Online Software Developer (EP-CMS-TDQ-2026-153-GRAP)

The role of Online Software Developer (EP-CMS-TDQ-2026-153-GRAP) involves contributing to the upgrade of the CMS data acquisition system for the High-Luminosity LHC. The company, CERN, is a renowned research organization focused on particle physics and accelerator technologies. The main day-to-day responsibilities include developing software to configure, control, and monitor the Trigger and Timing Control and Distribution System (TCDS). This involves close interaction with hardware components and collaboration with electronics engineers, physicists, and other stakeholders. Additionally, the role requires setting up and operating DAQ test systems, maintaining software repositories and CI/CD infrastructure, and contributing to the installation and commissioning of the Phase-2 DAQ system. Support for the CMS community in commissioning sub-detector data acquisition components is also part of the job. To qualify for this role, candidates must have proficiency in designing and developing complex applications in Python and C++, including user-facing and REST-based interfaces. Experience with system programming and interaction with computer hardware is essential. Additionally, experience in collaborative software development and CI/CD practices is required. Candidates must be nationals of a CERN Member or Associate Member State and have a professional background in Software Engineering or Applied Physics, or a related field, with a Master's degree or equivalent experience. Nice-to-have skills include familiarity with firmware development using hardware description languages such as VHDL or Verilog, and some exposure to the challenges of data acquisition systems in modern high energy physics (HEP) experiments. The role is based at CERN, which offers a dynamic and collaborative work environment. The team is multidisciplinary, and the conditions are conducive to professional growth and development. What the role asks for: - Nationality of a CERN Member or Associate Member State. - Master's degree in Software Engineering or Applied Physics, or a related field. - Proficiency in Python and modern C++.
