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 CROME for CERN Radiation Monitoring Electronics with very challenging performances and reliability requirements.
The new generation of the radiation monitoring system is running an embedded Linux operating system, executed by an ARM-based System on Chip (SoC). The architecture of the SoC is built on the Zynq 7000 platform, which provides a powerful combination of FPGA flexibility and ARM processing capability. Additionally, preparations are underway for migration to the Zynq UltraScale+, which will further enhance performance, scalability, and reliability to meet the evolving demands of radiation monitoring applications.
We are looking for a talented and detail-oriented designer of Linux-based systems for embedded platforms with a focus on ARM architectures, particularly UltraScale+ Zynq devices to join our team.
Your responsibilities will be to:
* Develop, configure, and maintain Linux-based systems and applications tailored for embedded platforms.
* Work on SoC platforms, with a focus on UltraScale+ Zynq devices, to ensure seamless integration and functionality.
* Design, implement, and troubleshoot heterogeneous computing systems based on ARM/FPGA architecture.
* Collaborate with hardware engineers to integrate custom hardware components with software systems.
* Optimize Linux kernel and driver performance for embedded systems.
* Contribute to system security, reliability, and performance enhancements.
* Prepare and maintain comprehensive technical documentation, including system specifications, configuration guides, and troubleshooting manuals.
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 on hardware/software integration, system performance optimisation, and support innovative product development in a dynamic and collaborative environment.
Required Skills:
* Expertise in Linux operating systems, kernel configuration, and driver development.
* Hands-on experience with System-on-Chip platforms, particularly UltraScale+ Zynq.
* Familiarity with heterogeneous computing architectures and development.
* Proficiency in C/C++, Python, and shell scripting.
* Solid understanding of embedded systems, real-time operating systems, and low-level debugging tools.
* Fluent in English, the ability to work in French would be an advantage
Beneficial Skills:
* Familiarity with FPGA development and integration workflows.
* Experience in HW/SW co-design and optimization for embedded platforms.
* Experience working in an Agile development environment.
