Your responsibilities
Starting from Run 3 of the LHC, the upgraded LHCb experiment is taking data with a triggerless readout system. A fully software-based high-level trigger (HLT), split in two stages, selects the events with unprecedented flexibility. The first stage, implemented on GPGPUs, runs inclusive selections based on a subset of the reconstruction. The second stage runs the full offline-quality reconstruction and physics selections on a CPU farm, directly providing events ready for analysis. Thanks to the flexibility of the system, improvements are happening continuously, which is why it is crucial to maintain a strong operations team throughout the run. In parallel, the collaboration is ramping up an effort to design the software that will be needed for Run 4 of the LHC and beyond.
In this role you will become part of LHCb’s Real Time Analysis project, comprised of physicists and engineers running and managing the current HLT and envisaging the trigger for a future upgrade of LHCb. You will collaborate with an international team of experts from the areas of computing, detector design and construction, online and offline data processing and alignment and calibration.
After an initial period of learning the HLT software architecture and its operational requirements, you will take part in some of the following activities:

What we offer
About us
At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world’s largest and most complex scientific instruments, they study the basic constituents of matter – fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern.
