Job Description
Join our team and contribute to the renovation and development of real-time software for the LHC, SPS and AWAKE Beam Position Monitors (BPMs). Your work will focus on re-engineering existing codebases and communication protocols, as well as developing new solutions to integrate SoC-based platforms for the High Luminosity LHC and AWAKE into the accelerator control system.
Your responsibilities
* Re-engineer and refactor low-level C++ code across four existing systems, with the aim of homogenising codebases and improving long-term maintainability.
* Contribute to the development of new AWAKE BPM processing routines.
* Conceive, design and develop software for testing and validation, including hardware-in-the-loop test benches.
* Qualify the integration of the revised legacy and new SoC-based BPM systems into the LHC feedbacks.
* Develop new Python tools and GUIs (graphical user interfaces) for experts.
* Port existing C++ command line tools to Debian.
* Support the teams during commissioning of the developed software once deployed in the accelerator control system.
