• Conduct technological watch and evaluate emerging technologies to ensure high-quality solutions aligned with CERN’s evolving accelerator controls environment.
• Collaborate with stakeholders, including end users, Product Owners, and infrastructure providers, to gather requirements and define solutions.
• Support accelerator equipment experts, physicists, and operation crews by improving and optimising their experience with the platform and associated software services.

Requirements

• Master's Degree or equivalent relevant experience in the field of Computer Science or a related field.
• Proven solid experience in software development using Java.
• Hands-on experience with Python.
• Strong knowledge of the Spring Framework ecosystem.
• Practical experience with concurrent and multi-threaded programming.
• Good understanding of distributed systems and JVM internals.
