Join the software team in the Machine Protection and Electrical Integrity (MPE) group and help shape the future of the High Luminosity LHC. In this role, you'll contribute to the evolution of the Quench Protection System (QPS) software and its integration within CERN's accelerator controls.
Working with modern technologies (Rust, C++, Python, Java), you'll support a live system already deployed in cutting-edge test facilities. You'll collaborate with experienced engineers, gain hands-on experience, and help improve the reliability, usability, and integration of critical software systems. We welcome curious, motivated graduates who are eager to learn, contribute, and grow in a collaborative and inclusive environment.
Your responsibilities:
-
Contribute to the maintenance and evolution of the Rust-based data acquisition system and its client libraries (Python and C++).
-
Support the development and testing of real-time control software.
-
Assist in integrating the software stack within CERN's wider controls ecosystem, including access control systems (RBAC).
-
Help document and improve the QPS functional model and its interactions with other systems.
-
Participate in the maintenance of the existing QPS data acquisition system currently used in the LHC.
-
Collaborate with stakeholders and users to understand requirements and support ongoing operations.
