This bilingual requirement ensures effective communication within the diverse CERN environment.

Additional Notes:
The job closing date is set for 30.06.2025 at 23:59 (midnight) CEST. The contract duration is 24 months, with the possibility of extension up to a maximum of 36 months. The position requires a commitment of 40 hours per week and involves work in radiation areas and interventions in underground installations. A valid driving license is necessary, as the role includes the use of mobile work equipment or equipment for lifting loads, which requires specific driving authorization. Due to the occupational health risks associated with this position, the selected candidate must obtain medical clearance before a contract offer is confirmed. The job reference is SY-STI-TCD-2025-80-GRAE, and the field of work is Mechanical Engineering. The compensation includes a monthly stipend of 4624 Swiss Francs (net of tax), coverage by CERN's comprehensive health scheme for the employee and their family, and various allowances depending on individual circumstances. Additionally, employees are entitled to 30 days of paid leave per year and will receive on-the-job and formal training at CERN, along with in-house language courses for English and/or French.
