Embedded Software Engineer (BE-CEM-MRO-2026-156-GRAP)

Help shape the future of the Large Hadron Collider (LHC) machine protection systems. We are looking for a motivated Engineer to contribute to the renovation of the LHC Collimator Control System, a critical component ensuring the safe and reliable operation of the world's most powerful particle accelerator. Working in a highly collaborative environment you will help to increase the reliability, usability, and long-term maintainability of systems at the heart of LHC operations. This is a unique opportunity to combine software development, controls engineering, and accelerator technology while making a tangible impact on CERN's flagship facility.

- Develop and maintain control applications for the LHC Collimator system using the FESA framework, ensuring integration within CERN's accelerator control environment. - Coordinate and support control system commissioning, performing functional testing, validation, and verification of interlocks and fail-safes prior to operational deployment. - Integrate control systems with the alarm server and develop high-level tools to enhance usability and real-time monitoring. - Contribute to the design and validation of system-level tests, including functional, integration, and regression testing. - Support expert and operational interfaces, providing diagnostic capabilities and improving intervention workflows.

- Demonstrated experience in real-time or distributed control systems, preferably within accelerator, industrial automation, or scientific environments. - Experience in interventions in complex industrial or technical environments. - Experience developing and maintaining expert interfaces (GUIs, web tools) for control and diagnostics. - Experience with software version control (e.g. Git) and CI/CD workflows.

- Proficiency in C++. - Knowledge of Python. - Skilled in system integration, commissioning, and validation of control applications for hardware-software systems. - Strong ability to troubleshoot, analyse, and document complex technical issues in operational environments. - Proactive, organised, and collaborative, with the ability to work effectively in multidisciplinary engineering teams and communicate technical progress clearly. - Spoken and written English, with a commitment to learn French. Eligibility criteria: - You are a national of a CERN Member or Associate Member State . - You have a professional background in Controls Engineering, Computer Science, Electronic Engineering (or a related field) and have 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. - You have never had a CERN fellow or graduate contract before.
