Mechanical Technical Engineer - Vacuum Equipment

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 engineer" style="border-bottom: 1px dotted #007bff !important;">Technical Engineer position within CERN's Vacuum, Surfaces and Coatings (VSC) Group offers a unique opportunity to engage in the upgrade of the world's most powerful particle accelerator, the Large Hadron Collider (LHC). This role is designed for individuals who are eager to apply their mechanical engineering skills in a high-stakes scientific environment. The successful candidate will work closely with a team of experienced engineers, technicians, and physicists, contributing to the installation, testing, and commissioning of critical beam vacuum systems. This position is particularly appealing as it does not require prior experience in particle accelerators; CERN provides comprehensive training and support to help new employees develop specialized skills in vacuum technology and engineering. The role is fully onsite, emphasizing hands-on experience and collaboration in a dynamic international setting.

Duties and Responsibilities:
The duties and responsibilities of the Mechanical Technical Engineer include performing vacuum acceptance testing of components intended for installation in the HL-LHC collimator upgrade. The engineer will test and validate vacuum equipment prior to installation, conduct residual gas analysis (RGA) to ensure compliance with performance and quality standards, and carry out leak tests, bake-out system installations, and non-evaporable-getter (NEG) activation on vacuum components. Additionally, the engineer will assemble and prepare mechanical and vacuum systems for installation and operation, support the installation, testing, and commissioning of equipment for the LHC upgrade program, and prepare technical documentation, test reports, and intervention records. Coordination with suppliers for the procurement and delivery of technical components is also a key responsibility, along with participation in maintenance, upgrade, and repair activities on equipment installed in the LHC tunnel.

Required Qualifications:
Candidates must possess a Bachelor's or Master's degree in Technical and Applied Studies or a related field. They should have a maximum of two years of professional experience since graduation and must be a national of a CERN Member or Associate Member State. Applicants without a university degree or those with a PhD are not eligible for this position. A commitment to learning and adapting to the requirements of the role is essential, as is the ability to work collaboratively in a diverse team environment.

Educational Background:
The educational background required for this position includes a Bachelor's or Master's degree in Technical and Applied Studies or a closely related field. This academic foundation is crucial for understanding the principles of mechanical engineering and vacuum technology, which are central to the role.

Experience:
The position requires candidates to have a maximum of two years of professional experience since graduation. While prior experience in particle accelerators is not necessary, familiarity with helium leak detection methods, on-site vacuum system work, and mechanical installation is advantageous. Basic experience with outgassing phenomena in vacuum systems and knowledge of quadruple mass spectrometers (RGA) for residual gas analysis in ultra-high vacuum (UHV) environments is also beneficial.

Languages:
Proficiency in spoken and written English or French is mandatory, with a commitment to learning the basics of the other language. This bilingual requirement is essential for effective communication within the diverse international team at CERN.

Additional Notes:
The contract duration for this position 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, requiring work in radiation areas and interventions in underground installations. A valid driving license is also necessary. The job reference for this position is TE-VSC-BVO-2026-211-GRAE. Compensation includes a monthly net stipend ranging from 5266 to 5793 Swiss Francs, depending on the candidate's degree, along with 30 days of paid leave per year and additional benefits such as comprehensive health insurance, family allowances, and a relocation package.
