Software Developer - Beam Optics (BE-ABP-LNO-2026-132-GRAP)

Maintain and extend the core OMC framework and toolset used during LHC commissioning and operation. Explore software solutions to improve the efficiency and capability of optics measurement and corrections in the LHC. Update accelerator model creation and correction algorithms to utilise new simulation tools. Explore the viability of automation for key measurement and analysis workflows, implementing solutions where possible. Develop new GUIs and analysis tools to be used in the CERN Control Centre during optics commissioning. Participate in, and contribute to the analysis of, optics measurements in the CERN accelerators.

At CERN, the European Organization for Nuclear Research, we are pushing the frontiers of science and technology. Our groundbreaking work brings together not only physicists but also a diverse range of professionals from engineering, technical, scientific, and administrative fields. Together, we foster an environment where innovation and collaboration thrive. Every day, we face exciting new challenges and opportunities to contribute to cutting-edge research that shapes our understanding of the universe. We meet these challenges through the diverse perspectives within our teams, ensuring every contribution is valued and driving our shared sense of inclusion and purpose. Diversity is a core value of CERN since its foundation, and it remains central to our mission and continued success.
