You will join a team that is responsible for the development and evolution of CERN's industrial control frameworks, JCOP and UNICOS, as well as for evaluating and validating new technologies for future control systems.
These frameworks build on the commercial SCADA platform SIMATIC Win CC Open Architecture (Win CC OA) from Siemens, which forms the backbone of more than 800 mission‑critical control systems.
Starting in a few months, the LHC detectors will undergo major upgrades requiring new control systems and additional functionality in the JCOP Framework. In this context, you will contribute to the development and evolution of the JCOP Framework and support the implementation of detector control systems.
Your responsibilities Contribute to the development and evolution of the JCOP Framework used by the LHC experiments.
Implement and maintain software components, templates and tools based on Win CC OA and CERN control frameworks.
Design & Development of user interfaces with Win CC OA.
Prototype and test new solutions to improve reliability, maintainability and scalability of the frameworks.
Integrate devices into supervisory control systems.
Assist LHC experiments in the development, deployment and maintenance of their control systems.
Participate in code reviews, debugging and troubleshooting of control system applications. Your profile Initial experience or exposure to software development in distributed or modular systems.
Experience with modern programming languages and development tools (e.g. C/C++ or similar).
Knowledge of software engineering principles (version control GIT, testing, code quality, documentation, CI/CD).
Knowledge of Qt, Node.js or Type Script would be an advantage.
Familiarity with industrial control systems, SCADA technologies, or CERN experiment online systems would be an advantage. Skills Proficiency in C/C++ programming.
Ability to learn and adapt to new technologies and frameworks quickly.
Ability to design, implement and debug software components in complex systems.
Strong analytical and problem‑solving skills.
Ability to work in multidisciplinary teams and interact with engineers and scientists.
Good communication and documentation skills.
Spoken and written English, with a commitment to learn French. Eligibility criteria You are a national of a CERN Member or Associate Member State.
