Your responsibilities

CERN designs, develops, and operates particle accelerators and experiments for scientific research to understand the fundamental laws of the universe. These activities may generate stray radiation due to the interaction between beams and matter. The radiation detectors installed close to the various beam lines and targets allow CERN to accurately monitor radiation levels. Within the Radiation Protection (RP) Group at CERN, the Instrumentation & Logistics (IL) Section is responsible for the design and the development of this specialised equipment, as well as its installation, commissioning, operation and maintenance.

Radiation monitoring is essential to enable CERN to operate its accelerator complex and related experiments while fulfilling its legal obligations to protect the public, people working on CERN site and the environment. In this stringent context, the RP-IL Section has developed a new generation of radiation monitoring system called CROME (https://crome.web.cern.ch) for CERN Radiation Monitoring Electronics with very challenging performances and reliability requirements.

Within the framework of this development activity, the RP-IL Section has designed two complementary electronics:

1. A new generation of ASIC front-end with specific requirements linked to radiation protection detectors. This circuit is a ten-decade silicon CMOS current to frequency converter capable of measuring a current over a wide range from 2fA to 20 µA;
2. A modular and reconfigurable electronics based on a heterogeneous multiprocessor system-on-chip (MPSoC) for both real-time control and complex computation.

We are looking for a talented and detail-oriented FPGA Engineer with microelectronics knowledge to join our team. This role is focused on FPGA development, with a special emphasis on characterizing ASICs and working with System-on-Chip (SoC) platforms, particularly the Zynq UltraScale+ family.

You will work in a team of engineers and technicians to:

• Develop and optimize FPGA designs for ASIC characterization and system validation.
• Work with SoC platforms, especially Zynq UltraScale+, to implement high-performance, low-latency and resilient system.
• Design and implement hardware/software interfaces for SoC platforms.
• Analyse and debug FPGA designs using simulation and test tools.
• Develop scripts and tools for automating FPGA workflows and data analysis.
• Create comprehensive technical documentation, including design specifications and test plans.

You will work in an innovative and dynamic environment, collaborating closely with electronics engineers and technicians. This role offers a unique opportunity to contribute to cutting-edge radiation monitoring technologies while engaging in interdisciplinary teamwork to develop high-performance and reliable embedded systems.

Your profile

The ideal candidate will have good skills in microelectronics, embedded systems, and hardware/software co-design.

Required Skills:

• Expertise in FPGA design and development (VHDL, Verilog, or SystemVerilog).
• Hands-on experience with SoC platforms, particularly Zynq UltraScale+.
• Knowledge of microelectronics, ASIC characterization, and verification techniques.
• Proficiency in simulation and debugging tools like ModelSim, Vivado, and ChipScope.
• Experience with hardware/software co-design and embedded development.
• Proficiency in scripting languages (Python, Tcl, or similar) for automation tasks.
• Fluent in English, the ability to work in French would be an advantage.

Beneficial Skills:

• Knowledge of FPGA-accelerated computing and heterogeneous system architectures.
• Familiarity with ASIC testing

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• You have a professional background in Electronics / Microelectronics (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.
