At CERN, the European Organisation for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature.

Job description
Join the Automatic Control & Safety (ACS) section of the CERN Industrial Controls group (BE-ICS) and contribute to the control systems for the Primary Gas Systems (PGS) that supply detectors and installations across CERN's Experimental Areas.
A central activity is the migration of the LHC Primary Gas Systems to a dedicated Experimental Areas infrastructure, regrouping their development, maintenance and first-line support.
You will work across the full control stack - from PLC logic and field instrumentation to WinCC OA supervision - using CERN's model-driven Gas Control System (GCS) and UNICOS-CPC frameworks.
Your responsibilities
Contribute to the migration of the LHC Primary Gas Systems, covering PLC and SCADA (WinCC OA) development and commissioning.
Develop and configure gas-system control applications on Schneider M580 and Siemens S7-1500 PLCs.
Contribute to the specification, I/O definition and instrumentation of primary and detector gas systems and to HMI, touch-panel and notification (email/SMS) development.
Support factory and site acceptance testing (FAT/SAT), installation and commissioning in the experimental areas, together with documentation and first-line operational support.
Your profile
Interest in industrial control systems and hands-on work with hardware, instrumentation and field installations.
Strong problem-solving skills and the ability to work within a multidisciplinary team.
Good communication skills in English, with the ability to document and present technical work clearly.
Skills
Some knowledge of PLC programming (IEC 61131-3) on Schneider and/or Siemens platforms, or willingness to learn.
Familiarity with SCADA systems (WinCC OA an asset) and industrial communication protocols such as PROFIBUS, PROFINET, Modbus or Flowbus.
Proficiency in a scripting or programming language such as Python.
Interest in field instrumentation and gas/fluid systems.
Knowledge of continuous integration (GitLab CI) or model-driven code generation an asset.
Spoken and written English, with a commitment to learn French.
Eligibility criteria:
You are a national of a CERN Member or Associate Member State.
By the application deadline, you have a maximum of two years of professional experience since graduation in Automation, Control Engineering (or a related field) and your highest educational qualification is either a Bachelor's or Master's degree.
You have never had a CERN fellow or graduate contract before.
Applicants without University degree are not eligible.
Applicants with a PhD are not eligible.
This position involves:
Work in Radiation Areas.
Interventions in underground installations.
A valid driving licence.
What we offer
A monthly net stipend of either 5,266 or 5,793 Swiss Francs per month depending on your degree.
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 and travel expenses) depending on your individual circumstances.
Possibility to extend your contract up to 36 months.
On-the-job and formal training including language classes.
We've signed the Gradcracker feedback pledge.
(This means that we will supply feedback if requested after an interview.)
