Job Description

Your responsibilities

Are you a passionate hardware developer who loves to tackle challenging problems that help advance basic science? Do you enjoy working with modern technologies? Then come join us to develop a next generation electronics board for data acquisition at the Compact Muon Solenoid (CMS) experiment, one of the major detectors at the LHC.

At CMS, we face the task of processing collisions between proton bunches at up to 40 MHz, which would generate an immense data rate. Our level-1 (L1) trigger, employing custom firmware logic in hundreds of FPGAs, selects promising events in microseconds for data acquisition and further detailed analysis. We’re currently upgrading the trigger and data acquisition systems for the future high-luminosity phase of the LHC.

One of our R&D activities is exploring the potential of a complementary system called L1 Data Scouting, which would analyze a data stream containing all events but with just the coarse grain L1 trigger information. To fully exploit the potential of such a system, we would like to develop a novel data acquisition board based on the latest generation FPGAs and high-speed network technology – and you will be the architect of this board.

This R&D is in the broader context of the NextGen Triggers project, a 5-year collaboration between the LHC experiments and the CERN Research and Computing Departments to push forward the use and impact of innovative Artificial Intelligence technologies and high-performance computing architectures for the LHC experiments’ trigger selection, data processing, and theoretical interpretation.

Responsibilities:

• Develop the concept, schematics and PCB layout for the new data acquisition board, and follow the manufacturing and hardware testing of the first prototypes.
• Support and contribute to the development of firmware for the board, and its integration in the L1 Data Scouting demonstrator system
• Providing day-to-day supervision of students working on the project.
• Collaborating with personnel and students from the CERN CMS L1 trigger and data scouting groups.
• Presenting work at conferences and workshops at CERN and beyond.

Your profile

Skills

• Experience with all the steps to develop a high-speed electronics board: schematics, PCB layout, submission for production and assembly, testing, development of FPGA firmware.
• Experience with AMD Xilinx FPGAs and Systems-on-chip (Versal, Zynq) and the associated software (Vivado, Vitis) would be highly beneficial.
• Experience with the CMS L1 trigger / data acquisition systems and the associated hardware would be beneficial.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• A limited number of positions are also available to candidates from Non-Member States.
• You have a professional background in Physics or Electronics Engineering (or a related field) and have either:
  • a Master’s degree with 2 to 6 years of post-graduation professional experience;
  • or a PhD with no more than 3 years of post-graduation professional experience.
• You have never had a CERN fellow or graduate contract before.

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.
