We invite you to take your career to an exciting new level by joining the team of operators who run the CERN accelerator complex from the CERN Control Centre (CCC). Functions
Take part in the 24/7 shift team which runs CERN's accelerator complex. Operate proton and/or ion accelerators (Linac3, Linac4, PSB, LEIR and/or PS) and the beam lines to the associated experimental facilities on a shift basis, ensuring the safe and timely execution of the physics schedule and obtaining the defined beam performance goals. Work closely with accelerator physicists to set up and optimise the accelerator operation and to design, document, commission and optimise various operational scenarios. Participate in the development of applications and advanced tools as part of a team or in collaboration with engineers or physicists within the OP group or within a specialised equipment group. Outside periods of accelerator operation, assist the technical infrastructure team with the operation of CERN's technical infrastructure or other CERN equipment groups, if required. Experience and Qualifications
Higher Technical or Administrative Diploma or equivalent in the field of Administration, Computer Engineering, Data Analysis (non-exhaustive) or a related field. Initial work experience in a technical or scientific environment. Experience in the field of physics, engineering or computing. Basic knowledge of software engineering in a modern development language environment. Familiarity with automation concepts and techniques, with an interest in improving operational efficiency and reliability. Drive to work collaboratively in a multidisciplinary team and contribute to continuous operational improvements. Experience in operating large facilities and their associated hardware (e.g. measurement devices, power converter techniques, vacuum equipment, PLCs, work in controlled radiation areas, etc.) would be an asset. Technical Competencies
Operation of accelerators. Analysis and optimisation of accelerator performance. Testing and validation of detector, accelerator and beam line components. Knowledge of programming techniques and languages. Development of application software. Behavioural Competencies
Working in Teams: cooperating constructively with others in the pursuit of team goals; balancing personal goals with team goals. Managing Self: taking initiative beyond regular tasks and making things happen. Solving Problems: anticipating obstacles; assessing alternative solutions in order to have a fall-back plan. Communicating Effectively: ensuring that information, procedures and decisions are appropriately documented. Demonstrating Accountability: taking responsibility for own actions and decisions. Language Skills
Spoken and written English or French, with a commitment to learn the other language. Eligibility and Closing Date
Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success. We welcome applications from all Member States and Associate Member States. This vacancy will be filled as soon as possible, and applications should normally reach us no later than 29.07.2026 at 23:59 CEST. Employment Conditions
Contract type: Limited duration contract (5 years). Subject to certain conditions, holders of limited-duration contracts may apply for an indefinite position. Working Hours: 40 hours per week Job Flexibility
Shift work, including nights, Sundays and official holidays. A valid driving licence. Given the occupational health risks associated with this position, the selected candidate must obtain medical clearance before a contract offer is confirmed. Job Grade and Reference
Job grade: 3-4 Job reference: BE-OP-PSB-2026-141-LD Field of work: Electrical or Electronics Engineering Benchmark Job Title: Accelerator/Industrial Process Operations Technician Benefits
A competitive salary (tax free), increasing in line with your years of relevant experience. 30 days of paid leave per year plus 2 weeks annual closure. Coverage by CERN’s comprehensive health insurance scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund. Family, child and infant monthly allowances depending on your individual circumstances. A relocation package (installation grant, removal, travel expenses) depending on your individual circumstances. Possibility to extend your contract up to 8 years + eligibility for indefinite contract tenure.
