Mechanical Manufacturing Engineer

Job Posting Organization:
CERN, the European Organization for Nuclear Research, is a leading research institution established in 195

• It is located in Geneva, Switzerland, and is known for its groundbreaking work in particle physics. CERN employs over 2,500 staff members and collaborates with thousands of scientists from around the world, representing more than 100 nationalities. The organization operates in multiple countries, with its primary focus on advancing scientific knowledge and technology through innovative research and collaboration.

Job Overview:
The Mechanical Manufacturing Engineer position is situated within the Mechanical and Materials Engineering (MME) Group at CERN, which has over 40 years of expertise in mechanical design, manufacturing, and assembly of accelerator and detector devices. The role involves the fabrication of complex components using advanced technologies such as machining, forming, and welding. The engineer will work closely with a multidisciplinary team on various research and development projects, particularly in preparation for the next Long Shutdown (LS3) where significant upgrades to the accelerator complex will occur. This position offers a unique opportunity to engage with industrial partners and gain exposure to diverse manufacturing environments, enhancing the engineer's professional experience and technical skills.

Duties and Responsibilities:
The Mechanical Manufacturing Engineer will be responsible for several key tasks: collaborating with project stakeholders, including project engineers, designers, and draftsmen, to contribute to the design-for-manufacturing phase; reviewing and revising 2D drawings with a focus on geometrical dimensioning and tolerancing; defining make-or-buy strategies to determine the production of components; preparing technical specifications and documentation for tenders and price inquiries; coordinating fabrication schedules and following up on internal manufacturing activities; leading preparatory activities for fabrication, including defining and procuring raw materials and preparing fabrication sequences with quality assurance and control aspects; and managing subcontracted production carried out by external companies. This comprehensive set of responsibilities ensures that the engineer plays a crucial role in the successful fabrication of components essential for CERN's projects.

Required Qualifications:
Candidates must possess proficiency in reading and interpreting 2D drawings and 3D CAD models, particularly with ISO geometrical dimensioning and tolerancing. A solid understanding of manufacturing methods and work preparation is essential, along with familiarity in precision assembly of mechanical structures and equipment. Experience with materials such as Stainless Steels, Aluminum, and Copper Alloys is required, as well as the ability to write technical specifications and fabrication reports. Knowledge of CNC machining techniques, CAD/CAM tools, and joining techniques like welding, brazing, and soldering is considered an asset. Additionally, candidates should have a commitment to learning French, as spoken and written English is mandatory.

Educational Background:
The position requires candidates to be nationals of a CERN Member or Associate Member State and to have a professional background in Mechanical Engineering or a related field. Candidates should hold either a Master's degree with 2 to 6 years of post-graduation professional experience or a PhD with no more than 3 years of post-graduation professional experience. It is important that candidates have not previously held a CERN fellow or graduate contract.

Experience:
The ideal candidate should have a professional background in Mechanical Engineering or a related field, with a minimum of 2 years and a maximum of 6 years of post-graduation experience for those with a Master's degree. For candidates with a PhD, no more than 3 years of post-graduation experience is required. This experience should be relevant to the responsibilities outlined in the job description, particularly in manufacturing engineering and project collaboration.

Languages:
Fluency in spoken and written English is mandatory for this position. Additionally, candidates should demonstrate a commitment to learning French, which is considered beneficial for effective communication within the organization and with local partners.

Additional Notes:
The job closing date is set for 14.09.2026 at 23:59 CEST. The contract duration is 24 months, with the possibility of extension up to a maximum of 36 months. The working hours are set at 40 hours per week, and the position is fully onsite. The target start date for this role is 01-July-202

• A valid driving license is required for this position. The job reference is EN-MME-FS-2026-81-GRAP, and it falls under the field of Mechanical Engineering with a benchmark job classification of 200090 - Mechanical Engineer. The compensation includes a monthly net stipend ranging from 6372 to 7004 Swiss Francs, depending on the candidate's degree, along with 30 days of paid leave per year, comprehensive health insurance coverage, family allowances, a relocation package, and opportunities for on-the-job training and formal language classes.
